Kizilcahamam-Camlidere Geopark (Ankara/Turkey) with its Geological Heritage Values and Geotourism Planning
Authors: Kocan Nurhan , Yucesoy Nese 
Published: January 2016

Abstract:
Geological heritage areas have lot of information about the formation of the earth, its history as well as ecological and aesthetic and resource values to attract different tourism activities. Unique geological and geomorphologic structures attract the attention of scientists and nature lovers. Turkey’s first geopark Kizilcahamam-Camlidere Geopark needs evaluation with its twenty-three geosites and different tourism activities. While a part of this potential is being used the remaining portion has to be developed. This study aims to assess Kizilcahamam-Camlidere Geopark and its surrounding within the frame work of planning so that it can become operating and to guide the project practitioners in this aspect. In this study visual analysis, SWOT analysis, surveys, work of focus group etc are used. Autocad 2012, Photoshop CS5 softwares are used for preparing drawings of the plan. From the study geotourism planning has been proposed.
Thermal-oxidation mechanism of dioctyl adipate base oil
Authors: Qian Xuzheng , Xiang Yaling , Shang Hongfei , Cheng Bingxue , Zhan Shengpeng , Li Jian 
Published: January 2016

Abstract
The ester base oil of dioctyl adipate (DOA) was oxidized in an oven at 200 °C for 30 h, and variations in the physicochemical and tribological properties were studied. To investigate the thermal-oxidation mechanism, the thermal-oxidation products were analyzed by gas chromatography–mass spectrometry (GC−MS), and the thermal-oxidation process was simulated using visual reactive force field molecular dynamics (ReaxFF MD). The results indicated that the total acid number (TAN) increased significantly because of the presence of 14% carboxylic acids and low molecular weight monoesters. The tribological properties were improved by the formation of the strongly polar carboxylic acids. Additionally, the increase in kinematic viscosity was limited due to the formation of high molecular weight polymerization products and low molecular weight degradation products. Thermal-oxidative degradation and polymerization mechanisms were proposed by combining ReaxFF MD simulations and GC−MS results.
Insights into the Earliest Formative Period of Coastal Ecuador: New Evidence and Radiocarbon Dates from the Real Alto Site

Published: January 2016

AbstractOne of the most intriguing questions of South American archaeology is the time, place, and origin of the earliest pottery. Since the late 1950s, the earliest pottery has been attributed to the materials of the Early Formative Valdivia culture (5600–3500 BP), coastal Ecuador. Excavations at the Real Alto site conducted in the 1970s and 1980s allowed the rejection of the spectacular “Jomon–Valdivia” hypothesis and established a local origin of the phenomenon. Recent radiocarbon dates from a joint Russian–Japanese–Ecuadorian project at Real Alto open a new page in our knowledge of the transition from pre-ceramic Las Vegas to ceramic Valdivia cultures.
Prehistoric Fishing Methods in South Africa
Authors: Goodwin A. J. H. 
Published: January 2016

In the course of many years of archaeological research in South Africa, cut off by the length of the continent from the European scene, various local problems, unrelated to those of Europe, necessarily arise. One of the most persistent has been that of the origin and age of coastal fishing enclosures whose distribution extends sporadically from the mouth of the Berg river in St. Helena Bay (northwest of Cape Town) to Kosi Bay on the Zululand coast, and perhaps even further in either direction. The known coastal range is well over 1000 miles. Any complete solution of the various problems raised must necessarily be shelved until petrol supplies permit the careful excavation of a series of surrounding midden deposits.The enclosures are known locally as vywers (pronounced much as the English ‘favours’) or sometimes as viskraals, literally dams, or fish-corrals, and we can speak of them in English as tidal fish-traps. Happily their use continues, in a somewhat sporadic way, at several of the sites, and we can still study the methods used. In brief, the enclosure is built up as a dry-stone wall to such a height that normal high tides will cover the vywer and permit fish to swim freely over the enclosed area. As the tide sinks, the water runs out through the interstices between the stones, while the fish are trapped and can be clubbed and caught by hand. It is a simple application of the system used for netting fish, though here the dry-stone walling provides the imbrications.
The Role of Birds in Early Navigation
Authors: Hornell James 
Published: January 2016

It is not generally recognized how important a part was played by birds in the guidance of early voyagers when sailing on the uncharted seas of the ancient world, and how their regular migrations year by year and season by season, along definite routes have contributed to the discovery of many lands and isolated islands. We know that Columbus made his first American landfall by noting the south-westerly direction taken by great flocks of small field-birds seen flying overhead in the evening towards land as yet out of sight of those aboard the ships; we know, too, that the significance of their flight was at once recognized, for did not Pinzon point out its meaning to his crew by his remark ‘Those birds know their business’ (Morison, 1841, 664-5)?How true his words were we now know, for it is about the time of year (October) when Columbus saw these battalions of birds darkening the sky, that certain species of landbirds set out from the eastern shores of North America by a southerly route, via Bermuda, to seek a warmer climate and a more plentiful supply of food.
Language as a Means to an End
Authors: Gordon Cyrus H. 
Published: January 2016

To investigate any topic properly, we should exploit all the evidence bearing upon it. The study, therefore, of any period of antiquity documented both by artifacts and texts, requires the synthesis of archaeology and philology. He who would control any period of history, must master its written as well as its archaeological sources.The growth of knowledge, and the development of new techniques, evoke more and more specialization. This has happened particularly in the study of man as a result of the masses of data that keep pouring in, during an age of discovery through exploration and excavation.
Megalithic and Other Art: Centre and West
Authors: Powell T. G. E. 
Published: January 2016

The occurrence of designs cut on the stone walling slabs of certain prehistoric tombs in Central Germany has led from time to time to a search for comparisons, even prototypes, in the mural art of megalithic tombs in Atlantic Europe. Within recent years, some new observations and discoveries of considerable interest have been made principally as a result of a re-excavation at the well-known Lohne (Züschen) megalithic tomb near Fritzlar, and through the excavation of a tumulus on the Dölauer Heide near HallelSaale (FIG. I).The first of these monuments is a large, megalithically constructed, collective tomb with a long rectangular chamber entered through a port-hole slab which is set between the main chamber and a short ante-chamber. The whole monument is set in a trench so that the roof was approximately at ground level. This is one of a group of such tombs in Hesse; there is a neighbouring group in Westphalia, and these are related both to a group in Sweden, and, more particularly, to the classic tombs of this type in the Paris Basin (SOM). The Dölau tumulus is something quite different, for in it, amongst other things, has been found a stone-constructed grave for only one individual. The wall and cap-stones are of moderate size but not megalithic, and the grave can be likened in various respects to some three other stone-built graves, all in the Halle district, and of which the best known was that found at Göhlitzsch with its representations of bow, quiver, and battle-axe, cut, with other decoration, on the wall faces.
The Accuracy of Radiocarbon Dates
Authors: Libby W. F. 
Published: January 2016

The first test of the accuracy of dates obtained by the radiocarbon technique was made by determining whether dates so obtained agreed with the historical dates for materials of known age (n. 1). The validity of the radiocarbon method continues to be an important question, especially in the light of the numerous results that have been accumulated and the greater precision of the technique during the past few years (n. 2).The radiocarbon content of the biosphere depends on three supposedly independent geophysical quantities: (i) the average cosmic ray intensity over a period of 8000 years (the average life of radiocarbon) as measured in our solar system but outside the earth's magnetic field (n. 1); (ii) the magnitude (but not the orientation, because of the relatively rapid mixing over the earth's surface) of the magnetic field in the vicinity of the earth, averaged over the same period (n. 1,3); and (iii) the degree of mixing of the oceans during the same period (n. 1). The question of the accuracy of radiocarbon dates therefore is of interest to geophysicists in general as well as to the archaeologists, geologists and historians who use the dates.Previous workers in this area (n. 1, 2) have reported some discrepancies, and it is the purpose here to consider the matter further.
Ultra-Violet Radiation and Excavation
Authors: Ritchie P. R. , Pugh J. 
Published: January 2016

The difticulties surrounding the proper excavation and display of poorly preserved skeletal remains are well known to excavators. Where the bone is moist and friable, care is required to avoid touching it until it has dried and hardened. When it is stained as well, so that there is little contrast between bone and soil, then the excavator's task can indeed be difficult. In such cases photographic presentation often shows less than was seen by the excavator since differences just perceptible to the eye are likely to fall well short of the contrast level which can be recorded satisfactorily by the camera. Those sandy soils in which the stain is well displayed are the fortunate exception. In an endeavour to overcome these difficulties ultra-violet radiation has been tried.The light of the visible spectrum extends from a wavelength of 7,000 Å at the red end to 4,000 Å at the blue end (n. 1). The shorter wavelengths extending to 140 Å form the ultra-violet region, but most of this is lost for present purposes since ordinary optical glass absorbs all radiation below about 3,500 Å. However, phenomena which can be used are found in this band between 3,500 Å and 4,000 Å. Emissions of these wavelengths are not visible to the human eye but some substances possess the property of absorbing such radiation and in turn emitting new radiation at longer wavelengths, including those which are visible. This is the phenomenon known as fluorescence.
Lébous
Authors: Arnal J. , Martin-Granel H. , Sangmeister E. 
Published: January 2016

We have been 50 bold as to call the LCbous site a ‘castle’ because, architecturally, it is in plan very like a medieval castle: it is trapeze-shaped, measuring 50 m. on two sides and 75 m. on the other two sides, and it is reinforced at its angles and along its walls with round towers. The enclosure is of dry stone walling about a metre thick, and the towers are about 2 m. 50 cm. in diameter inside, and spaced 24 m. apart from each other. On the north face a tower has been replaced by a rectangular entrance protected by two walls arranged like antennae (FIG. 2). The walls now stand only 60 to 80 cm. high, but one imagines that originally they rose to a height of 1½ m. (PL. XXVIII).It is not suggested that we are dealing with a castle in the strict sense of that word: surely Ltbous is a fortified village site, and as such unique in the prehistory of western Europe and of very great importance. We need not concern ourselves here with the history of the discovery of the site, except to say that in the course of the excavation of seven Hallstatt barrows, tower no. 3 was found underneath them. As the towers and walls are all covered by Hallstatt and Bronze Age barrows, a late Roman wall, medieval. constructions, and even ploughed fields (surprising for garrigue country), it is not surprising that it took nearly seven years to discover the true nature of this fortified village.The site is 1 km. south of the village of St-Mathieu and in the commune of St-Mathieu-de-Tréviers on the ridge known as the Ltbous [1]. Our excavations have already been published in France and Germany [2]; here we wish to summarize our work for English readers and to refer to the most recent excavations, hitherto unpublished.
A View of Etruscan Origins
Authors: Hencken Hugh 
Published: January 2016

In recent years there have appeared a number of books about the Etruscans. These have for the most part been devoted to Etruscan art and culture of the historical period, and touch only lightly on the so-called mystery of Etruscan origins. This mystery is a peculiar thing, for no one regards the origin of other ancient peoples such as the Greeks or the Romans as mysterious. It is simply assumed that they developed where they are found at the beginning of history out of various prehistoric elements that had already arrived.The Etruscan mystery arises in part from the remarkable differences both in language and in civilization between the Etruscans and the other peoples of pre-Roman Italy. The ancients also speculated about it, and the puzzle is in part due to contradictory statements made by them. Herodotus in the 5th century B.C. said that the Etruscans came from Lydia, and Dionysius of Halicarnassus in the 1st century B.C. said that they did not come from anywhere but originated in Italy. The aim of much discussion in recent times has been to determine which was right. I should say at once that it seems to me that there is something in both views. But the statement of Herodotus can hardly be taken literally, since there is insufficient specific connexion between the ancient language and culture of Lydia and anything in Etruria. I shall return to that part of the story later.
Climatic Change in Mycenaean Greece
Authors: Wright H. E. 
Published: January 2016

The essence of historical research is the search for the cause of a major event. The same applies to prehistoric research, except that the documents cited in evidence lack written records and may require greater speculation.One of the major events in the history of Greece was the fall of the Mycenaean civilization, which occurred about 1200-1100 BC and ushered in the Greek Dark Ages, when populations in the former Mycenaean lands were small and political organization dispersed. Although falling, strictly, within the historic period, thanks to the recent decipherment of Mycenaean written documents, the available records merely illustrate some of the business transactions of several flourishing kingdoms they give no clues to the cause for the abrupt demise of the culture.It is on this subject, with its paucity of direct evidence, that Professor Rhys Carpenter introduces some speculations drawn from natural science-the notion that climatic change in southern Greece caused repeated failure of crops and the consequent breakdown of the Mycenaean economy.
The Composition of Metal Artifacts: a Guide to Provenance?
Authors: Tylecote R. F. 
Published: January 2016

This is probably the question most often asked of the metallurgist by the archaeologiist, and the object of this report is to show how far we have got in our attempts to answer it.First, it must be clearly understood that we can only expect some correlation between ore and weapon or utensil, and therefore provenance in the early eras of metallurgy, where the bulk of the metal used emanated from primary sources, and where the amount of secondary re-used metal was negligible. This objection does not apply, however, in the case of semifinished products such as those ingots which have been made from ores and not from secondary material. This should include the plano-convex copper ingots of Late Hronze and Roman date in Britain and the ox-hide ingots of the Eastern Mediterranean.
The Mycenaean sanctuary at Phylakopi
Authors: Renfrew Colin 
Published: January 2016

Professor Renfrew, who holds the Chair of Archaeology in the University of Southampton, has prepared for us an account of the sanctuary at the important site of Phylakopi in the Cycladic island of Melos, excavated by the British School of Archaeology at Athens from 1896 to 1899. The publication (Atkinson et al., 1904) was a landmark in the study of European prehistory. The person in day-to-day charge (although not nominally Director) was Duncan Mackenzie, who later assisted Evans at Knossos. Mackenzie's Daybooks have been preserved and are a useful source of stratigraphic information.Excavation was resumed in 1974–7, directed by Professor Renfrew, for the British School of Archaeology at Athens, with the authority of the Greek Archaeological Service. The most important and altogether unexpected result has been the discovery of a sanctuary of the Mycenaean period, with a number of very beautiful finds (cf. Frontispiece)* as well as some highly unusual ones (male figurines). The only well-preserved Mycenaean shrine previously excavated is that at Mycenae itself, discovered by Lord William Taylour and first published in this journal (Taylour, 1969 and 1970).The Phylakopi shrine is of great importance for the Mycenaean period in the Cyclades, for the understanding of Mycenaean cult and religion, and for the several works of art which it has yielded, including the Lady of Phylakopi, perhaps the most beautiful of the ceramic cult figures known from the Mycenaean world.
Megaliths galore
Authors: Daniel Glyn 
Published: January 2016

The Inventaire des mégalithes de la France—Région Parisienne is the fourth in the French series which began with Cordier's inventory of Indre-et-Loire (1963) and continued with Gruet's inventory of Maine-et-Loire (1967) and Despride and Leymarios's inventory of Loir-et-Cher (1974). All these have been published as supplements to Gallia Préhistoire and we are now promised a fifth volume by Jean Clottes on the megaliths of the Lot. The present volume is by far the biggest and most important in the series so far and it deals with the monuments in the present six departments of Paris, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de- Marne, and Val d'Oise, which used to be the departments of Seine and Seine-et-Oise.The author of this inventory is an English civil servant, now in high international office in Brussels, who formerly was in Paris and there spent his week-ends picnicking in megaliths, and what better employment could there be for our international civil servants? As he says, with characteristic modesty, of his Paris days, ‘Au commencement vers 1955 ou 1956, la prtparation de cet inventaire servait uniquement de distraction pour mes moments perdus et n'avait aucune prétention. Ce ne fut que beaucoup plus tard qu'il m'a été suggéré de le proposer à la présente série. La distraction transformée en devoir, c'est alors que le travail a commencé pour de bon.’
How to cope with calibration
Authors: Pearson Gordon W. 
Published: January 2016

The first calibration curve, published by Suess in 1967 (Suess 1967), was a wiggly thing arrived at by a process Suess called ‘cosmic schwung’. Later curves used more formal statistical methods, including Clark's published in ANTIQUITY (Clark 1975), which came to be one of the most used. It would be good to have the new standard curves available in ANTIQUITY, but they are far too bulky. We recommend the now-indispensable calibration issue of Radiocarbon (Stuiver & Kra 1986), which takes 230 large-format pages to set them out as tables, graphs and a computer program.Gordon Pearson is the British end of the Anglo-American axis, with Minze Stuiver at the University of Washington, largely responsible for the new calibration. He summarizes what the calibration does and how best to work with it.This paper is a guide to working with the Radiocarbon calibration issue in particular, as well as calibration curves in general. It therefore follows the conventions for calibrated and uncalibrated dates that are presented there, rather than ANTIQUITY's normal convention.
New evidence of ritual monuments at Long Meg and her Daughters, Cumbria

A note on Long Meg and her Daughters, the monolith and stone circle in Cumberland,provides excuse to quote both Stukeiey on the whole: ‘A great Celtic temple’; and Wordsworth on Long Meg herself: Speak Thou, whose massy strength and stature scorn The power of years - pre-eminent, and placed Apart, to overlook the circle vast Speak, Giant-Mother!More to the point, these new findings from air photography report new field monuments to with the standing circle and the second circle that Stukeley drew, and require a reappraisal of the Neolithic to Eariy Bronze Age monuments in Cumbria.
What future for Avebury?
Authors: Pitts Michael 
Published: January 2016

Towards the end of 1989, Lord Montagu of Beaulieu, Chairman of English Heritage, announced that detailed planning had started on a visitor centre at Stonehenge. For someone not touched by the generations of wrangling over this site, or spared the depressing squalor with which a visit deftly obliterates any preconceptions of mystery or romance, what could be more appropriate than good visitor facilities at one of the world’s top heritage attractions? What could be simpler to construct in an open landscape of not particularly valuable farmland?Of course, Stonehenge is not like that. This small group of standing stones by a road has provoked one of the most complex, bitter, and long-running archaeo-political stories of all time. It will run and run – make no doubt about that – but Lord Montagu’s announcement has a real significance for anyone with an interest in our past. Someone is actually trying to do something about the place.
Small-scale transport of early Neolithic pottery in the west Mediterranean
Authors: Barnett William K. 
Published: January 2016

The early Neolithic of the west Mediterranean
The archaeological complex known as the early Neolithic in the west Mediterranean represents the arrival of Neolithic traits in western Europe. Dating to around 5000 BC (Evin 1987), this complex is marked by the appearance of pottery, ground stone tools, and transvcrse projectile points. It continues for about a millennium until middle Neolithic villages, such as Villeneuve-Toulousane, begin to appear. The early Neolithic is characterized by a transitional agricultural subsistence economy. At Aude Valley cave sites, domesticated sheep first appear in aceramic Mesolithic layers with typical Tardenoisian tool assemblages and fauna (Geddes 1983). Examination of these sheep remains show that this strain originated in the Near East (Geddes 1985). Early Neolithic deposits (as defined by the presence of ceramics) are found at many of the same Mesolithic sites and contain similar lithic assemblages as well as a continuation of mixed hunted and domesticated fauna. The presumably novel open-air coastal sites of this period, such as Leucate-Corrège (Guilaine et al. 1984), also appear to represent a mixed economy. Since there is no sudden apparent shift in settlement pattern or economy associated with the early Neolithic, this period appears to be best characterized as a time of gradual transition from hunting and gathering to agriculture.
