Mesozoic Alkaline and related igneous rocks of Australia

Alkaline and related rocks are a relatively rare class of igneous rocks worldwide. Alkaline rocks encompass a wide range of rock types and are mineralogically and geochemically diverse. They are typically though to have been derived by generally small to very small degrees of partial melting of a wide range of mantle compositions. As such these rocks have the potential to convey considerable information on the evolution of the Earth’s mantle (asthenosphere and lithosphere), particularly the role of metasomatism which may have been important in their generation or to which such rocks may themselves have contributed. Such rocks, by their unique compositions and or enriched source protoliths, also have considerable metallogenic potential, e.g., diamonds, Th, U, Zr, Hf, Nb, Ta, REEs. It is evident that the geographic occurrences of many of these rock types are also important, and may relate to presence of old cratons, craton margins or major lithospheric breaks. Finally, many alkaline rocks also carry with them mantle xenoliths providing a snapshot of the lithospheric mantle composition at the time of their emplacement.
Accordingly, although alkaline and related rocks comprise only a volumetrically minor component of the geology of Australia, they are of considerable importance to studies of lithospheric composition, evolution and architecture and to helping constrain the temporal evolution of the lithosphere, as well as more directly to metallogenesis and mineralisation.
This contribution presents data on the distribution and geology of Australian alkaline and related rocks of Mesozoic age. The report and accompanying GIS document the distribution, age, lithology, mineralogy and other characteristics of these rocks (e.g., extrusive/intrusive, presence of mantle xenoliths, presence of diamonds), as well as references for data sources and descriptions. The report also reviews the nomenclature of alkaline rocks and classification procedures. GIS metadata are documented in the appendices.

Geological report on the Dundurrabin copper mine

The Dundurrabin copper prospect is 3.5 miles northwest of Dundurrabin sawmill and settlement, and 5 miles from Lyringham, which is connected by road to Grafton, Armidale and Dorrigo. The mine is favourably situated with regard to supplies of water and timber. Development consists of an adit to the lode with a cross-cut through it (Plate I), connected to a shaft from the surface on the south wall of the lode. The shaft has been sunk 30 feet below the adit with another cross-cut at that level through the formation. A few pits and costeans have been put down along the strike. Geology, prospects, and recommendations for further work are discussed.

Report on mica deposits on Yinnietharra and Bidgemia stations, Gascoyne River, Western Australia

The presence of muscovite on Yinnietharra Station in commercial sizes and qualities has been known since 1913, but little active development was carried out in the locality until 1926, when a syndicate, formed in England, took up leases and began operations. Activity lapsed the following year, but desultory prospecting more recently has led to the production of a few small cases of spotted mica, some of which was sold in Melbourne in the early part of 1942.  The deposits described hereunder are shown on the accompanying locality map, Plate 1. At this stage only brief references are made to deposits containing stained and spotted mica unsuitable for critical electrical or radio applications.

The geological evolution of the southern Taroom Trough and the overlying Surat Basin

Isopach, structure contour, and palaeo-geological maps illustrate the geological development of the southern Taroom Trough and the lower part of the Surat Basin sequence.
The meridional southern Taroom Trough, 50,000 km2 in area, is a southerly subsurface extension of the outcropping Bowen Basin. It is fault-bounded to the east and plunges northward. The maximum thickness of sedimentary fill increases northward from less than 400 m to 10,000 m, and consists of Lower Permian marine sediments, Upper Permian coal measures, Lower Triassic redbeds, and Middle Triassic stream sediments. The trough's present western margin is depositional, but the faulted eastern margin started to form in the Late Permian in the south and in the Early Triassic in the north; movement ceased in the Early Triassic in the south and in the Late Triassic in the north. Tectonic movements did not recur until Late Jurassic time.
Late Triassic erosion preceded deposition of Surat Basin sediments. These sediments extended over ever wider areas, even the basal sands spreading far beyond the Taroom Trough. The fully-developed Surat Basin is 300,000 km2 in area, and contains up to 2500 m of dominantly continental Jurassic sediments and dominantly marine Lower Cretaceous sediments. Lower Jurassic stream sediments (the main petroleum producers of the basin) are thickest and coarsest above the Taroom Trough, suggesting steady subsidence and compaction of the trough sediments.
By the Late Jurassic this compaction had virtually ceased, and epeirogenic uplift had given the basin its present shape, with the Mimosa Syncline (above the Taroom Trough) and the south-westerly-trending Dirranbandi Syncline (above a basement depression) being major structural features.
Petroleum, which is probably derived from both Permian and Jurassic sources, is most abundant in the Lower Jurassic sandstone on either side of the Mimosa Syncline. Some aspects of the migration and trapping of Permian petroleum are discussed, and it is suggested that the Lower Jurassic Hutton Sandstone in the virtually unexplored Bollon area could be prospective.

The geology of the Cobar mineral field and its bearing on prospecting

The Cobar mining field was examined between August, 1946 and June, 1947. Attention was concentrated on the operating mines, viz. New Occidental, New Cobar and Chesney. New Occidental Gold Mines, N.L. owns all three deposits and had requested assistance from the Commonwealth Government to search for new orebodies on their leases. It had previously been recognised that each of these orebodies lay close to a sharp contact between fine-grained and coarse-grained sediments. Of particular interest are the portions of the contact which have been subjected to minor folding, because, immediately to the south of these folds, fracturing favourable for ore localisation has developed. The geological examination was carried out in conjunction with the Geological Survey, Mines Department, New South Wales. Surface and detailed underground mapping were carried out. A preliminary magnetic survey of part of the field was carried out by the Geophysical Section during the first half of 1947. A special study of the New Cobar Mine and the plans of that deposit were made by Dallwitz, Fleischman and Ivanac.  This report provides a comprehensive overview of the situation, topography, history, structural geology and general geology of the area. Detailed descriptions are given of the history, workings, orebodies, and structure of each individual deposit. Various accompanying plans of the mines and the Cobar mineral field are included.

Terminology of lateritic profiles

During the last three years much work has been done on laterites in Northern Australia by geologists of the Bureau and in particular those attached to the North Australian Regional Survey. The co-operation of soils officers and geologists in this survey has led to a better understanding of the significance of laterites and of the zones within the profiles. Since several parties from the Bureau are now working in Northern Australia it seemed opportune to discuss the nomenclature of laterites and to suggest terms and definitions so that laterites can be described and mapped in the same way by the several field parties. With this object in view geologists from the Bureau and officers from the North Australian Regional Survey discussed the matter and the following terminology and definitions are circulated now for criticism within the Bureau.

The geology of the Nerrima Dome, Kimberley Division, Western Australia

Previous investigators in the area have interpreted the Nerrima Dome as a dome closed by folding (Wade, 1936), a dome closed against a transverse fault at the eastern end (Kraus, 1942), and as a westward plunging anticlinal fold probably closed by transverse faulting (Reeves, 1949). The purpose of the present survey is to determine by detailed geological mapping the true structure of the Nerrima Dome.
