Seismic veolocity survey in Rough Range No 1 Well, Western Australia

At the request of West Australian Petroleum Pty, Ltd, and the Department of Mines, Western Australia, the Bureau carried out a seismic velocity survey in Rough Range No.1 Well, with the object of obtaining velocity distribution data for use in the interpretation of results of seismic refraction surveys in the area. Twenty-two shots were fired from a shot point about 1 000 feet from the well, Geophone depths in the wed ranged from 2,000 feet to 14,000 feet, usually at intervals of 500 feet, but the intervals were varied at points where there was a significant change in the stratigraphy, Recordings from 16 of the shots were used in the calculations. Results indicated that, as would be expected, the hard crystalline limestone which comprises the top 700 feet of section has a much higher velocity than the clastic limestones which underlie it. An abrupt velocity change from 7,100 ft/sec. to 12,600 ft/sec at 3,250 feet corresponds approximately with the change from Windalia Radiolarite to Muderong shale, and also with a density change from 2.1 to 2.4. A second major velocity change from 12,600ft/sec. to 16,500 ft/sec. at 6,800 feet also corresponds approximately with a density change from 2.5 to 2.7. An abnormal increase in velocity recorded at about 9,000 feet must be considered as very doubtful and velocities at this depth have been averaged.

Geophysical work at Macquarie Island, April 1952 - April 1953

1952-3 was the third successive year of geophysical work at Macquarie Island. During the previous year Mr. W.H. Oldham was mainly concerned with the preparation of the establishment for future operation as an observatory. This record outlines how, as a consequence, 1952-53 was devoted to full-time technical proceedings in both geomagnetism and seismology. It does not present the results of the scientific observations in full. These will be presented in a further report, but it does give in tabulated form absolute magnetic values observed and seismic phases recorded.

The Yeuralba Mineral Field, Northern Territory

A geological investigation of the Yeuralba mineral field was undertaken by the Bureau of Mineral resources as part of the field activities for the 1952 field season. Actual field work occupied five weeks in August and September. Most of this time was devoted to sampling individual greisen occurrences. In addition, a geological map of Yeuralba and the surrounding area was prepared on a scale of 1:25,000. Sandstones and tuffaceous sandstones of Lower Proterozoic age have been folded and intruded by porphyry, epidiorite, and granite, in the Yeuralba area. The granite intrusion was followed by a strong tensional movement and a regional system of black faults and strong joints was developed. Lower Cretaceous sandstone and porcellanite unconformably overlie the igneous rocks and Lower Proterozoic metamorphics. The granite has been hydrothermally altered to a marked degree along these fractures. Tin, tungsten, gold and bismuth mineralization is associated with greisen, tourmalite, topazite, and other alteration products of the granite. Cassiterite-bearing tourmalites and assiterite-wolframite-gold-bearing topazites and tourmalites occur within the granites mass and wolframite-scheelite-bismuth-bearing greisens at the contact between the granite and the sediments.  Bulk sampling and preliminary grab sampling of a number of these bodies indicates that several of the bodies should be tested in a more detailed manner, to determine whether they will bulk at a grade which would permit economic mining of the deposits.

Radioactive surveys, Katherine - Darwin area, Northern Territory: summary of activities 1st January to 30th June, 1953

Surveys and investigations associated with the search for uranium deposits were confined mainly to the Darwin-Katherine region of the Northern Territory. Other surveys included - (1) Aero scintillometer survey of part of the Radium Hill area for the South Australian Government; (2) Test flights and surveys with a scintillometer mounted in a helicopter. The results of the airborne surveys at Radium Hill were given to the South Australian Department of Mines in the form of anomalies marked on aerial photographs. It is understood that that Department is preparing and issuing a map showing the anomalies. The results of the tests with the helicopter have already been issued in a separate report entitled - "Records 1953 No. 106 - Radioactive Surveying from a Helicopter" by J. Daly. The remainder of this progress report will be devoted to the search in the Darwin-Katherine district.

Seismic reflection survey, Darriman, Gippsland, Victoria

A seismic reflection survey was carried out in the Parish of Darriman, Victoria. The survey was planned to investigate a gravity anomaly, which may be an indication of a structure within the sedimentary section favourable to the accumulation of oil or natural gas. For the most part reflections were exceptionally good, and it was possible to trace one reflecting layer over most of the area. Contouring showed the presence of an anticlinal structure, plunging to the east, but rising and broadening to the west. On the flat crest of the structure, there is probable closure in two places. The thickness of the Tertiary sediments may be a maximum of 6,000 feet, but may be only 3,000 feet on the crest of the structure and 4,000 feet on the flanks.

Preliminary report on the petrology and petrography of limestones from the Fitzroy Basin

This preliminary report deals with examination and classification of Ordovician, Middle and Upper Devonian limestone samples collected in the Fitzroy Basin during August, September and October of 1953. The geology of the area has recently been described by Guppy (1953). Rocks are designated by their field numbers, as geologists of West Australian Petroleum Limited, in conjunction with whom the collection was made, have retained the numbers for reference. For purposes of petrographic discussion, the nomenclature of clastic limestones as set out by Condon (1953) is used. Basic information sought in investigations of most limestones concerns: 1) Composition: distinction between calcite and dolomite is important; [and] 2) Origin: the origin of many limestones is very complex, but division into clastic, organic or chemical limestone should be attempted. Texture, both as observed under the microscope and in handspecimens is very useful, but in some cases (especially bioherms) field evidence supplies the only criterion. This paper has two main sections. The section on determination of composition describes techniques for distinction between calcite and dolomite, and the section on description of specimens incorporates suggestions about origin and environment of deposition where these logically arise from examination of textural or other features. 78 thin sections were examined, and textures typical of limestones of the area are illustrated by photomicrographs.

Open cut coal programme - Newcastle region, Point Morisset area Drilling results

A total of 25 rotary cored holes were drilled by the Bureau in Portion 49, Parish of Wallarah, County Northumberland, 2 miles south of Swansea. Approximately 1400 ft. of "test and define" drilling proved a possible 200,000 tons of coal suitable to be open cut under an average overburden of 6/1 ratio. The initial drilling programme showed a rolling seam. After surveying, further holes were drilled to locate the displacement which is 10 to 15 ft. in the S.W. corner of the area. No other obstacles are known which would hinder immediate working of the area. The lower split of the Wallarah Seam was tested in three holes but was found to be too thin to warrant further prospecting. The geology of the area is discussed in this report, and the results of the drilling programme are shown in the accompanying graphic and bore logs.

Some observations on laterites in the Northern Territory

In the Northern Territory laterites are formed in situ as: (i) an illuvial soil horizon; and (ii) a chemical lake laterite deposit. The end product of extensive weathering processes of certain favourable beds is considered by some to be a true mature laterite, whereas others believe it is merely a duricrust. The denudation of laterite and transportation, deposition and cementation of the fragments with other rock fragments result in a detrital laterite deposit. Water-rounded rock fragments in the detrital laterites are readily coated and cemented with iron oxides and resemble the pisolites in the ferruginous zone of the lateritic profile. This similarity results in an exaggeration of the true extent of laterization. The similarity in environmental conditions between the process of precipitation of uranium minerals and laterization is discussed. True mature and detrital laterites are illustrated by photographs.

Preliminary report on investigation volcanic activity, Umboi Island, New Guinea

On the 9th January, 1953, the writer received a letter from the Rev. Knoller of the Lutheran Mission, Umboi, describing some recently discovered thermal areas. Permission was requested and obtained from the Government Secretary, Port Moresby, to proceed to Umboi and investigate these areas. During the investigations all six thermal areas known to the inhabitants, both European and Native, were visited. These six areas are disposed about Mt. Talo, a well defined volcanic cone containing two crater lakes and located somewhat northwest of the centre of the island. These thermal areas have been numbered i to vi in the order in which they were visited.

Seismic survey of the Nerrima Dome, Kimberley Division, Western Australia

This report contains the results of a seismic survey on the Nerrima Dome, a major structure within the Fitzroy Basin and near its south-western boundary. The dome is situated near the Fitzroy River about 100 miles south-east of Derby in the West Kimberley district of Western Australia. The Nerrima Dome has been mapped at the surface in Permian sediments and is a complex structure. It was desired to determine if the dome existed at depth and, if not, the structure at depth, with a view to locating a site for a deep drilling test. The target beds for such a test are Devonian and/or Ordovician sediments over which the Permian sediments are believed to lie unconformably. Reflection methods were tried and proved unsuccessful and the survey was carried out using refraction methods. Although the structure underlying the dome has not been clearly shown, the refraction method has indicated that it is complex and does not conform with the domal structure at the surface. There appears to be a major unconformity at comparatively shallow depth (2000 ft). The deep structure (7000 ft) although apparently less complex than that immediately below the unconformity, also bears no obvious relation to structure at surface. The results so far obtained are reasonably conclusive in showing that no simple dome-like structure of large magnitude exists under the Nerrima Dome.

Preliminary report of Permian brachiopod faunas of the Fitzroy Basin

The following report is a brief preliminary outline of the Permian brachiopod faunas of the Fitzroy Basin. The collections have all been made by the Kimberley geological survey party of the Bureau of Mineral Resources from 1948 to 1952. Unfortunately many of the specimens determined or discussed in this report have been destroyed or damaged in the fire at the Bureau offices. The determinations must be regarded as provisional for some forms, as sufficient work has not yet been done, and further collecting is necessary to deal satisfactorily with others, apart from the damage sustained in the fire. As will ensue below many forms are new. It is hoped to describe them systematically from the new collections made in 1953. Some will be passed over to outside specialists. Direct comparison has been made with Carnarvon Basin collections. There is no attempt at description in this report. The collections will be treated under formation names beginning with the lowest. A discussion of ecology is being reserved until later.

Geoscience Australia Sentinel-2A MSI NBART Collection 3 - DEA Surface Reflectance NBART (Sentinel-2A MSI)

Background:
This is a sub-product of DEA Surface Reflectance (Sentinel-2A MSI) - Geoscience Australia Sentinel-2A MSI Analysis Ready Data Collection 3. See the parent product for more information.

Reflectance data at top of atmosphere (TOA) collected by Sentinel-2A MSI sensors can be affected by atmospheric conditions, sun position, sensor view angle, surface slope and surface aspect.

Surfaces with varying terrain can introduce inconsistencies to optical satellite images through irradiance and bidirectional reflectance distribution function (BRDF) effects. For example, slopes facing the sun appear brighter compared with those facing away from the sun. Likewise, many surfaces on Earth are anisotropic in nature, so the signal picked up by a satellite sensor may differ depending on the sensor’s position.

These need to be reduced or removed to ensure the data is consistent and can be compared over time.

What this product offers:
This product takes Sentinel-2A MSI imagery captured over the Australian continent and corrects the inconsistencies across the land and coastal fringe. It achieves this using Nadir corrected Bi-directional reflectance distribution function Adjusted Reflectance (NBAR).

In addition, this product applies terrain illumination correction to correct for varying terrain.

The resolution is a 10/20/60 m grid based on the the ESA level 1C archive.

Applications:
- The development of derivative products to monitor land, inland waterways and coastal features, such as:
               -  urban growth
               -  coastal habitats
               -  mining activities
               -  agricultural activity (e.g. pastoral, irrigated cropping, rain-fed cropping)
               -  water extent
- The development of refined information products, such as:
               -  areal units of detected surface water
               -  areal units of deforestation
               -  yield predictions of agricultural parcels
- Compliance surveys
- Emergency management
