Report presents the basic data and geochronological age interpretations for 89 K-Ar and 64 Rb-Sr isotopic analyses, made on metamorphic, granitic and volcanic rock samples derived from parts of the Musgrave Block visited by SADME geologists between...

TRONA EXPLORATION: Of the 9 rotary/diamond holes drilled, only the first, Meramangye 1, intersected a unit equivalent to the Observatory Hill Beds, which was the target horizon for trona. Drillholes Manya nos 2-6 and Marla 7 intersected Cambrian red...

Mintabie Opal Field With the increasing population at Mintabie there will be a greater demand for water, to the point where existing sources become inadequate. At present water supplies are obtained from three wells in the vicinity of the opalfield,...

The Pitjantjatjara Lands cover crystalline basement rocks of the Middle Proterozoic Musgrave Block, fringed by relatively unaltered sediments of the late Proterozoic and Palaeozoic Officer Basin, the late Palaeozoic Arckaringa Basin and the Mesozoic...

89 K-Ar and 64 Rb-Sr geochronological analyses of various selected samples of crystalline basement lithologies were made to date the major tectonic events of the Musgrave Block.

AIM:The 1974 Everard Seismic Survey consisted of a detailed grid of 103 km over the Munyarai prospect, and a regional tie line of 54 km with outcrops at the rim of the Officer Basin, to investigate the possibility of a prospective Ordovician sequence...

AIM: The MESA Wallatinna Seismic Survey was programmed to provide sufficient new data on the eastern Officer Basin, together with petrophysics and petroleum geochemical updates, to stimulate renewed interest and reduce exploration risk such that in...

Modern, multifold seismic data over the far eastern Officer Basin have been reinterpreted and seven reflectors mapped in time. Parts of six major structural zones are identified in the region: Munyarai Tough, Marla Overthrust Zone, Ammaroodinna...

Pronounced positive and negative geophysical anomalies on EVERARD represent the crystalline Musgrave Block in the north, a basement trough more than 4 km in depth that flanks the Musgrave Block to the south, and the crystalline Ammaroodinna Inlier to...

Seismic refraction and reflection work in the Wallatinna area in 1972 has suggested a fault along the north west edge of the Ammaroodinna inlier as the north west limit of Permian sedimentation, and thus of the Arckaringa basin. This is probably not...

The Musgrave Province is largely incorporated within the Anangu Pitjantjatjara Lands and includes cratonic crystalline middle Proterozoic basement rocks of the Musgrave Province proper, as well as mantling younger sedimentary rock successions...

The WINTINNA 1:250 000 mapsheet area lies between latitudes 27° to 28° South and longitudes 133°30’ to 135°00’ East. This ~16 400 square km area includes the Marla and Cadney Park settlements, and is crossed by the Stuart Highway and Adelaide to...

Large potential field anomalies can be observed in the Marla region of northern South Australia, and have been used to define the northern limit of the Gawler Craton. The subject project’s aim was to model the plausible source(s) for each of those...

A new generation, first edition WINTINNA 1:250 000 scale geological map and explanatory notes have been published. These documents represent the conclusion of the Geological Survey of South Australia's geological mapping program undertaken in the...
