Australia magnetic dykes map

This map contains information on Oil and Gas pipeline infrastructure. Attributes have been added to comply with data standards and minor coding of line work has been achieved using annotation from the map. Further data has been added, specifically for the specific Acreage Release Areas.

The Hydrologeology Map of Australia defines the sedimentary basins and fractured rock provinces which make up the regional hydrogeological divisions in Australia. These hydrogeological provinces have been further classed with regard to either a fractured rock province or a sedimentary basin, distribution of aquifers within the province, and aquifer productivity.

This map shows the distribution and age of major stratigraphic, intrusive and medium- to high-grade metamorphic units of onshore Australia. Units on the map represent stratigraphic supergroups, regional intrusive associations and regional metamorphic complexes.

Geoscience Australia and the National Oceans Office carried out a joint project to produce a consistent, high-quality 9 arc second (0.0025° or ~250m at the equator) bathymetric data grid of those parts of the Australian water column jurisdiction lying between 92º E and 172º E and 8 º S and 60º S. As well as the waters adjacent the continent of Australia and Tasmania, the area selected also covers the area of water column jurisdiction surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. The area selected does not include Australia's marine jurisdiction off the Territory of Heard and McDonald Islands and the Australian Antarctic Territory.

A geotechnical landscape map of Australia has been drawn depicting regions of constant [geological and physical] (NOT geophysical {Ed}) properties for road construction. The map, drawn at a scale of 1:2 500 000 for clarity, has a true accuracy of a 1:5 000 000 scale map, and is based on the four variables - landform, underlying lithology, soil type and [surficial] lithology - which are the principal [geological and physical] determinants for road construction. The origins and interpretation of the source maps together with a description of the legend of the geotechnical landscape map are described in this Report. Precis {Ed}: A map delineating regions with differing geotechical properties with particular application to road construction.

These maps were made initially for the PDAC 2001 International Convention. They have been published and made available via the web. There are two maps for each of the following commodities (gold, nickel, lead-zinc and copper). The first map depicts Australia's mineral occurrence locations, deposits, potential rock units and geological regions with the mineral occurrence density grid, while the second map provides an infrastructure theme and the mineral occurrence density grid. Infrastructure includes roads, railways and pipelines.
