North Pilbara synthesis GIS

The North Pilbara project's main objective is to assist industry in their development off exploration strategies. In order to do this, we provide high-quality data sets such as this GIS, which provides different views of the same area, allowing correlation, comparison, and analysis at a broad scale across the entire North Pilbara.The advantage of this GIS is that it packages AGSO's primary data holdings for the entire region into a convenient digital package that can be manipulated and integrated with proprietary data in standard mapping applications. The North Pilbara GIS provides industry with a decision-making context, or wide-spaced framework. The lack of context is due the fact that industry commonly only have restricted data holdings over their leases. Therefore, regional synthesis data sets provide a context and framework for exploration decisions made on more spatially limited data.The North Pilbara GIS provides many new digital data sets, including a number of variations of the magnetics, gravity, and gamma-ray spectrometry. A solid geology map, and derivative maps, mineral deposits, geological events, and Landsat 5-TM provide additional views. This data set complements the 1:1.5 Million scale colour atlas (announced in June-July issue 58 of AusGeoNews).This provision of a regional digital data set will be an invaluable tool for exploration companies making comparative, correlative, and analytical decisions on the prospectivity of the North Pilbara. Just a few of the new aspects of the GIS include: -the under cover shape of prospective rocks with a new digital solid geology map; -all the images generated by the project (magnetics, gravity, Landsat, and radiometrics);-the imaging of several large shear zones, and complexity in granites;-compilation of geochemistry and geochronology;-a new chemical map based on radiometrics;-identification of the source regions of transported regolith
