Spreadsheet containing descriptions of rock thin sections collected from the Southern Prince Charles Mountains by AGSO geologists in the 1970s

Excel spreadsheet summarising thin sectioned samples collected from the Southern Prince Charles Mountains in the 1970's by Geoscience Australia geologists. Each sample is briefly described by fields identifying primary and secondary mineral abundance. The most common primary mineral is ID by 1.1, the second most common mineral by 1.2, and so on. Similarly, secondary minerals are ID by 2.1, 2.2 etc. Secondary minerals can be those formed by either alteration or later metamorphic events.

This spreadsheet was to form the basis for an interactive GIS summarising the petrology of the Prince Charles Mountains. A similar project had been undertaken by the author for a Metallogenic Atlas of the Pine Creek Region in the Northern Territory, Australia (refer Geoscience Australia).

Thin Sections are held at Geoscience Australia.
