| What is Geological Mapping? AGARSS geologists have
worldwide experience having carried out geological mapping at a range of scales and in a
range of geological settings. From the recent volcanic rocks of the Peruvian Andes to the
ancient Archaean rocks of the Australian Pilbara craton, AGARSS personnel have been active
in producing geological maps in support of mineral exploration. Inherent in the production
of accurate geological maps is the ability not only to recognise specific rock types but
also to develop a clear understanding of the geological evolution of an area and the often
complex relationships between one rock unit and another.
This involves not just mapping skills but also an in depth understanding of distinct
geological environments, stratigraphy, sedimentology, petrology, structural geology,
geochronology and geochemistry among many other aspects of the science.
