Welcome to Sirius Exploration Geochemistry. Sub-disciplines active in the department embody biogeochemistry, organic geochemistry, hint and elemental geochemistry, and metamorphic and igneous-rock geochemistry. Leucite could be very uncommon in plutonic lots; many minerals have particular peculiarities in microscopic character according to whether they crystallized in depth or near the surface, e.g., hypersthene, orthoclase, quartz.
There are some curious instances of rocks having the same chemical composition, however consisting of totally completely different minerals, e.g., the hornblendite of Gran, in Norway, which comprises only hornblende, has the same composition as a few of the camptonites of the same locality that include feldspar and hornblende of a special variety.
Understanding the chemical composition of rocks tells oil firms the place to drill for oil; allows scientists to place collectively broad-based mostly theories about the way the Earth is changing; helps environmental administration corporations decide find out how to get rid of a poisonous or hazardous substance; and steers mining corporations toward use of natural sources with a minimum environmental affect.
The IAGC Works with fascinated teams in planning symposia and different types of conferences associated to geochemistry. Xiangzhao Kong is at the moment a senior scientist in Geothermal Vitality and Geofluids (GEG) Group within the Institute of Geophysics, ETH Zurich, Switzerland.
