Pyrite is the most common sulphide in the Earth’s crust and occurs in many different types of rock. Following many decades of research, the morphology, trace element and isotopic composition of pyrite can be used to reconstruct a range of bio- and geological processes across a broad spectrum of scales.
In the oceans, pyrite is the dominant sink for reduced sulphur and is intimately connected to biological pathways of sulphate reduction, meaning the formation and isotopic composition of pyrite can be used to reconstruct the redox architecture of ancient marine environments. As a major gangue mineral phase in hydrothermal ore deposits, the formation and geochemistry of pyrite can be used to investigate and potentially detect ore forming processes. At the other end of the life-cycle, the weathering of pyrite during acid mine drainage and subsurface geological storage is a major environmental concern.
This session will bring together scientists investigating pyrite across a range of physico-bio-geochemical conditions in various earth science disciplines e.g. nuclear waste, ore deposits or acid mine drainage. Our aim is to foster intradisciplinary knowledge transfer of experiences between different research areas. We invite contributions presenting geochemical field studies, in-situ and laboratory investigations of rocks and formations as well as numerical simulation studies within the given context.
