Geocheminar winter-2015

Fluid and melt inclusions are small aliquots of fluid trapped by minerals during growth in a variety of geological settings from ocean basin to the asteroid belt out into the space. Ideally, the host mineral acts as a protecting capsule from the external chemical/physical variations, and thus, fluid and melt inclusions can track the geochemical evolution of a rock prior to its formation. Since the first description of fluid and melt inclusions by Sorby (1858), many researchers have applied the fluid and melt inclusion technique to answer geological relevant questions. For this Geocheminar, I will review the basis of the petrography and the microthermometry analyses based on fluid and melt inclusions.
