Rapid fluid inclusion data
for exploration (decrepitation)
Decrepitation is usually extremely intense, but at unusually high temperatures given the typically low formation temperature of calcite.
This sample is from the Bou Jaber mine in Tunisia, a small,
hosted karst breccia with Pb, Zn, F and Ba mineralization. Fluid
homogenization data in barite and fluorite indicate a formation
of 90-120 C from hydrocarbon rich source fluids. Calcite and other
have decrepitation peaks ranging from 400 to 800 C which do not reflect
