Recently, my deposit study has found that fluid boiling and immiscibility respectively occurred in two metallogenic stages. It is a hydrothermal deposit. The fluid inclusions host in quartz, calcite, and beryl, and these minerals were sampled from pegmatite veins and quartz veins.
(1) For the boiling NaCl-H2O fluid, these aqueous inclusions show separate salinity value (8~10 and 18~20 wt% NaCl equiv.). Should I choose the relatively high or low salinity inclusion for pressure calculation?
(2) For the CO2-H2O-NaCl system, I cannot find pure CO2 inclusions, and there are mainly multiphase fluid inclusions. To calculate the pressure of immiscible fluid, I downloaded the software Flincor, but it can only run under Windows XP, is there any other better method? A diagram or software?
(3) Moreover, how to choose the lithostatic or hydrostatic conditions for the correction of ore pressure and depth?
Thank you!
1. For pressure calculation you can select high saline fluids.
2. You can download bakker program in internet otherwise send email to professor bakker. He will give you no problems.
3.
you never say what kind of deposit type you are working on, but you should. In seafloor systems, there is only the depth of the overlying water column (but no pressure correction if phase separation observed). In other deposit types, you obviously can have lithostatic load to correct for.
Thank you for your answer. I have now revised my question.@ Jan Matthias Peter
