webmaster Posted December 26, 2004 Share Posted December 26, 2004 From: Mark J. Logsdon Subject: Cobaltite Colleagues working on a mining-related problem have asked me to help locate thermo data (with enough pedigree that one can sort out what they mean) for cobaltite. I appreciate (though probably not enough) that there are solid-solution issues in the Fe-Co-As-S system, so any guidance that anyone may have about how all this might be handled would be great. Any leads or suggestions would be most welcome. From: Dave Quirt Subject: Ni-Co-Fe-As-S system, tourmaline, and crandallite This request from Mark Logsdon has reminded me that I also need thermo data in several areas: (1) for the Ni-Co-Fe-As-S system (gersdorffite, rammelsbergite, safflorite, cobaltite, niccolite, etc.), particularly in the 150 to 250 deg C region, (2) for tourmaline-group minerals (specifically dravite), (3) for crandallite-group minerals (specifically goyazite).
