| Abstract: | Pyrites in Dianfang gold deposit of Proterozoic explosive breecia type are mainlygold-bearing minerals. Its crystal face symbol is measured as { 1OO } and belongs to sulfur-depletedtype (Fe1.0000 S1.8775-1.9821 ), Co /Ni > 1 (1. 5 - 5. 875 ). The conductivity of pyroelecticcoefficient is N type. The 34 S ranges from 4. 8% to 6. 8%. The formation conditions of pyritesis related to the magma mtrusive-volcanic eruption activities at Xionger era, and is in the opensystem, in generally, the temperature is higher, ranges from 22O to 438, the oxygenfugacity is high (logfo2 > -37 1O5Pa) and the sulfur fugacity is low (logs2 = - 39. 85 1O5 ~- 35. 65 l05Pa). The formation of the pyrite to plays an important role in marking andrecording the gold metallogenic processes of Proterosoic explosion breecia type. |
