| Abstract: | The pyrite thermal electricity have been used to explorat endogenic An deposite to get much advantage, but there are different conclusions about it by different geologists for individual deposit. The authors simulated the condition of An ore forming to test synthetic pyrite crystals of various features and to discuss the thermal electricity and composition of pyrite influenced by physicochemical condition during pyrite forming and also to reveal the evolution regular of pyrite thermal eletricity with various ratio of Fe/S and As.Co.Ni. In the end a general review has been given to the pyrite thermal electricity applied in explorating An ore. |
