摘要
近年来采用黄铁矿热电性质特征寻找内生金矿床取得很大进展,但在具体矿床 应用中,不同学者有不同认识和结论。作者通过实验矿物学的研究方法,模拟金矿床形成的物 理化学条件,实验合成各种特征的黄铁矿晶体,深入探讨黄铁矿形成时物理化学条件对黄铁矿 的化学组成及热电性质的影响程度。论述黄铁矿热电性质及其矿物的铁硫比值及As、Co、Ni含 量变化的演变规律,对利用黄铁矿热电性质找金应用进行综合评述。
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.
