| 摘 要： | 在金的伴生矿物中,黄铁矿在托里金矿床中是非常丰富的矿物。它不仅在数量上占优势,而且在本矿床中黄铁矿还以部分自然金的载体出现在矿化带中,所以对黄铁矿进行较为详细的研究是有实际意义的。另外,本矿床为一新型的金矿床——蛇绿岩型金矿,就其黄铁矿来说,无论是矿物学的特点或是地球化学特点都具有本类型矿床的独特性质,例如本黄铁矿中有CO/Ni<1、Au/Ag>1的特点。再者,托里金矿有两个成矿带,而黄铁矿在这两个成矿带中又有不同的特点,这是由于这两个成矿带不同的成矿环境所造成的。

| Abstract: | The gold deposits in the Toli ophiolite can be divided into Anqi and Sor-tohay ore belts. They differ from the other types of gold deposits in that the pyrite in them is characterized by Co/Nil.Pyrite in the former ore belt is rich in As but poor in Co and Ni, while that in the latter one is rich in Co and Ni but poor in As. The unit cell parameters of pyrite in the Anqi ore belt are larger than those of pyrite in the Sartohay ore belt. There is little difference between Mossbauer parameters of pyrite from the two belt and Mossbauer effect shows that, like other gold deposits the element Au does not enter the lattice of the pyrite. |
