Abstract

The concentrations of trace elements in pyrite from blocks 8, 19-SE, 19-NW, 19-NE, 19-SW, 103-W, 103-E, 144, 146, 147, 149-south, 150, and 151 of copper-gold high sulphidation Chelopech deposit were determined by LA-ICP-MS. It was found that the pyrites from the individual blocks are enriched in different degrees of “impurity” elements: the highest contents of Ag, Au, Zn, Hg, and In are typical to block 19-NE; Se, Bi, and Ti to block 19-SE; As, Mn, Tl, V, and Cd to block 19-SW; Co and Ni to block 144; Sb and Sn to block 146; Cu to block 149-south; Pb, Te, and Ga to block 103-E and Cr to block 103-W. The obtained results also show that in collomorhic pyrites the variations in the contents of trace elements are always very large and are rather due to adsorption processes than isomorphism. In addition, pyrites are also enriched in poisonous trace elements, especially from the lower level of the northern blocks, which, however, also have the highest values of gold and silver.

Chelopech矿床矿物地球化学:1 .黄铁矿中的微量元素

采用LA-ICP-MS测定了铜金高硫化Chelopech矿床8、19-SE、19-NW、19-NE、19-SW、103-W、103-E、144、146、147、149-south、150和151区块黄铁矿中微量元素的含量。结果表明，各块体黄铁矿中均富含不同程度的“杂质”元素，其中Ag、Au、Zn、Hg和in的含量最高，是典型的19-NE块体;Se、Bi、Ti阻断19-SE;As、Mn、Tl、V、Cd阻断19-SW;Co和Ni到144块;Sb和Sn阻挡146;Cu要封锁149-south;Pb、Te和Ga用于阻挡103-E, Cr用于阻挡103-W。结果还表明，在黄铁矿中，微量元素的含量变化总是非常大，这主要是由于吸附过程而不是同构作用。此外，黄铁矿中还富含有毒微量元素，特别是北部块体下部，但金、银的含量也最高。
