福建政和夏山铅锌矿微量元素特征及矿床成因

本文主要论述：（１）方铅矿具有高含量的Ａｇ、Ｂｉ、Ｓｅ和高的Ｓｅ／Ｓ比值；闪铲矿富含Ｃｄ、Ｉｎ、 Ｆｅ，贫Ｇａ和Ｚｎ／Ｃｄ比值低的特点，黄铁矿中Ｃｏ／Ｎｉ比值大于１：这些特点都与国内外热液、矽卡 岩型铅锌矿相似．（２）花岗斑岩中成矿元素丰度高，而且元素组合情况与矿石中元素组合极相似， 反映它们的成因联系．

The Characterics of Trace Elements and Genesis of Xiashan Pb-Zn Deposit, Zhenghe, Fujign

Hereof mentions are chiefly made that in Zhenghe there are high contents of Ag, Bi, Se and Se/S ratio in galena; high contents of Cd, In, Fe and low content of Ga and low Zn/Cd ratio in sphalerite; Co / Ni>1 in pyrite. The characteristics of the above are in consistence with those of hydrothermal type and skarn type Pb-Zn deposits at home and abroad. There are high contents of ore elements in the granite porphyry; and the elements assemblages have stri- king similarities with those of the ores. Thus a genetical relationship is sug- gested between the both above.
