多元素分析在岩性及含矿性判别的应用——以塞尔维亚佩吉铜金矿床为例

塞尔维亚佩吉铜金矿床位于世界著名的特提斯欧亚成矿带西端的Timok岩浆杂岩带南部.该矿床由上部高硫型铜金矿化和下部斑岩型铜金矿化组成,矿化主要赋存在下部安山岩中.文章通过分析岩石多元素地球化学特征,并结合地质编录,认为下部安山岩并非单一岩性,而是由三种不同的岩性组合而成.其中LA-2系列安山岩是主要的赋矿围岩,具有高V...

Application of multielement in the Identification of lithology and ore-bearing feature: take the Cukaru Peki Copper-Gold deposit in Serbia as an example

Cukaru Peki Copper-gold deposit is located in the south of the Timok magmatic complex at the western end of the world-renowned Tethyan Eurasian metallogenic belt. The deposit comprises an upper high-sul.dation mineralization zone and an underlying porphyry-style mineralization zone. The orebody occurs mainly in the lower andesite unit. The lower andesite unit may be composed of three di.erent sub-units according to the multi-element geochemical characteristics and geological logging of the rocks. The characteristics of the main ore-bearing rock unit LA-2 are high V/Sc, low Sc and high Sr, low Y,and high Sr/Y ratio, which indicates a copper-rich porphyry magma source, and a close relationship between the magma and the cooper-gold mineralization in this region. The analysis of multi-element geochemical characteristics can provide reference for the identi.cation of lithology and ore-bearing property of volcanic strata.
