Abstract

The quantitative study of chemical composition of ten samples of the tetrahedrite group minerals from six deposits in Bolivia (Animas - Chocaya, Pulacayo, San Vicente, Machacamarca, Cerro Rico, Oruro) provided new data enabling their detailed classification within this group. The majority of samples are usual members of tetrahedrite group: tennantite-(Zn) (San Vicente, Oruro), tetrahedrite-(Zn) (Animas - Chocaya, Pulacayo, San Vicente, Cerro Rico, Oruro) and tetrahedrite-(Fe) (Pulacayo, Machacamarca, Cerro Rico). The recently redefined members of this group - argentotetrahedrite-(Fe) and kenoargentotetrahedrite-(Fe) were found in samples from Cerro Rico and Animas - Chocaya deposits, respectively. The descriptions and quantitative EPMA data for all studied samples are given in the paper.

玻利维亚矿床中四面体矿物的化学和分类

对玻利维亚6个矿床(Animas - Chocaya, Pulacayo, San Vicente, Machacamarca, Cerro Rico, Oruro)的10个四面体组矿物样品的化学成分进行了定量研究，提供了新的数据，使其能够在该组中进行详细分类。大多数样品是四面体组的常见成员:tennantite-(Zn) (San Vicente, Oruro)， tetrahedrite-(Zn) (Animas - Chocaya, Pulacayo, San Vicente, Cerro Rico, Oruro)和tetrahedrite-(Fe) (Pulacayo, Machacamarca, Cerro Rico)。最近重新定义的该组成员- argentotetrahedrite-(Fe)和kenoargentotetrahedrite-(Fe)分别在Cerro Rico和Animas - Chocaya矿床的样品中发现。本文给出了所有研究样品的描述和定量的EPMA数据。
