摘要
通过对黔西北地区铅锌矿中硫化物稀土元素组成特征、峨眉山玄武岩中成矿元素铅锌的含量、铅锌矿硫同位素及锶同位素组成分析表明,该区铅锌矿成矿物质不是来源于峨眉山玄武岩,由于峨眉山玄武岩的喷出时代与本区铅锌矿成矿时代相差较远,也不可能为本区铅锌矿的形成提供热源。
Analyses on characteristics of rare - earth elements composition within lead - zinc deposits in northwestern Guizhou, the lead -zinc contents of ore -forming elements within the Emeishan basalts and the constitution of sulfur isotopes and strontium isotopes show that minerogenetic materials havenl originated from Emeishan basalt, eruptive age of Emeishan basalts considerably differ from lead - zinc minerogenetic period, and also impossibly provide thermal source for formation of lead - zinc deposit.
