摘    要:云南保山核桃坪铅锌多金属矿床的成因一直存在争议,本文通过电子探针分析对核桃坪铅锌多金属矿床主矿体1号矿体中的辉石进行分析并进行晶体化学计算认为核桃坪铅锌多金属矿床中的辉石主要以锰-铁次透辉石、铁次透辉石为主,个别为次透辉石及锰-钙铁辉石。将核桃坪铅锌多金属矿床中的辉石与国内一些典型的矽卡岩铅锌多金属矿床中的辉石矿物成分特征及Mn/Fe比值、Mg/Fe比值特征进行对比,认为核桃坪铅锌多金属矿床属接触交代型钙矽卡岩矿床,矿床纵向分带由地表至深部为Pb-Zn-Cu-Fe矽卡岩分带系列,矿床中的辉石含锰可认为是铅锌矿化的重要标志。

Abstract:The cause of Baoshan Hetaoping (Yunnan Province) lead-zinc polymetallic deposit has alwasys been in controversial. Electron microprobe analysis was conducted on pyroxene of No.1 orebody of the main orebody in Hetaoping lead-zinc polymetallic deposit, and crystal chemical calculations in this paper, which suggested that the pyroxene of this deposit is mainly consisted of manganese - iron diopsides and iron diopsides, while some individual is hypo-diopside and manganese - calcium and iron pyroxene. Comparison of pyroxene mineral composition characteristics and Mn / Fe ratio of Mg / Fe ratio between the Hetaoping polymetallic deposit and the typical skarn lead-zinc polymetallic deposits revealed that Hetaoping lead-zinc polymetallic deposit is a calcium skarn deposit of contact metasomatism. The vertical zone of the deposit from surface to deep is of Pb-Zn-Cu-Fe skarn series, and the pyroxene with manganese can be considered as an important indicator of lead-zinc mineralization.
