摘要
云南建水县垄得铅锌矿体赋存于断层构造破碎带中,构造控矿明显。矿体底板为下二叠统茅口组(P_1m)灰岩,矿体顶板为中二叠统峨眉山组(P_2e)玄武质角砾岩。从同位素资料看,矿体主要形成于华力西期-印支期,属与中、晚二叠纪玄武岩浆有关的热液型矿床。
The orebody of Longde Pb-Zn deposit in Jianshui,Yunnan is in the fault Fracture zone,ore control of structure clear.The bottom of orebody is Lower Permian Maokou Formation(P1m )limestone,whereas the top Middle Permian Emeishan Formation(P2e )basaltic breccia.According to the isotopic data,the orebody is formed mainly in Variscan-Indosinian,belonging to the hydrothermal deposit related to Middle,Late Permian basaltic magmatism.
