| 摘 要： | 脉地田心铜矿床位于云南省漾濞县，是一个受断裂控制明显的小型铜矿床，矿体分布于白垩系下统景星组下段.矿体呈脉状产于灰白色中厚层状石英砂岩中，含矿岩石类型简单，以褪色蚀变砂岩为主.矿体规模为小型，矿石氧化率为73.61%~92.64%，属高氧化率矿石.初步推测矿床成因为与“滇西红层”中的层间断层构造蚀变带密切相关的沉积-热液改造型铜矿床.

| Abstract: | The small sized Maiditianxin copper deposit, located in Yangbi County, Yunnan Province, is mainly controlled by faults. The orebodies occur in the lower member of Jingxing Formation, Lower Cretaceous (K1j1). The ore veins are hosted in the medium-thick layered quartz sandstone, which is simply fading altered sandstone. The orebodies are small, with oxidation rate between 73.61% and 92.64%, belonging to high oxidation ore. By preliminary analysis, the genesis of the deposit is sedimentary-hydrothermal reformed type, closely related to the interbedded structural alteration zone in the "West Yunnan red beds". |
