摘要
个旧老卡岩体接触—凹陷带是个旧矿集区最重要的锡铜多金属成矿构造带,带中锡铜矿产资源十分丰富。带内锡铜矿体的成生与凹陷带构造密切相关,受构造、岩性和岩浆活动联合控制,凹陷带的形态、产状、规模的变化直接影响矿体的形态、产状、规模。凹陷带构造控矿正是由于其处在一个有利的位置,有一系列的配套及耦合因素的存在,最终在燕山晚期含矿岩浆气液作用下,形成富厚矿体。
GeJiu contact-depression zones of Laochang-Kafang rockbodies is famous for its huge Sn ,Cu reserves. The formation of Cu-Sn polymetallic ore deposits is commonly controlled by contact-depression structure, granite of Yanshanian orogeny and the strata and lithology. The contact-depression zones control the morphology of ore body and attitude,scale. As well as the complicatedly shaped basins, thoughs and concave areas on the granite tor are generally good places for the enrichment of skarn-sulfide deposits.
