| 中文摘要: |
| 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。凹陷带构造是一个有利成矿的构造部位,并配之有其他控矿因素,最终在燕山晚期含矿岩浆气液作用下形成富厚矿体。 |
| 英文摘要: |
| The contact-depression belt of Laoka granitic body is the most important Sn-Cu-polymetal ore-host structural.Sn-Cu ore bodies in the belt are genetically related to the belt and controlled by combination of structure,lithology and magmatism.Morphology,occurrence and size of ore bodies are directly influenced by the morphology,occurrence and size of the belt.The depression,a favorite orehost structure,together with other ore-control factors led to formation of thick and rich ore bodies under influence of late Yanshanian magmatic vapor-fluid. |
