| 摘 要： | 辽东地区铅锌矿集中分布于辽东拗拉谷（辽东古裂谷）的中央裂陷区内。根据矿床地质背景,发现铅锌矿主要赋存于古元古宙辽河群高家峪岩组二岩段条带状含石墨大理岩、大石桥岩组一岩段条带状厚层含石墨大理岩、三岩段条带状白云石大理岩中。结合各矿床硫同位素、铅同位素和稀土元素特征,分析了成矿物质来源,建立了三阶段成矿模式,最后指出了今后...

| Abstract: | The lead-zinc is concentrated in eastern part of Liaoning Province, aulacogen （eastern part of Liaoning Province ancient rift） in the central rift zone. According to geological setting, it was discovered that the lead and zinc mainly occurred in the Paleoproterozoic Liaohe Group ,Gaojiayu rock group ,two banded marble containing graphite, Dashiqiao rock group a banded thick marble containing graphite, three banded dolomite marble. With the deposits of sulfur isotopes, lead isotopes and REE analysis of the forming material sources, established a three-stage mineralization pattern, and finally pointed out the direction for future exploration. |
