| 中文摘要: |
| 河南卢氏伟晶岩型锂成矿带位于东秦岭造山带灰池子岩体北侧的元古界地层中。成矿带中已发现锂矿床4处,矿脉走向以NE向为主,其次为NW向,矿石类型以锂辉石、锂云母型花岗伟晶岩为主,围岩主要为秦岭岩群与峡河岩群的黑云石英片岩、斜长角闪岩及大理岩等。本文对成矿带成因、找矿标志、找矿潜力等方面进行了分析研究,结果表明:该成矿带成矿时代为晚志留世至早泥盆世,其产出受到灰池子岩体与朱-夏断裂带的控制,伟晶岩脉中的锂辉石、锂云母为直接找矿标志;结合该区锂矿床成矿地质特征、锂化探异常,圈定了2处找矿潜力区。 |

| The Lushi pegmatite-type lithium metallogenic belt in Henan province is located in the Proterozoic strata on the north side of the Huichizi intrusion in the East Qinling orogenic belt. In the metallogenic belt four lithium deposits have been found. The ore veins trend mainly NE then NW. The ore is dominated by spodumene and lipolite granite pegmatite type and generally hosted by biotite-quartz schist, plagioclase amphibolite and marble of Qinling rock group and Xiahe rock group. This paper focus on study and analysis of genesis, prospecting mark and prospecting potential of the metallogenic belt. The belt is controlled by Huichizi intrusion and Zhu-Xia fault zone. The metallogenic duration is from late Silurian to early Devonian. Spodumene and lepidolite in pegmatite dike are the direct prospecting mark. According to the metallogenic geological characteristics and geochemical anomalies in this area, two prospecting potential areas have been delineated for further prospecting. |
