青海银灿——浪力克地区成矿地质条件及找矿前景分析

Metallogenic geological conditions and prospecting potential in the Eincan-Langlike area,Qinghai

青海省北祁连东段银灿——浪力克地区位于北祁连成矿带冷龙岭成矿亚带中段,属海相火山岩型铜多金属矿集区,区内火山、侵入活动强烈,中基性——中酸性火山岩广泛分布,已发现浪力克中型铜矿、银灿小型铜矿及曲麻沟铜矿点等多处铜矿床、矿(化)点。笔者通过深入研究区域成矿构造地质背景和区内成矿地质条件,总结区域成矿规律和区内主控矿因素,分析探讨了区内找矿前景,进而提出了新的找矿方向。

The Eincan-Langlike area is located in the central part of Lenglongling metallogenic sub zone within Northern Qilian metallogenic belt, which is marine volcanic type copper polymetallic ore concentration area.The volcanic and magmatic activities are in- tensive in the area, and intermediate basic and acidic volcanic rocks are widely distributed. Several copper deposits, mineralization oc- currences and spots were found in the region such as medium-sized Langlike copper deposit, small-sized Eincan copper deposit and Qumagou copper mineralization occurence. Through integrated study of regional metallogenic geological tectonic background and metal- logenic geological conditions, the regional metallogenic regularity and the main ore -controlling factors were summarized, prospecting prospects were analyzed and discussed, and then the new prospecting direction was proposed.
