中文摘要: |
益克郭勒斑岩型钼矿床是近年来在东昆仑东段新发现的斑岩型矿床,笔者在地质研究的基础上,通过开展1∶10000地面高精度磁法测量,在研究区内圈出3处低磁异常。依据地质勘查成果,结合磁物性特征研究对比分析,认为C1、C2磁异常与成矿斑岩体及斑岩成矿作用有关,C3异常由构造引起;对斑岩型矿床成矿条件较好的C2低磁异常区开展1∶10000激电中梯剖面测量,圈出激电异常带2条;对磁、电异常套合好的地面高精度磁测线进行2.5维反演,结合地质解译,选择成矿有利地段进行深部验证,圈出隐伏钼矿体6条,查明了低磁异常套合的激电异常由斑岩矿及斑岩成矿作用引起,并总结了研究区斑岩型钼矿综合找矿模型;发现了明显的地质、地球物理找矿标志,具有较好找矿前景。 |
英文摘要: |
Yikeguole porphyry molybdenum deposit is a newly discovered porphyry molybdenum deposit in the eastern part of East Kunlun in recent years. Based on geological research, the author conducted 1∶10000 ground high-precision magnetic survey, and identified three low magnetic anomalies in the study area. According to geological exploration results and combined with the comparative analysis of magnetic physical characteristics, It is considered that C1 and C2 magnetic anomalies are related to porphyry and porphyry mineralization, and C3 anomaly is caused by structure. 1∶10000 IP profile survey was carried out for C2 low magnetic anomaly area with better metallogenic conditions of porphyry deposits, and two IP anomaly zones were identified. Of magnetic, electric anomaly set us a good ground for high precision magnetic survey line 2.5 d inversion, combined with the geological interpretation, choose the favorable area for verification in the depth, the circle of concealed 6 molybdenum orebody, find out the low magnetic anomaly sets IP anomalies caused by porphyry deposits and porphyry mineralization, and sums up the comprehensive prospecting model of porphyry molybdenum mine in the study area. Obvious geological and geophysical prospecting signs have been found, which has great prospecting prospects. |
