| 摘 要： | 曹四夭钼矿床位于华北地台北缘内蒙古台隆凉城断隆东部。钼矿体主要赋存于曹四夭花岗斑岩外接触带的集宁群黄土窑组浅粒岩、变粒岩中,燕山期中酸性岩浆侵入活动与成矿关系密切。初步估算钼金属量为176万t。笔者在分析曹四夭钼矿成矿地质背景、矿体地质特征、物化探异常特征等基础上,提出了该矿床成因为具"二元结构"的斑岩型钼矿床,并进一步总结了找矿标志。

| Abstract: | Caosiyao Mo deposit was located in eastern Liangcheng fault uplift of Inner Mongolia platform uplift belonging to the northern margin of North China platform.The molybdenum ore bodies mainly occurred in leucoleptite and granulite of Huangtuyao Formation in Jining Group,contacting the Caosiyao granite porphyry.The acidic magma intrusive activity in Yanshan period had close relationship with mineralization,and the preliminary estimate of molybdenum metal amount was 1760 000 t.Based on the analysis of ore-forming geological background,geological characteristics of ore body,and the geophysical and geochemical anomalies,of the Caosiyao Mo deposit,the authors consider that the deposit had dual structure in type,and further summarized the prospecting indicators. |
