内蒙古自治区三号店594高地钼矿点地质条件及物化探特征

Geological Conditions and Geophysical and Geochemical Characteristics of 594 Highland Molybdenum Deposit in No.3 Dian,Inner Mongolia Autonomous Region

通过对594高地的区域地质条件分析,包括地质背景、侵入岩岩性及接触关系、物探、化探、构造等方面;确定了矿体特征及找矿标志。钼矿体多发于在侵入体接触带部位,围岩蚀变主要有硅化、黄铁矿化等。硅化呈网脉状发育,黄铁矿化星点状分布于石英脉中或呈膜状、浸染状充填于硅化花岗岩裂隙面中;具高阻中高极化率特征,化探异常以Mo、Cu套合较好,浓集中心明显,异常呈条带状北西展布。

Based on the analysis of regional geological conditions of 594 highland,including geological background,lithology and contact relation of intrusive rocks,geophysical exploration,geochemical exploration and structure,etc.The ore body characteristics and prospecting criteria have been determined.Molybdenum ore bodies are mostly located in the contact zone of intrusive bodies,and wall rock alteration mainly includes silicification,pyritization,etc.Silicization develops in reticulate vein,pyritization stars are distributed in Shi Ying vein in dot form or filled in fissure surface of silicified granite in membranous and disseminated form.It has the characteristics of high resistance,medium and high polarizability.The geochemical anomalies are well nested with Mo and Cu,with obvious concentration centers,and the anomalies are distributed in a banded north-west pattern.
