【摘要】:本论文在在前人的研究基础之上,结合野外地质资料,从区域地质背景入手,重点分析研究区的矿区地质、矿体特征、矿石质量、蚀变分带等方面特征,根据工作部署本着保证重点,兼顾一般的原则,以评价库勒钼矿为主,兼顾外围的找矿工作,采用地质草测、化探工程、探矿工程、室内资料整理等方法,对地表矿化进行工程揭露,查证矿区及外围物化探异常,为控制矿区内已圈定矿体空间分布特征做出科学、系统的工作工作部署如下:(1)库勒钼矿矿区第一阶段:通过1∶5千及1:2千地质草(修)测,查明矿区的控矿地层,构造特征及其成矿的关系。以钻探为主要手段对南矿带深部已知矿体在走向上、倾向上进行深部控制,同时兼顾北矿带矿体的控制。进一步了解矿体产出特点及矿体与含矿斑岩体在空间上的相互关系。第二阶段:在第一阶段钻探成果基础上,进一步对已知矿体进行深部控制,大致查明矿体形态、产状、规模、厚度及品位变化情况做进一步了解。对矿体产出特征、控矿因素做进一步的了解,取得深入的认识,以更好地指导找矿。计划工作量:1:5千地质草修测17.5平方千米;1:2千地质修测2平方千米;槽探2000方;钻探3700米。(2)库勒钼矿区外围第一阶段:在勘查区内开展1:1万地质填图工作,在此基础上对1:2.5万化探异常采用1:1万土壤地球化学测量进行异常查证工作;第二阶段:在第一阶段的基础上,对发现的矿化蚀变带、及化探异常开展1:2千地质填图工作,选择成矿有利部位进行槽探钻探验证,以大致了解矿体空间分布规律,提出下一步工作建议。
[Abstract]:In this paper, on the basis of previous studies, combined with field geological data, starting from the regional geological background, focuses on the analysis of geological research area, orebody characteristics, ore quality, alteration zoning and other characteristics, according to the work plan according to ensure that key, taking into account the general principles to evaluate Cooley molybdenum, take into account the external the geological prospecting work, of1:25000soilgeochemistry, geochemical engineering, exploration engineering, indoor data processing methods of surface mineralization engineering verification revealed that the mine and the surrounding geophysical and geochemical anomaly, for the control of mining area has been delineated ore body spatial distribution characteristics of scientific work, system deployment is as follows: (1) the first stage of Cooley molybdenum deposit: through 1 to 5 thousand 1:2 and thousands of geological grass (repair), to identify the controlled strata in mining area, the relationship between structural characteristics and mineralization. The drilling as the main means of South ore belt of deep ore bodies in the known direction, The tendency of the deep control, at the same time to control the north belt orebody. To further understand the relationship between orebody characteristics and orebody and porphyry in space. The second stage: in the first stage based on the drilling results, further to the known ore body deep control, generally find out the orebody shape, occurrence, scale. The thickness and the grade of further understanding. On the orebody characteristics, ore controlling factors for further understanding, have deep understanding, to better guide the prospecting plan. Work: 1:5 geological survey of thousands of grass 17.5 square kilometers; 1:2 geological survey of thousands of 2 square kilometers; trenching 2000; drilling 3700 meters. (2) Cooley: the first stage in the peripheral areas of molybdenum ore exploration in 1:1 million geological mapping work area, on the basis of 1:2.5 and 1:1 by 000 geochemical anomaly of soil geochemical survey for anomaly verification work; in the second stage: Based on the stage of mineralization alteration found belt and geochemical anomalies in 1:2 1000 geological mapping, select parts of mineralization favorable trenching drilling verification, with a general understanding of space distribution law, put forward the suggestions for the next work.
