【摘要】：本論文在在前人的研究基礎(chǔ)之上,結(jié)合野外地質(zhì)資料,從區(qū)域地質(zhì)背景入手,重點(diǎn)分析研究區(qū)的礦區(qū)地質(zhì)、礦體特征、礦石質(zhì)量、蝕變分帶等方面特征,根據(jù)工作部署本著保證重點(diǎn),兼顧一般的原則,以評(píng)價(jià)庫勒鉬礦為主,兼顧外圍的找礦工作,采用地質(zhì)草測(cè)、化探工程、探礦工程、室內(nèi)資料整理等方法,對(duì)地表礦化進(jìn)行工程揭露,查證礦區(qū)及外圍物化探異常,為控制礦區(qū)內(nèi)已圈定礦體空間分布特征做出科學(xué)、系統(tǒng)的工作工作部署如下:(1)庫勒鉬礦礦區(qū)第一階段:通過1∶5千及1:2千地質(zhì)草(修)測(cè),查明礦區(qū)的控礦地層,構(gòu)造特征及其成礦的關(guān)系。以鉆探為主要手段對(duì)南礦帶深部已知礦體在走向上、傾向上進(jìn)行深部控制,同時(shí)兼顧北礦帶礦體的控制。進(jìn)一步了解礦體產(chǎn)出特點(diǎn)及礦體與含礦斑巖體在空間上的相互關(guān)系。第二階段:在第一階段鉆探成果基礎(chǔ)上,進(jìn)一步對(duì)已知礦體進(jìn)行深部控制,大致查明礦體形態(tài)、產(chǎn)狀、規(guī)模、厚度及品位變化情況做進(jìn)一步了解。對(duì)礦體產(chǎn)出特征、控礦因素做進(jìn)一步的了解,取得深入的認(rèn)識(shí),以更好地指導(dǎo)找礦。計(jì)劃工作量:1:5千地質(zhì)草修測(cè)17.5平方千米;1:2千地質(zhì)修測(cè)2平方千米;槽探2000方;鉆探3700米。(2)庫勒鉬礦區(qū)外圍第一階段:在勘查區(qū)內(nèi)開展1:1萬地質(zhì)填圖工作,在此基礎(chǔ)上對(duì)1:2.5萬化探異常采用1:1萬土壤地球化學(xué)測(cè)量進(jìn)行異常查證工作;第二階段:在第一階段的基礎(chǔ)上,對(duì)發(fā)現(xiàn)的礦化蝕變帶、及化探異常開展1:2千地質(zhì)填圖工作,選擇成礦有利部位進(jìn)行槽探鉆探驗(yàn)證,以大致了解礦體空間分布規(guī)律,提出下一步工作建議。
[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.
