【摘要】:近期相當長的時間內(nèi),各地固體礦產(chǎn)勘查項目中,有一定找礦突破者較少。其主要原因在于各種資料未進行深入的地物化特征的相互關系研究,資料數(shù)據(jù)特征相互關系研究較為不足。作者認為,在礦產(chǎn)勘查工作中,尤其針對隱伏礦體,各種勘查方法優(yōu)化合理利用,對各種致礦信息特征的相互關系進行疊合、印證的綜合研究顯得尤為重要。本文基于《內(nèi)蒙古自治區(qū)化德縣田寶溝鎢銅多金屬礦勘查》項目的整體勘查過程,對不同勘查方法進行了合理優(yōu)化利用并投入實施,取得了可喜的地質找礦成果。在綜合研究了勘查區(qū)的成礦特征的基礎上,進行了合理的找礦預測分析,對下一步勘查工作提供了重要指導意義。通過田寶溝鎢銅礦區(qū)野外和室內(nèi)各項研究工作,在圈定的7處1:10000綜合土壤化探異常中,AP-5號化探綜合異常內(nèi),發(fā)現(xiàn)兩條與條帶狀相對高極化低阻異常相對應的黑鎢礦化石英脈帶。同時深部鉆探工程也有揭露。分析得出,AP-5號化探綜合異常深部具有鎢礦體品位變富、厚度變厚的趨勢;AP-2、AP-6等兩處具有重要成礦潛力;認真、扎實做好前期地質、化探、物探等掃面工作,是提供找礦線索最為重要的基礎工作;著重研究具有條帶狀、串珠狀或橢圓狀等形態(tài)具一定規(guī)律性的綜合異常(包括地質礦化異常)特征,是供化探、電法、磁法以及槽探、鉆探等勘查方法適時優(yōu)化應用的重要依據(jù);化探異常、極化率異常走向及其幾何形態(tài)結合礦化脈進行分析,是縮小找礦范圍的重要思路和方法;礦體受巖體熱液上涌產(chǎn)生的內(nèi)部構造裂隙系統(tǒng)控制,構造裂隙為礦體的賦存提供了良好的儲礦空間;研究區(qū)黑鎢礦成礦模式為巖漿熱液上涌產(chǎn)生放射狀構造裂隙系統(tǒng)模式,為充填交代(石英脈)型鎢礦床,呈鎢礦“五層樓”模式。
[Abstract]:For a long time in the near future, there are few solid mineral exploration projects.The main reason lies in the lack of in-depth research on the relationship between geophysical and chemical characteristics of various data, and the lack of research on the interrelation of data features.The author believes that in mineral exploration, especially for concealed orebodies, the optimization and rational utilization of various exploration methods and the superposition of the interrelation of various ore-causing information characteristics are particularly important.Based on the whole exploration process of Tianbaogou tungsten and copper polymetallic ore exploration project in Huade County, Inner Mongolia Autonomous region, this paper optimizes the utilization of different exploration methods and puts them into practice, and obtains gratifying geological prospecting results.Based on the comprehensive study of the metallogenic characteristics of the exploration area, a reasonable ore prospecting prediction analysis is carried out, which provides important guidance for the next exploration work.Through field and laboratory research in Tianbaogou tungsten-copper mine area, two wolframite fossil veins corresponding to banded relatively high polarization and low resistivity anomalies were found in 7 delineated integrated geochemical anomalies of 1: 10000 integrated soil.At the same time, deep drilling projects have also been exposed.It is concluded that in the depth of the comprehensive anomaly of QianAP-5 geochemical exploration, the tungsten ore body has become rich in grade and the thickness is thicker and the two places, such as AP-2 and AP-6, have important metallogenic potential, and have done well the work of sweeping surface of Prophase geology, geochemical exploration and geophysical prospecting, etc, in earnest and in a down-to-earth manner.It is the most important basic work to provide the clues for prospecting, especially to study the comprehensive anomaly (including geological mineralization anomaly) with certain regularity in the shape of strip, bead or ellipsoid, which is used for geochemical exploration, electrical method, magnetic method and trough exploration.The important basis for optimizing the application of exploration methods such as drilling, geochemical exploration anomalies, polarization anomalies and their geometric patterns combined with mineralized veins are important ideas and methods to narrow down the scope of prospecting.The orebody is controlled by the internal structural fissure system of hydrothermal upwelling of rock mass, which provides a good storage space for the occurrence of orebody, and the wolframite metallogenic model in the study area is the radial structural fissure system model of magmatic hydrothermal upwelling.In order to fill the metasomatic (quartz vein) type tungsten deposit, the five-story model of tungsten deposit is presented.
