【摘要】：近期相當(dāng)長的時(shí)間內(nèi),各地固體礦產(chǎn)勘查項(xiàng)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(jìn)行深入的地物化特征的相互關(guān)系研究,資料數(shù)據(jù)特征相互關(guān)系研究較為不足。作者認(rèn)為,在礦產(chǎn)勘查工作中,尤其針對(duì)隱伏礦體,各種勘查方法優(yōu)化合理利用,對(duì)各種致礦信息特征的相互關(guān)系進(jìn)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(xiàng)目的整體勘查過程,對(duì)不同勘查方法進(jìn)行了合理優(yōu)化利用并投入實(shí)施,取得了可喜的地質(zhì)找礦成果。在綜合研究了勘查區(qū)的成礦特征的基礎(chǔ)上,進(jìn)行了合理的找礦預(yù)測分析,對(duì)下一步勘查工作提供了重要指導(dǎo)意義。通過田寶溝鎢銅礦區(qū)野外和室內(nèi)各項(xiàng)研究工作,在圈定的7處1:10000綜合土壤化探異常中,AP-5號(hào)化探綜合異常內(nèi),發(fā)現(xiàn)兩條與條帶狀相對(duì)高極化低阻異常相對(duì)應(yīng)的黑鎢礦化石英脈帶。同時(shí)深部鉆探工程也有揭露。分析得出,AP-5號(hào)化探綜合異常深部具有鎢礦體品位變富、厚度變厚的趨勢(shì);AP-2、AP-6等兩處具有重要成礦潛力;認(rèn)真、扎實(shí)做好前期地質(zhì)、化探、物探等掃面工作,是提供找礦線索最為重要的基礎(chǔ)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(zhì)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(shí)優(yōu)化應(yīng)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(jié)合礦化脈進(jìn)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(gòu)造裂隙系統(tǒng)控制,構(gòu)造裂隙為礦體的賦存提供了良好的儲(chǔ)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(gòu)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.
