贵州纳雍地区牛蹄塘组钼镍多金属矿床地质特征及找矿前景
|
摘要
黔西北纳雍县木城—水东钼镍矿床是近年来在黔西地区取得的重要找矿成果,在矿产资源调查评价过程中,共圈定出14个钼、镍矿体,矿体均位于下寒武统牛蹄塘组(1n)页岩中,呈层状、似层状及透镜状产出。钼镍矿体平均厚度为0.8 m,Mo平均品位0.35%,Ni0.32%。估算钼金属资源(332+333)总量8.4万t,共伴生有益组分镍金属资源总量7.6万t,Mo、Ni均达到中型矿床规模。本文介绍了区内镍钼矿床的矿床地质特征、矿体形态、矿物组合等,初步探讨了矿床成因。通过在该区多年勘察工作的经验总结,结合区内地球化学异常特征对该区的MoNi找矿前景进行了分析。根据现有下寒武统牛蹄塘组Mo-Ni多金属矿床中普遍有超常富集贵金属富集规律,下一步工作建议加强对木城-水东Mo-Ni矿床中贵金属元素评价。
Mucheng-Shuidong Mo-Ni deposit is an important prospecting fruit in Guizhou province. 14 Mo-Ni ore bodies have been delineated in the process of mineral resources investigation and evaluation. The ore bodies are layered or lenticular in Niutitang group of lower Cambrian. The average thickness of the ore body is 0. 8 m,average grade of Mo is 0. 35%,and average grade of Ni is 0. 32%. It is estimated that the total amount of molybdenum resources(332 + 333) is 84 thousand tons,and the total useful metal nickel resources are 76 thousand tons,and this Mo-Ni deposit reach the middle scale. This paper introduces and discusses the deposit 's geology feature,ore bodies,mineral assemblages and genesis of Mo-Ni deposit in research area. Based on the experience of many years' prospecting work in the area,combined with geochemical anomalies in the area,the Mo-Ni prospecting potential in this area is analyzed. According to the existing rule of supernormal enrichment of precious metals in the Mo-Ni polymetallic deposit in the Niutitang group of lower Cambrain,the next step is to promote the evaluation of the precious metal elements in the Mo-Ni deposit in Mucheng-Shuidong area.
