摘要
梨木岭矿床位于武当—桐柏—大别成矿带东段,是东大别南麓成型的钼多金属矿产地之一。矿区及其外围已开展地质测量、水系沉积物测量、土壤测量、岩石剖面测量、激电测量、音频大地电磁测深、航磁测量、放射性测量、遥感解译以及多光谱遥感蚀变信息提取等工作,先后发现脉型钼矿主矿体和石英脉型、层控矽卡岩型钨矿等伴生矿体,其中脉型钼矿与石英脉型钨矿主要赋存于NNE向断裂破碎带中,层控矽卡岩型钨矿则赋存于大别岩群大理岩与片麻岩类、变粒岩类的岩性界面上。在系统分析前人工作成果的基础上,结合较为齐全的地、物、化、遥综合找矿信息,总结梨木岭钼多金属矿床的找矿标志,并圈定有利找矿靶区。结果表明,受NNE向断裂控制的脉型钼矿和石英脉型钨矿具有较为明显的W-Mo-Cu-Bi-Ag组合异常、低磁—高阻—高极化率异常以及黄铁矿—绢云母—绿泥石化蚀变高光谱异常等找矿标志;层控矽卡岩型钨矿则具有较为明显的W-Sn-Zn组合异常和黑云母—绿泥石化蚀变高光谱异常。利用不同矿化类型的综合信息找矿标志,运用相似类比、求异等矿产资源评价和预测的基本理论,在梨木岭矿区及其外围圈定了6处找矿靶区,为矿区以及外围矿产勘查提供了依据和方向。
The Limuling deposit as a molybdenum polymetallic ore deposits formed in the southern foothills of the East Dabie,is located in the eastern section of the Wudang Tongbai Dabie metallogenic belt.The Geological surveys,stream sediment surveys,soil surveys,rock profile surveys,induced polarization surveys,audio magnetotelluric sounding,aeromagnetic tellurics,radiometric surveys,remote sensing interpretation,and multispectral remote sensing alteration information extraction have been carried out in the mining area and its surrounding areas.The main ore body of vein type molybdenum deposits,as well as associated ore bodies such as quartz vein type and layer controlled skarn type scheelite deposits,have been discovered successively.Vein type molybdenum ore and quartz vein type tungsten ore mainly occur in the NNE trending fault fracture zone,while layer controlled skarn type tungsten ore bodies occur in the lithological interface between the Dabie rock group marble and gneiss or granulite.Based on the systematic analysis and research of previous work results,combined with comprehensive geological,physical,chemical,and remote exploration information,the prospecting indicators of the Limuling molybdenum polymetallic deposit were summarized.It is believed that vein type molybdenum deposits and quartz vein type scheelite deposits controlled by NNE faults have obvious prospecting indicators such as W-Mo-Cu-Bi-Ag element combination anomalies,low magnetic high resistance high polarizability anomalies,and pyrite sericite chlorite alteration hyperspectral anomalies;Layered skarn type scheelite exhibits more obvious W-Sn-Zn element combination anomalies and biotite chlorite alteration hyperspectral anomalies.This article uses comprehensive information of different mineralization types to identify mineral indicators,and applies basic theories of mineral resource evaluation and prediction such as similarity analogy and differentiation.Six prospecting target areas are delineated in the Limuling mining area and its periphery.The research results provide a basis and direction for mineral exploration in the mining area and its periphery.
