中文摘要:
      本文利用岩心、样品分析化验等资料对龙潭组的沉积环境、岩性组合、隐伏断裂构造以及含矿特征进行了研究,结果表明:研究区龙潭组为陆表海局限台地、潮控三角洲以及重力流沉积。区内存在两条隐伏断裂,走向为北西向,倾向北东的逆断层(F20)和走向为北东向,倾向北西的逆断层(Fx);龙潭组一段(P3l1)零星含矿段、龙潭组二段(P3l2)ⅢcⅢb含矿层、龙潭组三段(P3l3)的ⅣcⅣb含矿层具滑动擦痕、滑动镜面、碎裂化和角砾化特征,含矿层中的生物碎屑灰岩和粉砂质粘土岩、粘土质粉砂岩和钙质粘土岩,均有不同程度的见矿,是金富集的有利场所,为后期找矿预测方向提供了依据。
英文摘要:
      The study of sedimentary environment,lithologic combination,concealed fault structure and metallogenic characteristics of P3l Formation are conducted,which based on the analysis data of core and sample,etcThe results show that The P3l Formation is presented as the composition of restricted platform,tidal delta and gravity flow deep-water turbidite fan depositsThere are two hidden faults(reverse fault)in the area,which named F20 and Fx,including NW striking(inclines to NE)and NE striking(inclines to NW)In addition,The Interlaminar sliding emerged as the sporadically concealed faults among the P3l1 Formation,appeared between IIIc and IIIb in P3l2,between IVc and IVb in P3l3,the ore bearing stratum which featured of sliding scratches,sliding mirrors,fragmentation and brecciationBioclastic limestone,Silty mudstone,argillaceous siltstone and calcareous mudstone all have different degrees of ore finding among the stratum in the study areaIn other word,it was a favorable place for gold enrichment,which provides a basis for prospecting direction in the later period
