中文摘要:
      本文通过对虎头崖区域地质背景、区域地球化学、成矿类型及成矿特征等方面的研究,对该区的找矿潜力进行了系统的分析,认为该区成矿时代主要集中于晚古生代—中生代,区域不同类型矿床在空间上分布具有叠加特点,矽卡岩型矿产与岩浆岩和地层接触关系表现密切,远程热液交代矽卡岩型矿床受岩浆热液、地层和构造的控制,矿体形成严格受地层控制,与地层产状及构造带平行分布。研究表明晚古生代—早中生代成矿系列是区域找矿主攻方向,主攻类型为矽卡岩—斑岩—热液型,应加强对中酸性岩体边部凹陷带、主断裂、次级断裂及斑岩体的研究和找矿。
英文摘要:
      Hutouya polymetallic ore area is located in the East Kunlun metallogenic belt. This paper mainly analyses and studies the regional geological characteristics of Hutouya area,which has important guiding significance for determining the metallogenic types and further prospecting work in this area. Based on the study of the regional geological background, regional geochemistry, metallogenic types and metallogenic characteristics of Hutouya area, the prospecting potential of the area is systematically analyzed.It is considered that the metallogenic epoch of the area is mainly concentrated in the Late Paleozoic-Mesozoic. The spatial distribution of different types of deposits in the area has superimposed characteristics. Skarn-type minerals are in contact with magmatic rocks and strata.The long-distance hydrothermal metasomatic skarn deposits are controlled by magmatic hydrothermal fluid, strata and structures, and the formation of ore bodies is strictly controlled by strata, which are parallel to the occurrence of strata and tectonic belts. The study shows that the Late Paleozoic-Early Mesozoic metallogenic series is the main direction of regional prospecting,and the main type is skarn-porphyry-hydrothermal type. The study and prospecting of sag zone, main fault, secondary fault and porphyry should be strengthened
