【摘要】：河南省崤山东部位于华北地台南缘,卢氏—洛宁断陷北部。地层区划属华北区豫西分区,涉及熊耳山小区和渑池—确山小区。研究区位于熊耳山地区东部,成矿地质条件优越。论文在深入分析崤山地区成矿地质背景的基础上,重点对研究区的地质构造特征、岩浆活动情况、地球物理、地球化学以及遥感影像异常特征进行了研究。在此基础上,采用地质、物探、化探及遥感综合信息法确定了有利找矿靶区。论文取得的主要成果如下:1、在总结研究区成矿地质条件的基础上,通过对区内大石凹闪长岩体和中河花岗斑岩体开展调查研究,认为中河花岗斑岩体与区内Pb、Zn矿成矿关系密切。2、在对研究区典型矿床综合分析的基础上,总结了该区多金属矿床成矿规律,并初步探讨了区域矿床成因模型。3、通过1:5万高精度磁法测量及数据处理,在研究区圈定了9个弱磁异。1:5万水系沉积物测量在研究区圈定了单元素异常19个,组合异常8个,综合异常6个。根据遥感解译的线、带、环、色、块及典型蚀变矿物绿泥石、褐铁矿、重晶石、方解石等矿物信息,在本研究区共划分了4个找矿有利异常区。4、根据区内地质、物探、化探及遥感信息,提出了研究区主要找矿标志,并初步建立了找矿模型。在此基础上运用综合信息量法圈定了7个找矿靶区,其中A级1个,B级2个,C级4个。
[Abstract]:Xiaoshan part of Henan Province is located on the southern margin of North China platform and north of Lushi-Luoning fault depression. The stratigraphic regionalization belongs to the western Henan subdivision of North China region, involving Xiong Ershan area and Mianchi Keshan district. The research area is located in the east of Xiong Ershan area. On the basis of deep analysis of the metallogenic geological background in Xiaoshan area, the paper focuses on the geological structural characteristics, magmatic activity, geophysics, and the characteristics of the geological structure, magma activity and geophysics in the study area. Geochemical and remote sensing image anomalies are studied. On this basis, geological, geophysical exploration, The favorable ore-prospecting target area was determined by geochemical exploration and remote sensing comprehensive information method. The main results obtained in this paper are as follows: 1. On the basis of summarizing the metallogenic geological conditions of the study area, the Dashiconda diorite and Zhonghe graniorite are investigated and studied. It is considered that the Zhonghe granitic porphyry body is closely related to the PbPb-Zn ore mineralization in this area. Based on the comprehensive analysis of the typical deposits in the study area, the metallogenic regularity of the polymetallic deposits in this area is summarized. In this paper, the genetic model of regional ore deposit .3is discussed preliminarily. By measuring and data processing with high precision magnetic method of 1: 50 000, 9 weak magnetic anomalies. 1: 50 000 water system sediment survey in the study area have delineated 19 single element anomalies and 8 assemblage anomalies in the study area. According to the information of line, belt, ring, color, block and typical altered mineral chlorite, limonite, barite and calcite, four ore prospecting favorable anomaly areas. Based on geophysical, geochemical and remote sensing information, the main prospecting markers in the study area are put forward, and the prospecting model is preliminarily established. On the basis of this, seven prospecting target areas are delineated by the method of comprehensive information quantity, of which one is A class B and 2 are C class.
