广东莲花山断裂带南西段锡铜多金属整装勘查区锡矿成矿地质特征及找矿远景

本文通过系统分析广东莲花山整装勘查区最新锡矿勘查成果,总结了勘查区锡成矿地质特征、地球化学特征、成矿规律,认为锡成矿地质体为晚侏罗世~早白垩世中酸性侵入岩体、岩脉,锡矿产出的有利部位为北东~北东东向动力变质带、岩体与围岩接触带及锡地球化学异常带,综合各有利找矿信息,区内锡矿具有很大资源潜力,据此,圈定了5个锡矿找矿远景区,即:仙水沥-分水凹(仙水沥、矿隆坝、丹竹坑为代表)、塌山-江西坑(塌山、江西坑、尖吉山为代表)和长埔-吉水门(长埔、梅陇、吉水门、牛头山为代表)远景区,为今后本区矿产勘查提供依据。

Metallognetic Characteristics of Tin and Ore-Search Prospect In the Tin-Copper Polymetallic Ore-deposit in the Lianhuashan Fault Zone Integrated Exploration Area,Guangdong Province

This paper systematically analyzes the latest tin prospecting results in the integrated exploration area of The Lotus Hill,Guangdong Province,and summarizes the geological characteristics,geochemical characteristics,and metallogenic regularities of tin mineralization in the exploration area.The article considers that the tin metallogenic geological body is the Late Jurassic-Early Cretaceous intermediate-acid intrusive rock masses and dykes,the favorable parts of the tin outputs are the northeast to northeast eastward dynamic metamorphic belt,the contact zone between rock mass and adjoining rock,and the tin geochemical anomaly belt.The mining area has great resource potential according to the favorable prospecting information which was already acq.Hereby,five prospective areas for tin exploration are delineated.There are Xianshuili-Fenshuiao(represented by Xianshuili,Kuanglongba,Danzhukeng),Tashan-Jiangxikeng(represented by Tashan,Jiangxikeng,Jianjishan)and Changpu-Jishuimen(represented by Changpu,Meilong,Jishuimen,and Niutoushan)prospective areas,which will provide the basis for future mineral exploration in this area.
