广东省阳山县石寨铅锌多金属矿地质特征冼源宏;郭华;占达积;王灿松【摘要】阳山县石寨矿区隶属南岭钨锡多金属成矿带,属矽卡岩型铅锌多金属矿,是武警黄金九支队首次针对此类型矿床进行勘查。
矿区内花岗岩体广泛与石炭系地层接触,接触带长度延伸较长,具有较好的成矿条件。
已发现的矽卡岩带,受接触带构造影响,在走向与倾向上整体呈“S”型舒缓波状,铅锌矿体主要赋存于矽卡岩带中。
通过物化探基础性工作,并利用钻探及槽探工程进行查证,物化探异常与已发现矿脉吻合度较高,且深部呈现铅锌多金属元素富集增高的趋势,显示了较好的找矿前景。
通过对区内多金属矿床地质特征、成矿规律分析与找矿前景分析总结,为在该区深部进一步开展找矿勘探,扩大其远景规模提供了明确方向和详实的地质资料。
%Shizhai mining area of Yangshan is a skarn-type Pb-Zn polymetallic deposit which is located in Nan-ling W-Sn polymetallic metallogenic belt.It’s the first time that No.9 Gold Geological Team of CAPF has conducted exploration works on this type of deposits.The metallogenic conditions are favorable because the contact between granite body and Carboniferous stratum is extensive and long in length in this mining area. Under the influence of the structure of contact zone,the discovered skarn belt shows S-shaped gentle wave-forms in strike and trend.The Pb-Zn orebodies mainly occur in the skarn belt.Through geophysical and geo-chemical exploration as well as drilling and trenching works ,it is verified that the geophysical and geoche-mical anomalies match very well with the discovered ore veins,and elements like Pb and Zn are enriched and increased in the deeper part.It is indicated that themining area has great prospecting potential.This paper analyzed and summarized the geological characteristics,metallogenic regularity and prospecting potential of the poly-metallic deposits in the area,and provided a clear direction and full and accurate geological data for further exploration works in the deep part of this area and expansion of prospecting potential area in the future.【期刊名称】《矿产与地质》【年(卷),期】2016(030)001【总页数】6页(P29-34)【关键词】铅锌多金属矿;地质特征;成矿规律;找矿前景【作者】冼源宏;郭华;占达积;王灿松【作者单位】中国人民武装警察部队黄金第九支队,海南海口 571127;中国人民武装警察部队黄金三总队,四川成都 610000;中国人民武装警察部队黄金第九支队,海南海口 571127;中国人民武装警察部队黄金第九支队,海南海口 571127【正文语种】中文【中图分类】P618.4石寨矿区隶属南岭钨锡多金属成矿带,位于郴州―怀集断裂带与阳山―乳源断裂组交汇部位,大地构造位置处于华夏板块粤北坳陷内,连阳岩体东北角(图1)。

1 引言南岭地区是全球最重要的钨锡矿床集中分布区,早期探明的西华山钨矿、柿竹园钨铋钼锡矿床、黄沙萍铅锌多金属矿、宝山铜多金属矿、盘古山钨铋矿、大吉山钨、铌钽矿等大型矿床,在20 世纪末又有一系列重大发现,如探明的芙蓉超大型锡矿、淘洗坑钨锡矿、铜坑嶂钼矿、八仙脑钨锡多金属矿、荷花萍锡矿、园岭寨钼矿、银坑桥子坑金银矿等矿床,预示该区域内进一步找矿潜力的巨大。
南岭成矿带的第二找矿空间何在?许建祥等[1]提出了“五层楼+地下室”的找矿模型,杨明桂等[2]提出了“多位一体”的成矿模式,以同位素年代学为依据,从横向上和纵向上等2 个方面,分析了南岭成矿带中、东段的第二找矿空间,为进一步开展地质找矿工作提供了理论依据。
2 南岭中、东段的矿床基本特征及其成矿年代学研究概况本文的南岭成矿带的中、东段地区包括湘南、赣南和粤北地区,是钨、锡矿床的集中分布区,主要矿化类型包括矽卡岩型(矽卡岩+云英岩复合型)、石英脉型(石英+云英岩复合型)、斑岩型等,最近又发现了石英脉+破碎带复合型。
钨锡矿化明显受成矿花岗岩和围岩的岩性控制,其中中生代的成矿花岗岩以富含钨锡组分为特征,并具有多阶段分异演化、多阶段侵位和多阶段成矿的特征[3-5]。
地层组分决定了矿床类型,当赋矿围岩为碳酸盐岩或富含钙质砂岩时,则形成矽卡岩型矿床;当赋矿围岩为长英质砂岩时,则形成外带型石英脉型[3];当赋矿围岩为泥质板岩或花岗岩时,则形成内带型石英脉型或石英脉+云英岩复合型。

南岭湘南吴家坪锡矿成岩成矿时代研究夏杰;卢友月;付建明;张遵遵;程顺波;李剑锋;宁勇云;冯经平;张吉梼【期刊名称】《地质通报》【年(卷),期】2024(43)4【摘要】南岭吴家坪锡矿为湖南大义山地区近年新发现的具有中型以上远景规模的云英岩型矿床,矿体呈脉状产于大义山复式花岗岩体内部,受NE向断裂控制。
为确定其成岩、成矿时代,总结大义山地区成矿规律,指导区域找矿及勘查工作,对赋矿围岩中粗粒斑状黑云母二长花岗岩(PM21-19)、中细粒斑状黑云母二长花岗岩(PM21-27)进行了LA−ICP−MS锆石U−Pb定年研究。
测年结果表明,其成岩年龄为157.1±1.1 Ma(MSWD=0.55)和153.7±1.2 Ma(MSWD=0.55),属燕山早期。
同时,获得云英岩型锡矿石中石英Rb−Sr等时线年龄为148.1±2.1Ma(MSWD=0.52)。
结合区域资料认为,吴家坪锡矿成岩成矿时代为燕山早期,属南岭地区中生代成岩成矿高峰期(160~150 Ma)的产物。
