云南西畴县嘎机铅锌矿处于都龙复式花岗岩基向北侧伏的地带,铅锌矿体主要呈似层状赋存于构造破碎带中,该铅锌矿具有层控-岩浆期后热液矿床的特征。中寒武统田蓬组(∈2t)碳酸盐岩-碎屑岩互层组合、背斜构造、隐伏花岗岩体脊状凸出部位、矽卡岩化围岩蚀变和物、化探异常等是本区的主要找矿标志。  相似文献   

Fluorite deposits in China: Geological features,metallogenic regularity,and research progress     

《China Geology》2020,3(3):473-489

Fluorite is one of the important mineral raw materials in the industry. In China, it is mainly distributed in the provinces and regions such as Hunan, Zhejiang, Jiangxi, Inner Mongolia, Fujian, and Henan provinces, boasting huge reserves and large numbers of deposits. However, most of the fluorite deposits are on a small or medium scale. The main fluorite deposits in China were studied in this paper. Their geological features and metallogenic regularity were summarized and compared. Meanwhile, based on their main genetic factors including metallogenic fluid sources and main metallogenic geological processes, they were divided into two groups, namely meso-epithermal deposits and magmatic-hydrothermal deposits. Furthermore, based on the prospecting achievements and research progress obtained in fluorite deposits in recent years, prospecting potential predictions were made for the metallogenic prospect areas and major prospecting areas of fluorite in China. This aims to provide a theoretical basis and direction for future fluorite prospecting in China.  相似文献

安徽省濉溪县三铺地区秦楼铜金矿地质特征及找矿标志          下载免费PDF全文

王乐乐 《山东国土资源》2021,37(4)

秦楼铜金矿是三铺地区以金为主的矽卡岩型铜金矿床,位于安徽省濉溪县四铺乡秦楼村北部。矿区位于三铺岩体北接触带东端,岩体复杂,接触带及围岩层间裂隙为主要控矿构造。通过对秦楼铜金矿地质特征及矿床特征的认识,结合矿床物探异常特征,系统总结了三铺地区铜金多金属矿地质和物探找矿标志。研究表明:寒武纪中上统碳酸盐岩地层是三铺地区铜金多金属矿重要的赋矿层位;燕山期早白垩世的中酸性侵入体是寻找铜金多金属矿重要的标志;矿体赋存于局部磁异常的边部、局部磁异常梯级带上及布格重力异常梯级带上,为本区寻找铜金矿床指明了方向。  相似文献   

莫桑比克阿尔特里哥纳伟晶岩区概貌     

叶水泉  黄建平  夏明飞 《江苏地质》2006,30(1):10-12

莫桑比克阿尔特里哥纳是世界著名的伟晶岩区之一,蕴藏着丰富的稀有金属、稀土、水晶和宝石等矿产资源。伟晶岩脉及其矿体的分布受北北东—北东向和北西向断裂控制,北北东—北东向分布的伟晶岩矿床以稀有金属矿种为主,北西向分布的伟晶岩矿床以稀土金属矿种为主。伟晶岩体及其矿体呈脉状和透镜状等,规模大,富含钽铁矿、铌铁矿、锂云母、锂辉石、绿柱石、独居石、铌钇矿、烧绿石和泡铋矿等矿物。伟晶岩年龄410M a~560M a,是泛非构造运动的产物。按岩浆凝固浓度等分类,伟晶岩类型为稀有金属伟晶岩,部分为浅成、晶洞状伟晶岩;按化学成分等分类,伟晶岩以钠锂型为主,部分为钾型。伟晶岩体有明显的结构分带。  相似文献
