贵州贞丰水银洞金矿矿床成因与成矿模式：来自载金黄铁矿NanoSIMS多元素Mapping及原位微区硫同位素的证据
水银洞金矿 环带黄铁矿 元素Mapping 原位硫同位素 岩浆活动
2018/12/5
贵州贞丰水银洞金矿是中国“滇黔桂”金三角地区最具代表性的超大型卡林型金矿床之一。黄铁矿和毒砂是水银洞金矿的主要载金矿物。背散射电子图像和NanoSIMS高分辨率元素面扫描分析显示载金黄铁矿普遍发育环带结构，不同环带的微量元素种类和含量有显著差别。如增生环带富集Au、Cu、As元素，而核部则相对贫这些元素，富Se。同时，即使在富Au环带中，Au和微量元素也并非均匀分布，环带之中又发育次一级环带。这表...

Geological mapping in Latvia:from useful minerals and structures to georesources
Geological mapping useful minerals georesources
2009/10/21
Traditional geological mapping in Latvia was initiated in the 1930s. Basic geological mapping, however, started just after the Second World War and thus provides a very simplified picture about geolog...
