| 中文摘要: |
| 江西夏家铺地区位于江西省北部,为典型的南方湿润半湿润中低山景观区。江西省地质调查研究院于 2013—2015年主要采用化探方法在该地区开展了矿产远景调查工作, 圈出了多个地球化学异常。主要发育3种元素组合的综合异常,可分为以Sn为主成矿元素的Sn、Pb、Zn、Cu、As 、Sb、F、W、Mo、Bi组合、以F为主要成矿元素的F、Pb、Zn、As、Bi组合,以Sb、Au、As元素的为主的Au、Ag、As、Mo、Bi组合,前二者为受地层＋构造＋隐伏花岗质岩体控制的类异常,后者为可为受地层＋构造＋煌绿岩、辉绿玢岩脉(墙)共同控制的异常,反映出不同的成矿作用、矿化空间、分布规律。 |
| 英文摘要: |
| The Xiajiapu area in Jiangxi Province is located in the north of Jiangxi Province. It is a typical southern humid to sub-humid low-middle mountain landscape area[1]. From 2013 to 2015, Geological Survey of Jiangxi Province mainly used geochemical exploration methods to conduct mineral prospective investigations in the region, and circled out a number of geochemical anomalies. There are three comprehensive anomalies with their main element assemblages:Sn, Pb, Zn, Cu, As, Sb, F, W, Mo, Bi assemblages; F, Pb, Zn, As, Bi assemblages; Au, Ag, As, Mo, Bi assemblages with Sb, Au, As as the dominant elements. The first two anomalies are controlled by stratigraphic + tectonic + concealed granitic rocks, while the third anomaly could be controlled by strata + tectonics + lamprophyrite, diabase-porphyrite veins (dykes). Those anomalies reflect different metallogenesis, spatial mineralization and distribution pattern. |
