摘　　要：通过对井冈山浆山钨锡多金属矿区进行1/1万土壤地球化学扫面工作,对Cu、Pb、Zn、W、Sn、Mo等元素的含量特征参数、元素间相关关系等特征统计并绘制异常图,研究了矿区土壤地球化学特征及异常特征。研究结果表明:浆山矿区W、Sn等高温成矿元素的异常强度较高,规模大,连续性好,成矿元素组合异常发育在浅成、超浅成、浅剥蚀的小侵入体(白竹园岩枝)及其内外接触带上,成矿物质主要来自燕山期岩浆早期分异的气水溶液成矿物质,成矿作用(内生)与燕山期侵入岩活动相关,指明了今后找矿方向。Through the 1/1 myriad soil geochemistry jiangshan Jinggangshan mountain tungsten-tin polymetallic mining area scanning,Cu,Pb,Zn,W,Sn,Mo and other elements of the content feature parameters,the relations between elements of statistics and drawing anomaly map,study and abnormal geochemical characteristics of soil in mine characteristic.Results:jiangshan W,Sn and other high metallogenic element anomalies with high strength,large scale,good continuity,ore-forming elements combination of abnormalities in small intrusions hypabyssal,super shallow,shallow denudation(white bamboo garden Rock Branch)and the inner and outer contact zone,metallogenic material mainly from Yanshan magmatic early differentiation of the gas into the aqueous solution of minerals,mineralization(endogenous)rock activity associated with Yanshan intrusive,pointed out the prospecting direction for the future.
