【摘要】 惹一卡位于松潘—甘孜造山带东南缘,雅江—马尔康大型锂矿带上,地质情况复杂,成矿条件优越。通过对该区开展1∶1万上壤地球化学测量,分析元素地球化学特征、单元素异常特征、异常赋存的地质环境等,共圈定了5个异常。经异常查证发现R5、R6两条含锂铷伟晶岩脉,经地表取样初步估算3341资源量达到中型矿床规模,取得了较好的找矿效果,表明该地区具有巨大的找矿潜力。结合成矿地质条件与元素异常分析,R5、R6南北两侧有多个浓度中心,深部情况不明,进一步对R5、R6开展深部工作,有望实现找矿突破性进展。更多还原

【Abstract】 Reyika is located on the southeastern margin of the Songpan-Ganzi orogenic belt and on the Yajiang-Maerkang large-scale lithium belt. The geological conditions are complex and the metallogenic conditions are superior. Through the geochemical measurement of 1 ∶ 10000 Shangdong in the area,and analyzing the geochemical characteristics of elements,the anomalous characteristics of single elements,and the geological environment of anomalies,five anomalies were identified. After anomaly verification,it was found that both R5 and R6 contained lithium and strontium pegmatite veins,and the overall reserves reached medium-sized,which achieved good prospecting effect,indicating that the area has great prospecting potential. Combined with the analysis of ore-forming geological conditions and elemental anomalies,R5 and R6 have multiple concentration centers on both sides of the north and south. The deep situation is unknown. Deep work on R5 and R6 is expected to achieve breakthrough prospecting.更多还原
