摘要
瓦勒尕矿区是青海省沟里地区整装勘查区之一,是沟里地区勘查成果最好的示范性矿区。通过研究区域地质、矿床地质特征和成矿分析,总结岩体成矿的规律及模式。与科研单位合作,结合瓦勒尕矿区实际勘查成果,发现勘查区内规模最大、品位最富的金矿体产于花岗岩体内部蚀变带中的Ⅵ号矿脉。结合成果总结出较为先进的找矿方法,为周边的找矿起到示范意义,在沟里地区实现了勘查理念的转变,从找老地层的石英脉型金矿转变为寻找构造蚀变岩型金矿。
Walega mining area is one of the Monoblock exploration area in Qinghai Gouli,is the best demonstration field ditch area exploration results.Through the study area deposit geological characteristics and metallogenic analysis,summarizes the metallogenic law of rock mass and mode,Through cooperation with scientific research units,combined with the actual exploration results,essential mining area,found exploration area,the richest mine,the largest scale and grade of ore bodies in granite rock mass in the internal alteration belt VI vein,According to the results Come to conclusion of advanced prospecting method,play a demonstration on the prospecting for the perimeter of the meaning,which changes the ditch area exploration idea,from looking for old strata quartz vein type gold deposits into looking for Structural rock type gold deposit.
