青海东昆仑五龙沟地区化探次生晕觅金效果探讨
|
摘要
青海东昆仑地区1∶50万化探次生晕扫面工作中,根据少量的采样点分析成果,快速掌握了该区Au及其他元素的矿化信息。通过进一步的化探次生晕逐级加密分解,在五龙沟地区圈定了1∶2.5万化探次生晕找矿靶区26处,证实了化探次生晕勘查技术方法是快速、有效、准确锁定最小勘查区范围的技术方法。对26处靶区大比例尺(1∶2 000)原生晕剖面定位,槽探工程控制揭露,坑、钻探工程走向和倾向追索控制,最终在五龙沟地区发现大型金矿床3处,中型金矿床3处,小型金矿床6处,累计金金属量近120t。进一步证实了化探次生晕勘查技术方法的有效性和觅金效果的显著性。
Through carrying out the 1∶500 000 secondary halo geochemical exploration in East Kunlun,Qinghai Province,the information on the mineralization of gold and other elements in the area has been acquired rapidly after analyzed a small number of geochemical sampling.And 26 prospecting targets had been delineated by carrying out the 1∶25000 secondary halo geochemical exploration in Wulonggou area.It is proved that the secondary halo geochemical exploration is a fast,effective and accurate method to determine the minimum exploration area.By positioning large-scale(1∶2 000)original halo profile,groove engineering and pit-drilling engineering,3 large-scale,3 medium-sized and 6 small-scale gold deposits have been identified in Wulonggou area,which is controlled by the strike and dip.The obtained amount of gold metal is nearly 120 tons.It is also proved that the exploration technique of secondary halo geochemical exploration is effective and significant in gold prospecting.
