摘要:
腰站林场地区位于大兴安岭北部漠河盆地北端,成矿地质条件优越。为实现找矿突破,在1∶5万水系沉积物测量成果基础上,开展了1∶1万土壤地球化学测量。结果表明：腰站林场地区Au元素丰度高,变异系数大,为主成矿元素,As、Sb元素可作为指示元素,以中低温热液成矿作用为主,找寻金矿床潜力较大;综合异常元素多、规模大、强度高。在部分综合异常区地表槽探查证中发现2条矿化体,矿化特征与宝兴沟金矿床具有一定的类似性,认为该地区具有良好的找矿前景。

Abstract:
The Yaozhan Forest Farm area is located at the north end of the Mohe Basin in the north of the Greater Khingan Ranges,featuring favorable geological conditions for mineralization.To achieve prospecting breakthroughs,a 1∶10 000 soil geochemical survey has been carried out based on the results of a 1∶50 000 stream sediment survey.The results show that the Au element in the Yaozhan Forest Farm area has a high abundance value and a large coefficient of variation,and is the main ore-forming element,while As and Sb can be used as indicator elements.Besides,medium-low ore-forming hydrothermal fluids dominate the area,implying great potential to seek gold deposits.What’s more,there are many comprehensive anomalous elements in the soil with large scale and high intensity in the area.Two gold mineralized bodies have been found by trenching on the surface of part of comprehensive anomalous areas.The mineralization characteristics are similar to those of the Baoxinggou Gold Deposit.The study takes that it has promising prospecting prospects in this area.
