藏南冈底斯带西段铁矿找矿工作新进展

Major progress in iron ore finding in the western segment of the Gangdise belt, southern Tibet, China

摘要: 通过1：25万区域地质调查,在冈底斯带西段革吉县南部地区新发现了具有进一步工作价值的铁矿及含铜铁矿点4处、银铜多金属矿点2处.重点对桑穷勒磁铁矿、含铜磁铁矿及列马镜铁矿进行了初步评价.其中前者磁铁矿矿石资源量为401.59Mt,后者镜铁矿矿石资源量18.50Mt.这是冈底斯带西段铁矿等找矿工作的重要新进展.

Abstract: During the 1:250000 regional geological survey, four iron copper-bearing iron occurrences and two silver-copper polymetallic occurrences which merit further work were found in southern Ge'gyai County, in the western segment of the Gangdise belt, Tibet. In the paper the authors focus on a preliminary evaluation of magnetite and cupreous magnetite at Sangqiongle and specularite at Liema. This ore prospect evaluation shows that there are 401.59 Mt of magnetite ore resources at Sangqiongle and 18.50 Mt of specularite ore resources at Liema.
