根据罗布莎铬铁矿工业矿体主要产于蛇绿岩壳一幔边界(即岩石莫霍面)以下的一定层位、一定岩相构造带内及其显示的矿带分布规律.认为当前找矿的首要目标在于牢牢把握矿带这个大方向.鉴于以往找矿勘探主要限于地表和浅部"就矿找矿"的找矿方法.进一步加大矿带中深部中下矿段隐伏矿体的找矿力度乃是当务之急.对各区段提出了不同的找矿任务和靶区选择的意见.并预测该区(包括罗布莎、香卡山和康金拉3个矿区)铬铁矿远景规模有望大大提升现有储量规模的等级.

Economic ore bodies of chromite in the Luobusha area,Tibet are mainly hosted in a specific lithological horizon beneath the boundary of ophiolitic crust and mantle that is beneath the Moho boundary)and related to specific lithological structures.They occur mainly as ore-bearing belts.Currently,it's quite important to stick to this principle of the ore-bearing belts as general direction.perative to strengthen exploration extent in discovering hidden orebodies in the middle and bottom parts of the ore belt.The authors also Droposed various exploration methods to different ore sectiom and some suggestions on how to delineate potcntiM areas.In the end,the paper predicted that the prospective scale of chromite in Lubusha,Xiangkashan and Kangquanla mineralization areas has a big potential to upgrade several times of the proven reservoirs.
