中文摘要:
      矿区地处于基巴拉褶皱带刚果(金)马诺诺东部,成矿地质条件优越。通过系统地质工作,发现该区矿床为LCT(锂-铯-钽)花岗伟晶岩型矿床,区内共圈定矿体2条,分别为Ⅰ-1和Ⅱ-1,铌钽金属资源量约1万t,锡金属资源量约20万t。矿体均呈层状、似层状,严格受伟晶岩控制产出。矿石类型主要为风化矿石和原生矿石,矿石矿物主要为铌钽铁矿、铌钽锰矿等。该区矿体规模大,矿物以铌钽矿为主,同时伴生少量锂、锡和铍,经济价值高。通过后期进一步的勘查工作,资源量将会进一步扩大。
英文摘要:
      The mining area is located in the east of manono in the kibalan fold belt of the Congo(Kinshasa).There are 2 ore bodies to be found in the ore area ,including Ⅰ-1 and Ⅱ-1,which mining area belongs to the LCT (lithium-cesium-tantalum) granite pegmatite type deposit,by the systematic geological work.The ore bodies are stratiform and stratiform-like and are strictly controlled by pegmatites. The ore types are mainly weathered ore and primary ore, and the ore minerals are mainly niobium tantalite and niobium tantalum manganese ore.The ore body in this area is large and the mineral is mainly niobium tantalum, accompanied by a small amount of lithium, tin and beryllium,which has a high economic value.There is a considerable prospect of this ore aera, and the amount of resources will be further expanded by later exploration
