乌干达优势矿产成矿地质特征及远景区划分
|
摘要
作者在野外考察和资料整理分析的基础上,根据乌干达区域地质构造发展演化、矿产资源类型、矿点(矿化点)分布以及典型矿床特征,圈定了4个金有利成矿远景区:Busia金矿区,Mubende金矿区,Buhweju-Mashonga金矿区和Karamoja金矿区。通过对乌干达优势矿产资源的整体评估,划分了6个具有良好成矿潜力的多金属成矿远景区:基伦贝(Kilembe)铜-钴成矿区,布惠朱(Buhweju)金成矿区,穆本德-班尤诺(Mubende-Bunyoro)金、钨、锡等多金属成矿区,基索罗-恩通加莫(KisoroNtungamo)金、锡、绿柱石等多金属成矿区,布希亚(Busia)金成矿区,卡亚穆伽(Karamoja)金、铜等多金属成矿区,并对各成矿远景区进行了简要阐述。
Based on field investigation and data analysis, According to the types of mineral resources and characteristics, distribution of mineral occurrence(mineralization points), characteristics of typical deposits and development and tectonic evolution in Uganda four favorable area for forming gold deposits are delineated: Busia metallogenic area, Mubende metallogenic area, Buhweju-Mashonga and Karamoja metallogenic area. Based on the overall assessment of Uganda's dominant mineral resources, six have good metallogenic potential favorable area for forming polymetallic metallogenic prospective are divided: Kilembe copper-cobalt metallogenic area; Buhweju gold metallogenic area; Mubende-Bunyoro gold, tungsten, tin, etc polymetallic metallogenic area; Kisoro-Ntungamo gold, tin, beryl, etc metallogenic area; Busia gold metallogenic area;Karamoja gold, copper, etc polymetallic metallogenic area. All of these metallogenic area are briefly described.
