摘　　要：文章通过对喀麦隆东部省Nkamouna钴镍矿床的成矿地质条件、矿床地质特征、矿石类型及矿床成因的初步分析与研究,认为矿床是由超基性岩蛇纹岩在热带及亚热带常年高温、雨旱交替且年降雨量较大的地区经风化、淋滤、沉积富集而成矿,与在中生代、新近纪第四纪的热带、亚热带气候条件下形成的蛇纹岩风化壳有关。Based on the preliminary analysis and study of the ore-forming geological conditions,geological characteristics,ore types and genesis of the nkamouna cobalt nickel deposit in Eastern Cameroon,it is believed that the deposit is formed by the weathering,leaching and sedimentary enrichment of ultrabasic serpentinite in the tropical and subtropical regions with high temperature,alternate rain and drought and high annual rainfall,and in the Mesozoic and Neogene It is related to the weathering crust of serpentine formed in the tropical and subtropical climate of Quaternary.
