巴布亚新几内亚瑞木镍钴矿地质特征及成矿规律

Geological characteristics and mineralization regularity of Ramu Ni-Co deposit,Papua New Guinea

巴布亚新几内亚瑞木地区Marum基岩带上分布大面积的超基性岩体,红土化作用强烈。通过地质填图、钻探施工以及多种分析方法,对该区镍钴矿的地质特征和成矿规律进行了研究。研究结果表明,该区为典型的风化壳型红土镍钴矿床,具有规模大、埋藏浅、品位稳定等特点,经济价值巨大。

There is a large - area uhrabasic magmatic rock in the Marum bedrock belt in Papua New Guinea, and the lateriza- tion is very intense. The geological characteristic and mineralization regularity of nickel - cobalt ore were studied by geological map- ping, drilling, and various analytical methods. The results of study shows that this area is a typical weathering crust type laterite Ni - Co deposit with a large scale, shallow burying and stable grade, therefore, it has great economic value.
