摘　　要：30~#矿权区位于菲律宾迪纳加特岛北部,区内发育有红土型镍矿床。本次勘查圈定4处矿(化)体,其中以Ⅰ、Ⅱ、Ⅲ矿(化)体的矿化范围较大,厚度变化系数为45%~50%(相对稳定),经济价值较高。红土型镍矿体平面上呈地毯状展布于地表,厚度受地形控制,富镍矿体分布于矿权区东部的5、6、11、12小区;剖面上从地表向深部矿体为铁质红土层、松散红土层及高岭土化蛇纹石化橄榄岩层。30~#矿权区红土镍矿矿床的形成经历了从普通矿到富矿两个阶段,红土镍矿石属于酸性矿石。The property No.30 is located in the north of Dinagat Island,Philippines where Lateritic Nickel Deposits are developed.In this prospecting are delineated 4 ore（mineralization）bodies of which the bodyⅠ,Ⅱ and Ⅲ are in large range with relative stable thickness（the variation coefficient 45%~50%）and high economic value.In plan the lateritic nickel ore body blankets the ground surface with thickness controlled by topography.Rich ore bodies are distributed at the sub-areas 5、6、11、12 in the eastern property.In section are ironic laterite,loose laterite and kaolintized and serptinized peridotite from surface to depth.The lateritic nickel deposit exposed to two stages i.e.the general ore and the rich or period and it belongs to acidic ore.
