| 摘 要： | 超铁镁岩(超基性岩)在热带、亚热带地区,通过红土化作用,可形成具有重要工业意义的风化壳硅酸镍矿床。其主要工业矿物为暗镍蛇纹石、镍绿泥石、绿高岭石和蜡蛇纹石等。矿床的垂直分带明显,由上而下主要为褐铁矿(赭石)带,中间绿高岭石带或硅质带,淋滤蛇纹岩带或腐蚀岩带,以及原岩带或蛇纹石化橄榄岩带。

| Abstract: | The weathering crust silicate nickel ore deposit which has important industrialsignificance could be formed by lateritization in tropical and subtropical region.Their chief industrial minerals are garnierite. nepouite, nontronite, kerolite,etc. The secondary vertical zoning is obvious. and is chiefly of limonite (redocher) zone, intermediate nontronite zone or siliceous zone, leached serpentitezone or alteration rock zone, and original rock zone or serpentinized peridotitezone. |

| Keywords: | weathering crust nickel oxide nickel silicate ore formation ultramafic rocks tropical and subtropical zones lateritization vertical zoning of ores |
