| 摘 要： | 津巴布韦大岩墙北部红土型镍矿严格受橄榄岩控制,受地形地貌条件影响,位于橄榄岩出露的支谷山前缓坡地带的红土下部和靠山坡一侧.沟谷平坦和山上陡坡地段则无矿或有极薄氧化壳.该大岩墙上部橄榄岩、辉石岩、橄榄辉石岩带和铬铁矿层呈层状相互交替组成韵律性层序.在橄榄岩出露的地表植被稀疏,多为草本植物,而辉石岩、橄榄辉石岩带上呈现出茂密树丛.

| Abstract: | The lateritic nickel deposit in the northern Great Dyke of Zimbabwe is strictly controlled by the outcrop of peridotite and landform.The orebodies occur in the foreland valley and gentle slope.The peridotite,pyroxenite-peridotite belt and chromite layer form alternating rhythmic sequence on the top of the Great Dyke.The vegetation in the peridotite cropped area is mostly sparse herb plants; while that in the pyroxenite-peridotite belt is dense trees. |

| Keywords: | Great Dyke of Zimbabwe rhythmic sequence lateritic nickel landform vegetation |
