摘　　要：在广泛搜集前人资料的基础上,结合云南省武定县梅子箐钛铁砂矿勘探、云南省武定县长冲钛铁砂矿普查获得的资料,将云南省武定地区的基性侵入岩钛铁砂矿风化壳剖面,自上而下划分为红土化带粉土、全风化带砂质粉土、半风化带砂土及微风化-末风化基岩。划分4个带的土体类型、矿物特征、主量元素有较明显的差别。Based on the extensive collection of previous data【1-4】,combining with the data obtained from the exploration of Meiziqing ilmenite placer,and the survey of the Changchong ilmenite placer in Wuding County,Yunnan Province,The weathering crust profiles of basic intrusive rocks in Wuding area can be divided into 4 zones from top to bottom:the red soil layer,the completely weathered layer,half weathering layer and weakly weathered layer,respectively.The obvious difference about soil types,mineral characteristics,and major elements of these four zones is existed.
