摘要
腊坪地区TiO2区域高值,有利于钛铁矿形成富集。对三类主要岩浆岩中TiO2含量与重砂淘洗砂矿样含矿率比照,认为辉长岩是钛铁砂矿含矿母岩,且与地形地貌及风化次生堆积条件有关。
The regional high TiO2 value in Laping area is advantageous to the enrichment of ilmen- ire. According to the comparison between TiO2 contents in 3 main magmatites and ore - bearing ratio of heavy sand sample of placer, we think that the gabbro is the mother rock of ilmenite placer, which is in relation with landform and secondary accumulation condition.
