摘要
云南钛铁砂矿床分布广、规模大,具有近、浅、易、富,找矿标志明显、勘查成本低、矿石易采易选等特点,其含钛铁矿基岩为海西期基性岩。文章对云南风化壳型钛铁砂矿床的分布特点、地质特征进行了总结和研究,在此基础上对该类矿床的成因进行了探讨。
The Ti-Fe placer deposits in Yunnan,which are large in scale and widely distributed,are characterized by ＂short distance,shallow burial depth,easily exploitation,resource abundance＂,and have advantages such as obvious prospecting clues,low exploration cost,easy mining and easy milling.The bed rocks in which Ti-Fe ores are contained are Hercynian basic rocks.Based on the findings of researches on the distribution features and geological characteristics,the genesis of weathering crust type Ti-Fe placer deposits in Yunnan is investigated.
