摘要
富宁地区里达断裂东侧出露大量的中三叠世印支期第一期第四亚期侵入的辉长辉绿岩体,经过漫长的风化、水解作用,岩体岩石结构构造遭受破坏,钛铁矿、钛磁铁矿、金红石等矿石矿物从原岩中彻底解离,从而形成了易开采利用的辉长辉绿岩风化壳型钛铁矿(砂)矿床。
There are a lot of Middle T Indosinian 1st stage 4st substage gabbro-diabase intrusion bodies, which have been damaged by the long-term weathering, hydrolysis. Ilmenite, titanic magnetite and rutile, etc are de- tached from the original rock, result in the formation of the easy mining ilmenite placer of gabbro-diabase weathe-ring crust type.
