Geological Features of the Tangjiawan Vanadio-Titano-magnetite Deposit in Miyi, Sichuan

唐家湾钒钛磁铁矿位于扬子陆块与松潘—甘孜活动带的西南结合部康滇断隆带中段南部、安宁河断裂西侧。矿体产于华力西期基性超基性岩体中,矿石矿物主要为钛磁铁矿、钛铁矿等,多具海绵陨铁结构,在岩浆结晶晚期形成,围岩为印支期正长岩。矿床成因为晚期岩浆矿床。

The Tangjiawan Vanadio-titano-magnetite deposit lies in the south of middle section of the Kangdian fault upwarping belt and on the western side of the Anninghe Fracture zone. The orebodies are confined to Hercynian ultrabasic rock. The ore consists of titanomagnetite and ilmenite with sideronitic texture. The deposit belongs to late magmatic ore deposit.
