太和层状镁铁质-超镁铁质岩体位于峨眉山大火成岩省内带,是几个赋存超大型钒钛磁铁矿床的层状岩体之一。太和岩体呈单斜层状产出,长约3 km,宽约2 km,厚约1.2 km左右,倾向东南,倾角50°~60°。锆石U-Pb年龄分析表明太和岩体的结晶年龄在259±3 Ma,这说明太和岩体形成于峨眉山地幔柱岩浆活动期。根据矿物组合以及矿物含量、结构特征等,岩体从下向上划 The Taihe stratiform mafic-ultramafic mass is located in the belt of the Emeishan large igneous province and is one of several stratified rock masses that host very large vanadium-titanium magnetite deposits. The Taihe rock mass is monoclinic with a length of about 3 km, a width of about 2 km and a thickness of about 1.2 km, with a southeasterly dip angle of 50 ° -60 °. Zircon U-Pb age analysis shows that the crystallization age of Taihe pluton is 259 ± 3 Ma, indicating that the Taihe pluton was formed during the Emeishan plume magmatic activity. According to the mineral assemblage and mineral content, structural characteristics, rock mass is planted from the bottom up
