摘要
Late Jurassic intrusive rock in Xiuyan area belongs to the Calc-alkaline potassic peraluminous rock types,divided into two stages according to the lithology and contact relationship. Rock types evolved from the early medium-fine grained biotite (hornblende) monzonitic granite to the late fine grained hornblende biotite monzonitic granite the biotite composition evolved from the early siderophyllite to the late ferruginous biotite. Didjumolite sort decreases gradually. Accessory minerals are diochrom-apatite type.
