不对称相带的安基山石英闪长玢岩—花岗闪长斑岩侵入体的形成,是浅部岩浆房内对流循环作用的结果,岩浆由顶部向下、边部向里逐渐固结成岩,成岩过程中无明显重力分离。由于岩浆体间歇性上升,早期结晶尚未固结的角闪石英闪长玢岩岩墙,晚期沿着冷却边缘裂隙定位,最后为似斑状花岗闪长岩固结。岩体具水平分带和垂直分带。斜长石的韵律环带反映了在超冷却作用或对流循环过程中发生的组分变化。 The formation of asymmetric facies Anji quartz diorite porphyrite-granodiorite porphyry intrusion is the result of convective circulation in the shallow magma chamber. The magma gradually declines from top to bottom, , No significant gravity separation during diagenesis. Due to the intermittent increase of magma bodies, the amphibole quartz diorite rock wall, which had not been crystallized early, was located late along the cooling margin fissure and eventually consolidated into plagioclase granodiorite. Rock mass with horizontal and vertical zoning. The rhythmic zone of plagioclase reflects the compositional changes that occur during supercooling or convection cycles.
