花岗闪长岩 花岗闪长岩是地下岩浆在地壳深层3千米以下，缓慢冷却形成的火成岩，属深成岩。因其含有相对丰富的角闪石和斜长石，得名花岗闪长岩，它颜色黑白相杂。九华山的花岗闪长岩是在1.4亿年前由太平洋板块和欧亚板块碰撞，引起岩浆上涌冷却后形成，它主要分布在九华山脉两侧，构成青阳岩体。 Granodiorite  The granodiorite is a plutonite resulting from the slow condensation and crystallization of magma produced inside the crust of 3000 m depth. The name of granodiorite is because of abundant black hornblende and white plagioclase. The granodiorite in Jiuhuashan was the condensed product of magma caused by the collision of the Pacific Plate with the Eurasian Plate 140 million years ago. It constitutes the main part of Qingyang rock body and can be found at the foot of the Jiuhuashan range. 正长花岗斑岩 正长花岗斑岩，是岩浆在近地表冷却形成的火成岩，属浅成岩。它因具有斑状的钾长石晶体，所以称为正长花岗斑岩，颜色肉红。它是1.2亿年前岩浆上涌并穿插到花岗闪长岩岩体内，形成岩墙或岩脉，它主要分布在九华山甲子岭到方家里一带。 Syenogranite Porphyry  Syenogranite porphyry, a hypabyssal rock, is an igneous rock formed by condensation of magma near to the surface. It is of flesh pink color and contains porphyritic potassium feldspar crystals. The dyke was formed by magma upwelling and intruding into the granodiorite rock body 120 million years ago. It can be found mainly in the Jiaziling-Fangjiali area in Jiuhuashan Geopark.
