granodiorite porphyry meaning in Chinese

花岗闪长斑岩

( 4 ) the trace elements and ree geochemistry of the tongchang granodiorite porphyry indicate , there exists the reaction between the porphyry and the hydrothermal fluid . the hydrothermal fluid was cl - enriched solution , and flowed from the porphyry center to contact zone
( 4 )德兴铜厂斑岩体微量元素和稀土元素地球化学特征表明，该岩体发生了流体?熔体作用，分异出来的流体是一种相对富氯的流体，同时成矿流体的流向是从岩体中心向接触带方向流动。
This process was propitious to enrich , activate , transport the copper . in different alteration granodiorite porphyry , sio2 , k2o , cu , mo are depleted in the fresh and weakly altered rock , and are enriched in the strongly altered rock , cl is also enriched in the strongly altered rock . but na2o and fe are extracted from the porphyry into the ore - forming fluid , especially the presence of fe is in favor of cu deposition
在铜厂岩体不同的蚀变带中， sio _ 2 、 k _ 2o 、 cu 、 mo等从新鲜斑岩甚至弱蚀变带中带出，而在强蚀变带强烈富集， cl同样有在强蚀变岩石中富集的趋势；而na _ 2o 、 fe从斑岩体中带出，进入流体相中，流体中大量fe的存在，有利于铜的沉淀、富集成矿。
