granodiorite porphyry 中文意思是什麼
-
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
在銅廠巖體不同的蝕變帶中， sio _ 2 、 k _ 2o 、 cu 、 mo等從新鮮斑巖甚至弱蝕變帶中帶出，而在強蝕變帶強烈富集， cl同樣有在強蝕變巖石中富集的趨勢；而na _ 2o 、 fe從斑巖體中帶出，進入流體相中，流體中大量fe的存在，有利於銅的沉澱、富集成礦。 -
( 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 ）德興銅廠斑巖體微量元素和稀土元素地球化學特徵表明，該巖體發生了流體?熔體作用，分異出來的流體是一種相對富氯的流體，同時成礦流體的流向是從巖體中心向接觸帶方向流動。
