新鮮巖石 的英文怎麼說
中文拼音 [xīnxiānyándàn]
新鮮巖石
英文
fresh rock-
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。According to the constructive principles of these diagrams, the following aspects must be thought carefully : the rock types to be studied must be the same or nearly the same as those that can be discriminated by the diagram ; to avoid mixed or incorrect signals that could be produced, two or more such diagrams shall have to be jointly used ; for special rock types, such as a - type granites or potassic igneous rocks, special discriminative diagrams have to be determined and selected respectively ; the samples to be studied can not be altered ; in general, the diagrams must be used carefully with archean samples ; the petrotectonic assemblage or an expert system are recommended to be used together with the discrimination diagrams
強調指出：所採集的樣品必須新鮮（無蝕變或極弱蝕變） 、非堆晶的巖石；選擇的判別圖解必須與判別的巖石類型相一致，即對花崗巖類要用花崗巖的判別圖解，不能用玄武巖的判別圖解；對特殊類型巖石要選擇專門用於該類型巖石的判別圖解，如堿性花崗巖，鉀質火成巖；要應用多種圖解綜合判斷；不能用單個樣品，而應作多個樣品分析；要注意所選擇判別圖解的特別說明等。On the other hand, if the new lava carries the fingerprint of fresh magma from the mantle and does not contain old zircons, then it very likely came from a large volume of new magma that has filled the chamber from below
不過，如果新熔巖顯示的特徵，是來自地函的新鮮巖漿，而且不含古老的鋯石，那麼它的來源很有可能是：從巖漿庫下方填充上來的大量新巖漿。
