altered rock
解釋
蝕變巖石-
Ultramafic rock fragments, which almost is altered to ophite, distributed in structural zone and displayed structural lens. so far, 9 fragments were discovered and mapped in nujinshan and bujing area ultramafic rock can be divided two kinds according to it ' s geochemical characteristics. one can be correlated with metaperidotite, which represented residual part that primary pyrolite underwent moderate partial melting, from some representative ophiolite melange in the world
按超鎂鐵巖類的地球化學特徵可將其劃分為兩類：一類具有較高而穩定的mgo 、較低的al _ 2o _ 3 、極低的cao ， m f值為8 . 0 ? 8 . 4 ，按標準礦物組合進行分類可定為方輝橄欖巖，且均為fa _ （ 100 ） 、 en _ （ 100 ）的鎂質端元組分；可與世界上一些典型的蛇綠巖套中變質橄欖巖進行對比，代表了原始地幔中等部分熔融作用后殘余物。 -
This is due to the higher weathering resistance of hydrothermally altered rock.
這是由於熱液蝕變巖石具有較高的抗風化力的緣故。 -
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。 -
Located in the central part of the qianhe - miaoling - manyu metallogenic belt, the xiaonangou deposit in songxian county is a typical tectonic altered rock type gold deposit
摘要嵩縣小南溝金礦床位於前河廟嶺蠻峪成礦帶中部，是典型的構造蝕變巖型金礦床。 -
It was shown by field investigation and lab tests that the types of altered rocks were mostly those of montmorillonitization, and the altered clay mineral was mainly pure montmorillanite, which rendered the altered rock both soft and expansive
野外地質調查和室內測試表明：滇藏鐵路滇西北段出露的多為蒙脫石化蝕變巖帶，蝕變巖的黏土礦物組成絕大多數都是單礦物的蒙脫石，導致該地區的蝕變巖既是強度極低的軟巖，又是典型的膨脹巖。 -
According to the comparison and analysis of mineral composition and geochemical characteristics of trace element, sulfur isotope, hydrogen and oxygen isotope, lead isotope and rare earth element in the gold ore and the altered spilite from the deposits of huachanggou gold mine, it was confirmed that the gold ore had obvious succession of the basic igneous rock
摘要通過對鏵廠溝金礦床金礦石和蝕變細碧巖礦物組成、微量元素、硫同位素、氫氧同位素、鉛同位素及稀土元素地球化學特徵地對比分析，得出金礦石對該基性火山巖存在明顯的繼承性。 -
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。 -
The extraction of mineralized and altered rock information from remote sensing image based on svm
東昆侖五龍溝金礦圍巖蝕變的遙感識別 -
Based on such characteristics of the xiaonangou gold deposit as trace element associations, horizontal zoning, vertical zoning, element contrast values, orebody lateral plunging, and attitudes and sizes of orebodies, this paper deals tentatively with the geochemical anomaly pattern of tectonic altered rock type gold deposits, with the purpose of establishing ore - prospecting criteria for ore exploration work of this area
以小南溝金礦床中微量元素組合關系、水平分帶、垂直分帶、元素對比值、礦體側伏、礦體產狀和規模等特徵為例，探討構造蝕變巖型金礦床的地球化學異常模式，以期建立地質找礦標志，指導本地區的找礦工作。
