Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits
最後，綜合本區幔源礦物和地幔巖石的特徵以及地球物理資料，得出如下結論：本區上地幔的物質組成有尖晶石二輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲母二輝橄欖巖、榴輝巖；與中國東部以及華北地臺上地幔相比，研究區上地幔具有富集主元素中相容元素和虧損其中的不相容元素的特徵，局部熔融程度較高；上地幔存在橫向和縱向的不均一性，從西部的克里陽到喀拉喀什河和玉龍喀什河流域， al和lree富集程度呈下降趨勢，不同來源的相同礦物中主元素的含量差異較大；地質歷史時期這里可能發生過地殼俯沖並產生殼幔混合作用；玄武巖漿的起源深度73km ；從幔源重砂礦物的溫壓估算結果，可以推斷出巖石圈厚度可達204 . 9km ；綜合巖石圈物質組成特徵、巖石圈熱狀態、地幔溫壓狀態、氧逸度以及幔源巖石和幔源礦物的化學成分，認為研究區具備了金剛石成礦地幔地質條件。The research results mainly show : ( 1 ) the ecological degradation characteristics of wuxi county include : some soil is thin and barren and its water and fertility conservation abilities are poor, gradual degradation of soil results in decrease of vegetation diversity and the vegetation community structure gradually inclines tc simplicity from complexity. the types of soil and water loss in wuxi county mainly involve surface erosion and gully erosion. according to investigation, surface erosion area occupies 80 % or so or erosion area, in which the slope farmlands surface erosion area accounts for about 70 % of farmland erosion area
研究結果主要包括： （ 1 ）巫溪縣生態退化特徵表現：作為生物生長基質的部分土壤薄而貧瘠，保水保肥能力差，部分地區基巖裸露，土壤的不斷退化導致植物種多樣性減少，植物種群結構逐步由復雜趨向簡單化；縣內水土流失的類型主要包括面蝕和溝蝕兩大類，據調查，面蝕面積占侵蝕總面積的80左右，其中坡耕地面蝕佔耕地侵蝕面積的70左右。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。Now, sr isotopes can be used not only to constrain the origin and evolution of magma and hydrothermal ore - forming solutions, calculate the scale and degree of lithogenesis and ascertain the relations between fluids and rocks, but also to study sea - level fluctuation, plate movement, ocean - floor spreading and lithogenic evolution
現在，鍶同位素不僅在示蹤巖漿及成礦熱液的來源和演化、計算晚期成巖改造作用的規模和程度及流體/巖石比等方面已趨于成熟，並且越來越廣泛運用於海平面變化、板塊活動、海底擴張、成巖演化等方面的研究。Beishan deposit which located on the most north part of yinshan deposit has an independent change trend high to low in ore - forming temperature with from east to west in pace. this indicates that quartz porphyry 5 # may be the mineralization center of beishan deposit
本文通過流體包裹體顯微測溫學研究得出初步結論，北山礦床成礦溫度從東到西呈由高到低的變化趨勢，表明北山的5 #石英斑巖是北山礦床成礦作用的中心。Cl, s, f, tongchang porphyry copper deposit and the dajishan tungsten deposit are selected as the studying objectives, detailed investigations have been conducted into the geological and geochemical characteristics of the granitic rock, biotite, trace element and ree geochemistry, fluid inclusion geochemistry and the partitioning coefficients of the f, cl, cu, w. based on these data, the following conclusions are drawn : ( 1 ) fluorine can reduce the viscosity and density of magma, temperature of solide - liquidus line and change the melt frame, but cl has little effect on the melt
主要的認識如下： （ 1 ） f在花崗質巖漿中，可以降低巖漿的粘度、密度、固液相線溫度、改變熔體結構，而cl對熔體結構沒有多大的影響。 f在流體?花崗質熔體相間，絕大多數配分系數小於1 . 0 ，趨向于熔體相中配分， d _ f隨體系中f濃度的升高而增加。According to the forecasting analysis results, the displacement of the rock mass is mainly trending to steady rheological status. different positions of the opening has different rheological characteristic and the time of reaching steady rheological status is different : rock mass at the foot of the opening has evident accelerated rheological phenomenon
根據預測趨勢曲線看，洞室圍巖的流變特性明顯，變形主體上能保持在穩定流變階段；不同監測部位的流變特性是不同的，它們達到穩定流變的時間也不同。分享友人
