mineral enrichment 中文意思是什麼

The results indicate that : 1. the main physical and chemical characteristics vary regularly : with rising of the altitude, there is a transition from silt > sand > clay to sand > silt > clay in the mechanical composition ; the argic horizon emerges below the altitude of 1600 meters ; the content of organic matter is enrichment, the content of organic carbon of epipedon is higher than 20 g / kg, while the content of organic carbon increases with increasing of altitude, and in the altitude of 3500 - 3700meters, the soils under the meadow have the maximum content organic carbon ; the soils appear acid - slightly acid reaction, the ph decreases appreciably and acid strengthen with increasing of altitude ; the soils higher than the altitude of 2500 meters are base unsaturated, indicating the soil leaching is strong, the ph and bs are distinct plus correlated ; the contents of sio2, al2o3, and fe2o3 of the soil body and clay are all relatively stabilization ; in the soil body, the content of sio2 is much high and cao is very little, the total contents of sio2, a12o3 and fe2o3 occupy 92 % of the mineral parts, the sequence of mineral elements is : sio2 > al2o3 > fe2o3 > k2o > mgo > cao > tio2 > mno

研究結果表明： 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化：隨海拔高度上升，機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒，海拔1600m以下出現粘化層；土壤有機質豐富，表層有機碳含量一般在20g kg以上，有機碳含量隨海拔高度升高而相應增加，海拔3500 3700m的灌叢草甸植被下有機碳含量最高；土壤呈酸性或微酸性，並隨海拔上升， ph值略微降低，酸性增強，海拔2700m以上的土壤多呈鹽基不飽和狀態，表明土壤淋溶作用較強， ph值和鹽基飽和度呈極顯著正相關；土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定，土體中sio _ 2含量較高， cao含量較少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ，礦質元素含量的順序依次為： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。

Pilsenite is a rare mineral and its information is deficient. the first found pilsenite in china is in gaozhuang, henan province. pilsenite, associated with pyrrhotite, pyrite, hessite, gold, produced in pyrrhotite - polymetallic stage. three bismuth - tellurides produced in gaozhuang are well concordant with the standard pilsenite in composition, and other three are different from any of known bismuth - tellurium minerals. single crystal diffraction were made on a larger mineral grain of pilsenite. au growth and decline together with bi and te in ores and wall - rocks, which suggests that bi and te play a important role in migration and enrichment of au

經電子探針分析，高莊金礦有多種鉍碲化物，有三粒礦物的成分與標準葉碲鉍礦完全一致。對一較大顆粒的葉碲鉍礦做了單晶x射線衍射分析。 au與bi在礦石和圍巖中的含量呈共消長關系， te與bi可能對au ag的遷移富集起了重要作用。

In the west qinling, qilian and longshoushan metallogenic zones, some larger - ultra larger mineral deposits were formed throughout a model of " bearing " in long course of geological evolution. studying their geologic setting of " formation " and condition of late " development " would help us to objectively realize rules for the metallization and enrichment and define reasonable thinking for research and plan for exploration

甘肅西秦嶺、祁連、龍首山等成礦帶的大型-超大型金屬礦床，是在地質構造發展演化過程中「生長」而成的；研究分析其「生」成背景與後期成「長」的條件，有利於客觀認識成礦與富集規律、合理確定研究思路與勘查方案等。

In this dissertation the author mainly discussed the tectonic evolution of the fuxin au - concentrating area in the north segment of the yiwulushan mountains. the character of the regional structure and its relation to the enrichment of gold deposits since mesozoic were deeply gone into by the author to provide the basis of regional ore - forming structures for the planning and evaluation as well as exploration of mineral resources

論文對醫巫閭山北段阜新金礦集中區的構造演化歷史，尤其是中生代以來的區域構造特徵與金礦形成富集的關系作了深入的研究，以期為本區資源規劃、評價及礦產勘探工作提供區域成礦構造學方面的依據。

Cu - ni sulfided mine complex locate in baimazai of jinping county is sub alkali iron - super iron, it ' s zoning is clear and it ' s ni - cu - co melting first and enrichment, its rare earth is rich in right lean light rare earth, but eu in olive rock is serious to be bad, gd - tb is tittles negative abnormity. above - mentioned show that the mineral is cone from mantle, and didn " t mix with crustal substance, and continent tholeiite magma turning into continent tholeiite emplacement after by surging

金平白馬寨銅鎳硫化礦床雜巖體分帶明顯、屬亞堿性鐵質-超鐵質巖、具ni - cu - co三元素先熔離，后富集的規律、稀土配分為右傾斜輕稀土富集型，但橄欖巖銪虧損顯著， gd - tb微小負異常，顯示成礦物質來源地幔，與地殼物質無混染和大陸拉斑玄武巖漿上涌后變為大洋拉斑玄武巖漿侵位特點。

It is very important that the understanding of regional metallogenic rules should be emphasized and the thinking of exploration and research opened up. in this thesis, mainly metallogenic types, tectonic setting, space - time distributions and the ore - controlling and metallogenic conditions for copper ore deposits in gansu province are studied on based inducing past formation which basic theories and methods of the modern geology, mineral deposits and related learning are applied and a serious of formation synthesized throughout depending on guide of regional. - metallogenic theories. a rule of development, enrichment and regional metallogeny would be preliminary summaries in terms of analyzing mineral prospecting for gansu ' s copper, gold and polymetallic minerals, and the relation between the indosinian - yanshan structural - magmatic activities is studied and exploration prospect and positions analyzed as well as a new countermeasure and thinking about research for minerals in this area be suggested
