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。Although the available content of p in the soil was above the critical level, it showed deficiency in the greenhouse experiment, probably because of the strong adsorption by the soil, and the high requirement of the sorghum plants to p from the small volume of soil
盡管磷在土壤中的有效含量高於虧缺臨界值,在溫室試驗中卻表現出缺乏,很可能是由於土壤對磷的吸附很強,同時盆栽土壤體積小,高粱吸收磷強度大。2. according to the weighted average, soil co2 concentration is 0. 58 - 13. 29 times of that in atmosphere and is relatively lower than similar research, meanwhile, soil co2 concentration in profile varied irregularly, which possibly is due to the chemical and physical characteristic of loess soils, season change and arid climate etc. the variation of soil co2 concentration in profile is mainly controlled by soil temperature and soil moisture, in contrast with soil temperature, the control role of soil moisture is minor. in conclusion, in order to have a good command of the distribution and change rule of soil profile co2 concentration as well as its effect factors, multi - point and successive location experiment should be made, meanwhile establish indoor soil - pillar monitoring experiment
土壤co _ 2的濃度約為大氣co _ 2濃度的0 . 58 ? 13 . 29倍與同類研究相比要低,這是與黃土的土質特性,觀測期又逢特別乾旱年制約了土壤微生物的活動,再加上土壤中有機質虧損,養分不足造成的;土壤co _ 2含量的變化是隨溫度的升高而升高,在夏季達最高值,冬季最低;在土壤co _ 2濃度變化的影響因子溫度和水分中,溫度的影響作用高於水分;土壤剖面co _ 2濃度隨著深度增加,總的變化趨勢是遞增的,但也有反復,甚至有的順剖面而下幾乎保持一恆值,這與季節變化和黃土自身結構的通透性以及在觀測期內的乾旱氣候等條件有關。
