英文
anatectic magma-
Amore 2001 has successfully investigated the gakkel ridge and arctic ocean in vicinity of its geological and geophysical nature, as well as the nature of sea ice and biology in this area. the preliminary onboard petrology and bathymetry results show that the mantle beneath the gakkel ridge with low temperature has only encountered very low degree partial melting during the spreading and there is no any direct relationship between the crust nature and the spreading rate along the gakkel ridge in any simple petrologic way. mantle temperature and fracture zone density also play a major role on the crust nature, besides spreading rate
對所取得資料的初步研究表明gakkel洋中脊之下的地幔僅經受了較低程度的部分熔融,具有較低的溫度。 gakkel洋中脊處的地殼性質和巖漿活動與擴張速率之間不存在任何直接的巖石學相關性,擴張而導致的巖石圈頂部的冷卻並不是決定洋脊處地殼性質的最重要因素。地幔溫度和斷裂帶的存在與否及其密度對地殼性質具有重要的影響意義。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。Strong negative 8 eu shows the granites are high evolved granite. ( 6 ) the tetrad effect of ree and the obvious fractionation between k - rb, y - ho, zr - hf, nb - ta, and sr - eu in the dajishan granites indicate that, the aqueous fluid pays an important role in the evolution of the granites, as well as indicate that there exist enough interaction between peraluminous melt and aqueous magmatic fluid. furthermore the fluorine played a very important role in this process
( 6 )大吉山花崗巖類稀士元素具有「四重效應」配分的特點以及微量元素對kjrb 、 y / ho 、 zr艦f以及nb / ta發生明顯分異,暗示在花崗巖巖漿的演化過程中,經歷了充分的流體一熔體作用,同時分異出大量富含f 、 w等礦化劑元素和成礦元素的熱液流體,致使鎢礦的形成。Early on, dense iron sank out of the magma oceans to form the metallic core, liberating enough gravitational energy to melt the entire planet
更早期的時候,較重的鐵自巖漿海中析出下沉,漸漸形成了金屬成份的地核,下沉時釋放出的重力位能足以把整個地球再次熔融。Under the guidance of synthetic information theory, the authors have quantitatively appraised the three types of gold deposits in the area using the method of logical information, that is, remelted - magmatic hydrothermal, syntecnic magmatic hydrothermal and volcanic sub volcanic hydrothermal gold deposits. 12 regions are predicted to be most perspective
在綜合信息成礦理論的指導下,對巖漿重熔熱液型金礦、巖漿同熔熱液型金礦床以及火山一次火山熱液型金礦床利用邏輯信息法進行了定量預測,總共預測出12個最有遠景的區域。分享友人
