例句与用法
- 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
最后,综合本区幔源矿物和地幔岩石的特征以及地球物理资料,得出如下结论:本区上地幔的物质组成有尖晶石二辉橄榄岩、二辉岩、单斜辉石岩、纯橄榄岩、方辉橄榄岩、石榴石二辉橄榄岩、金云母二辉橄榄岩、榴辉岩;与中国东部以及华北地台上地幔相比,研究区上地幔具有富集主元素中相容元素和亏损其中的不相容元素的特征,局部熔融程度较高;上地幔存在横向和纵向的不均一性,从西部的克里阳到喀拉喀什河和玉龙喀什河流域, al和lree富集程度呈下降趋势,不同来源的相同矿物中主元素的含量差异较大;地质历史时期这里可能发生过地壳俯冲并产生壳幔混合作用;玄武岩浆的起源深度73km ;从幔源重砂矿物的温压估算结果,可以推断出岩石圈厚度可达204 . 9km ;综合岩石圈物质组成特征、岩石圈热状态、地幔温压状态、氧逸度以及幔源岩石和幔源矿物的化学成分,认为研究区具备了金刚石成矿地幔地质条件。 - It is difficult to conform the derivations of the native heavy minerals , so the author assumes corresponding procedures as follows to accomplish the research task : firstly , according to the composition typomorphic peculiarities of minerals deriving from mantle , the author selected a part of minerals as preliminary reseach objects from the native heavy minerals and then further investigate the mantle ones and their host rocks in two ways : one is the method of comparation with the corresponding minerals of rocks deriving mantle in the research field and other places ; anorther is the method of multivariate statistical analysis
本次工作为了尽可能地排除非幔源矿物的干扰,根据陈光远( 1990 ) 、潘兆橹( 1994 )等学者有关矿物成分标型的论断,筛选出地幔特征元素含量较高的重砂矿物做为初步研究对象,为达到研究目的采取了如下方法:与区内已发现的幔源岩石(如钾镁煌斑岩等) 、国内外有代表性的碱性玄武岩、金伯利岩、钾镁煌斑岩的深源包体中的相应矿物进行对比研究的方法;多元统计分类的方法。 - Because of the absence of mantle xenoliths and xenocrysts , it is the first time that this paper looks on the native heavy minerals deriving from mantle , which were collected at the terraces of the two rivers , kalakshi river and yulongkashi river , as objects and takes into account the geochemical characteristics of the rocks deriving from mantle such as keliyang lamproite and so on to study the composition of lithospheric mantle , the characterics of palaeozoic era lithospheric mantle , mantle thermal state , and diamond metallogentic mantle geological conditions in research field
为达到研究目的,本文首次以喀拉喀什河和玉龙喀什河沿岸阶地的幔源重砂矿物(单斜辉石、铬尖晶石类矿物、钛铁矿以及石榴石)为研究对象,结合钾镁煌斑岩等区内已发现的幔源岩石及其中地幔物质对该区地幔物质的组成、古生代岩石圈地幔特征、岩石圈热状态以及该区金刚石成矿地幔地质条件做了尝试性的研究工作。
