Abstract:一.引言这篇报告只限于笔者早年在准噶尔盆地东部的一段地质工作,叙述沿奇台县子午线由天山到北塔山的地质与地貌,涉及的范围是东经89°—91°北纬43°21′—45°20′,南北长约为320公里的地带。笔者除了沿着一条路线穿行以外,为了多了解一些地质情

Abstract:引言这个报告是最近两年作者在整理新疆野外工作资料后所写的两篇综合报告,第一篇是准噶尔东部地质,第二篇是济木萨县三台以南大龙口及水西沟一带的地质、岩层与构造。前一地区代表陆台性质,后者则属于天山北部的山前拗陷带。

Abstract:在倾斜的平面状的隔水层上的均质的土中流动着的潜水或不承压水,它的流量的计算方法有多种多样。这反映了这个命题,在生产实践上,具有相当大的意义。例如计算水库的渗漏时,如果库岸的地层是倾斜的,那末就需要运用这些方法。

Abstract:一.前言二叠纪地层在中国南部分布极为普遍,几乎每省都有它的出现。这一纪地层以产锰矿、石灰岩、煤、耐火材料以及铜、钴(西南玄武岩系中)等著称,近年来并发现其中有磷矿层,因此在祖国社会主义建设中有很大经济价值。关于中国南部二叠纪地层和动

Abstract:Strata of Permian age are fairly well developed in the Liangshan region,S. Shensi. They differ in some degree from those of South and SouthwesternChina, particularly in their upper portions which are almost entirely composedof limestones. The subdivisions adopted here are as follows(in descending order): Upper Permian-Lopingian

Abstract:一.引言月门沟系(太原统及山西统之合称)为中国北部最重要含煤地层之一。其在华北分布之广、在地质史划分上的重要以及所含化石的众多,不只华北其他各时代的地层无出其右,即在全世界的同期沉积中,也不多见。此系在地层及古生物方面的意义,数十年来经中外学者各方面的研究,早已大著于世;其中所含工业用煤的丰富,就近年来的勘

Abstract:In the consideration of the Permo-Carboniferous history of Eastern Asia,the Yuehmenkou series stands out as an unit of wide extent both stratigraphicallyand palaeontologically. The name Yuehmenkou series was first given by Dr.Norin in 1922 as a whole coal-bearing formation of Central Shausi, which wasdivided into two parts--a lower, the Taiyuan series, and an upper, the Shansiseries. The type-locality of this formation is the Yuehmenkou, in the WesternHills of Taiyuan. The Taiyuan series is composed mainly of shale, variegatedclay, sandstone, important coal seams and a few interstratified marine lime-stones. The same may be said to be the case in the Shansi series, but thereseems to be only one layer of marine limestone, the Tungtayao Limestone, lo-cally developed at the lower part of this series. The preliminary study of thepalaeozoological remains contained in the marine beds of this formation, leadsProf. Grabau and Dr. Norin to consider its lower part, i. e., the Taiyuan seriesas representing the transition from Viseen to Moscovian, without being as yettrue Moscovian, and its upper, i. e., the Shansi series to be of Permo-Car-boniferous age.

Abstract:长久以来地质学家对定向压力(stress)在矿物形成过程中的作用有着不同的看法。如哈克尔把云母、绿泥石和脆云母都算作所谓定向压力矿物(stress mineral),即它们的稳定范围(主要对压力和温度而言)因有了定向压力的参加而得以扩充。拉尔
