In the coastal area of Southern Fujian,the late Pleistocene sediments have a wide distribution (Fig.1).The late Pleistocene strata are mainly composed of following sediments in ascending order:Dgrey medium-fine sand,2)black mud or peat,and 3)yellow sand and sandy clay.The other possible late Pleistocene deposits,so-called "Old Red Sand",are the semi-cemented,well-sorted,and red quartz silt-fine sand.These deposits are distributed over the bays and gullies of mainland and the islands,and constitute the second...

In the coastal area of Southern Fujian,the late Pleistocene sediments have a wide distribution (Fig.1).The late Pleistocene strata are mainly composed of following sediments in ascending order:Dgrey medium-fine sand,2)black mud or peat,and 3)yellow sand and sandy clay.The other possible late Pleistocene deposits,so-called "Old Red Sand",are the semi-cemented,well-sorted,and red quartz silt-fine sand.These deposits are distributed over the bays and gullies of mainland and the islands,and constitute the second terrace,tiebar and other littoral accumulation landforms.In this paper,a number of natural outcrop sections of late Pleistocene strata have been described and drown in Fig.2.Based on the sedimentologic and geomorphologic investigation in the field and the data of 14C dating (Table 1),analyses of foraminifers and ostracods (Table 2) and pollen analysis (Table 3),the following conclusions can be obtained:1.The grey and yellow sand and sandy clay intercalated with black mud or peat belong to the late Late Pleistocene,i.e.the middle and late pleni-glacial substages of the last Glacial Stage,between about 40,000 and 16,000 years B.P..2.The grey and yellow sand and sandy clay,especially the black mud or peat,of the late Late Pleistocene are mainly the deposits of marine-land transitional facies,in part the littoral,and in part lake and swamp facies.3.On the whole,the climate of the late Late Pleistocene was warm and humid,but sometime cooler and drier.4.The "Old Red Sand" is the littoral sediments which were deposited under the heat and humid climate.It might be deposited during the late stage of Late Pleistocene,but the possibility of forming in the earlier period can not be ruled out.

本文对闽南沿海晚更新世沉积的分布特征和主要的地层剖面进行了描述,并根据野外沉积与地貌观察及~(14)、微体古生物与孢粉分析资料,对上述地层与沉积的年代、成因与古气候状况进行了分析与讨论

In this paper, θ-value of free diffraction is analysed with the principles of triangle and spherical surface triangle. Then,the distance between the distance spacings of every point is calculated with Bragg equation and the relative intensity is estimated throught the black degree of point.The method may be used to analyse the mineral grains of which the size is bigger than 0.2mm. Thus, the problem of analysing has been solved, a little amount of samples. The advantages of the method is using less samples,...

In this paper, θ-value of free diffraction is analysed with the principles of triangle and spherical surface triangle. Then,the distance between the distance spacings of every point is calculated with Bragg equation and the relative intensity is estimated throught the black degree of point.The method may be used to analyse the mineral grains of which the size is bigger than 0.2mm. Thus, the problem of analysing has been solved, a little amount of samples. The advantages of the method is using less samples, analysing rapitly, not damaging the samples'outline form in analysis. After analysis, the samples may be kept for other usage.

本文利用三角与球面三角的原理,解析出任意衍射斑点的Q值,然后通过布拉格方程计算出各斑点的面网之间的距离d;并利用斑点的黑度估计相对强度。本法对于粒度大于0.2mm的矿物颗粒即可作物相分析。解决了微量样品的分析困难问题。该方法的优点:样品用量少、分析速度快,在分析过程中不破坏样品的外形,在分析完成之后,样品尚可留作它用。

The gouges have an important influence on the movement of fault. In this paper, after exploring the structural position, occurrence, distribution, deformed characters and composites of the minerals in black clay band extending 14km long on the western segment of the 1920 Haiyuan earthquake faulting belt, the origins and roles of the minerals during the preparatory process and rupture of the Haiyuan earthquake are discussed.The analysis both in laboratory and field shows that the black clay is not the products of the violent offset of the Haiyuan earthquake, but: formed early at the end of palaeozoic, and spread at least 3-4.3km deep.The black clay consists of illite(50%); kaolin(26%); chlorite(15%); moctmorillo-nite(3%), etc. According to the laboratory results, they as 'stress adjustment element" and "stopping crack" in the process of the Haiyuan earthquake.

断层面上的断层泥对断层的运动方式是一个很重要的影响因素。本文在查明1920年海原地震断裂带西端14公里长的黑色粘土矿物的构造部位、产状、分布、变形特征、性状和组成成分与分量之后,讨论了黑色粘土矿物的成因及其在海原地震蕴育破裂过程中的作用。 野外和室内的资料分析结果表明:黑色粘土矿物不是1920年海原地震强烈错动时的产物,远在早更新世以前古生代末就已形成。其至少延深到3—4.3 公里以下。据多种方法的综合分析,矿物成份主要为伊利石+高岭土+绿泥石+朦脱石、石英等,其含量分别为56%,26%,15%和3%。按照T·Shimaoto 和J·M·Logan 的实验结果,它在1920年海原地震的蕴育中可能起了“调整单元”与“终止破裂”的作用。
