A brief outline based on foreign literature published in 1951-1960 is given of the advances in chemical oceanography within the last tea years under following topics: (1)Chemistry in relation to marine organisms; (2)Marine geochemistry of clements; (3)Equilibriums and kinetics of chemical processes in the sea; (4)Physico-chemical properties of sea water; (5)Chemistry in relation to hydrology; (6)Chemistry of sea sediments.

本文根据1951-1960年主要文献,对国外近十年来化学海洋学主要发展情况做初步的概括介绍,除对整个学科的总的特点和总的趋势加以讨论外,并将近十年主要工作分为:(1)海洋生物和化学的关系;(2)元素在海洋中的地球化学;(3)海洋中化学过程的平衡和动力学;(4)海水物理化学性质;(5)化学组成与水文的关系和(6)海洋沉积物化学等六个方面做重点介绍。

By using of the accumulative curves of log probability of the particle size analysis, the authors have investigated more than 300 thin sections of the Paleogenic Funing Group and Taizhou Formation in Kiangsu Province, and Changhe Formation in Chekiang Province. It has been found that this method is fairly effective to discriminate the sedimentary environment of ancient sandstone bodies, though it should be verified by other statistical methods of grain size analysis, such as plots of textural paramenters, C....

By using of the accumulative curves of log probability of the particle size analysis, the authors have investigated more than 300 thin sections of the Paleogenic Funing Group and Taizhou Formation in Kiangsu Province, and Changhe Formation in Chekiang Province. It has been found that this method is fairly effective to discriminate the sedimentary environment of ancient sandstone bodies, though it should be verified by other statistical methods of grain size analysis, such as plots of textural paramenters, C. M. Patterns, as well as by the studies of well log, mineralogy, paleontology and geochemistry, in order to promote the accuracy of interpretation. It is shown from the various plotted graphs that the curves of fluvial sands are dominantly the type curves of two fragments (members), and may be inferred as representing that of deltaic distributary system. Yet there are also curves of three fragments, which may indicate the deposits of torrential rivers. Beach sands have the characteristics of the presence of two saltant components and the absence of suspend component. The constituents of river mouth bar sands and shoreline sands of distributary debouchs are transitional between that of fluvial sands and beach sands. The deposits of levees and crevasse fans consist predominantly of suspend component. It is interesting to note that this method of grain size analysis can, in certain extent, be adopted to interpret the environment of carbonate sands.

Mineralogy method: including the way of formation and the change of minerals ,gas-liguid inclusion of minerals ,typomorphic peculiarity of minerals,typomorphic minerals and mineral paragenesis,etc.,with which the genesis of minerals is studied. 2. Geology methods utilizing the feature of varied geological processes of mineral formation-magmatic process,sedimentation process and matamorphic process,etc.,to treat the genesis of minerals....

The thesis freals chiefly of four methods of studying the genesis of minerals. 1. Mineralogy method: including the way of formation and the change of minerals ,gas-liguid inclusion of minerals ,typomorphic peculiarity of minerals,typomorphic minerals and mineral paragenesis,etc.,with which the genesis of minerals is studied. 2. Geology methods utilizing the feature of varied geological processes of mineral formation-magmatic process,sedimentation process and matamorphic process,etc.,to treat the genesis of minerals. 3. Geochemistry method: This method studies the condition of collection of chemical elements in the earth's crust on the progress of varied geological processes,such as temperature,pressure,acidity and alklinity,etc.,which are the factors of geochemistry. They explain the physico-chemical environment of mineral formation,origin of miner-ogenetic matter and the genesis of minerogenetic fused mass and solution. These factors are used to study the genesis of minerals. 4. physico-chemistry method: It studies the physico-chemical conditions of the formation of minerals. These conditipn s are used to explainfhe g enesis pf minerals.

本文主要讨论成因矿物学的四种研究方法。①矿物学法:包括矿物的形成方式和变化、矿物的气—液包裹体、矿物的标型特征、标型矿物以及矿物的共生组合等问题来研究矿物的成因。②地质学法:是指运用矿物形成的各种地质作用,如岩浆作用、沉积作用和变质作用等特征来确定矿物的成因。③地球化学法:是指研究地壳中化学元素在各种地质作用过程中聚集的条件:如温度、压力、酸碱度等地球化学因素,以阐明矿物形成的物理化学环境、成矿物质的来源及成矿熔体或溶液的成因,从而确定矿物的成因。④物理化学法:是指研究形成矿物的物理化学的条件,以阐明矿物的成因。
