    Through graphical investigation of Soviet coal and Chinese coal, the follow-ing important conclusions are obtained. (1) The inadequacy of old coal classification methods is discussed and anentirely new method of coal classification with volatile matter on combustiblebasis as abssicca and the coal characteristic coefficient β=2.35((H~P-0.126O~P+0.04N~P)/(C~P+0.375S_?~Pas ordinate is proposed, The graphical charts show perfectly satisfactory withthe different kinds of coal located in perfectly distinct areas of classification.Thus the detailed classification which the old methods fail to give out, is perfectlypossible with the new method. (2) The ultimate composition of coal on combustible basis, like C~2, 0~2, H~2,N~2 and the analytical moisture, W~a and their variation with the volatile matteron combustible basis and with each other is graphically investigated and it isfound that their variation with each other proceeded with distinct regularitywith the exception of sulphur and ash, so that their composition percentage canbe approximatety estimated with rough accuracy through these graphs and theclose check of analytical results of ultimate composition can be carried outthrough the use of these graphs. (3) a general relationship in the proximate and ultimate composition of the pure coal substance on combustible basis for typical Chinese coals can bederived with the following straight line formula for the average percentage of car-ben on combustible basis in terms of the volatile matter on combustible basisin the region of bituminous coal: C~2=93.3-(V~2/4.55) during (8gas coal and steaming bituminous: Q_б~2=9860-((100-C~2)/0.0116) during C~2-78-88%. (5) The volume of theoretical air V_o~(мцн), dry combustion products F_(c.2.)~(мцн) andwet combustion products V_2~(мцн) in m~3/kg can be expressed as straight line for-mulas in terms of Q_H~P for the Chinese coals: V_o~(мцн)=(1.075Q_H~P)/1000 V_(c.2.)~(мцн)=((1.075Q_H~P)/1000)-0.2 V_2~(мцн)=((0.955Q_H~P)/1000)+1.10 For Soviet coals, straight line formulas are also derived as shown on thegraph. (6) This paper will find practical use in the fuel industry and power indus-try in operation and design work of power plants. The monographs for the coalcombustion calculations will be shown in another paper for the practical use forpower plant operation, because of too many graphs in one paper. Owing to the fact that the only data available for the ultimate analysis ofChinese coal is from the Northeast region and North China region, the degreeof accuracy of these graphs for Chinese coal is limited by the available data,although the comparison with the graphs for Soviet coals show a perfect simi-larity so that it can be concluded these graphs can be used for the Chinesecoals in other regions. Critical opinions are welcomed by the author to improve this paper.

    A knowledge of petroleum evolution is of critical significance in oil prospecting.First of all, the upper and lower limits of petroleum evolution are of prime importance in the evaluation of an oil-gas bearing area, because the nature and scale of oil-gas are controlled by the type and maturity of kerogen in sedimentary rocks For example, Tertiary oil-bearing basin's in eastern China (including the offshore continental shelf) is in the stage of oil-gas formation and an upper limit of petroleum...

    A knowledge of petroleum evolution is of critical significance in oil prospecting.First of all, the upper and lower limits of petroleum evolution are of prime importance in the evaluation of an oil-gas bearing area, because the nature and scale of oil-gas are controlled by the type and maturity of kerogen in sedimentary rocks For example, Tertiary oil-bearing basin's in eastern China (including the offshore continental shelf) is in the stage of oil-gas formation and an upper limit of petroleum evolution can be recognized. The major control of oil-gas nature for this region is the great abundance of terrestrial organic materials and its lower muturity. The marine carbonate strata in eastern China are older in age, and in the stage of oil-gas muturity with a lower limit of evolution. On the basis of the evolution model preliminarily established with respect to a certain region, the lower limit of oil and gas in carbonate district is lower than that of mudstone oil-bearing basins reported from other places in the world, with its petroleum lower limit corresponding to the stage of coke-lean coal or that of pynobitumen. For a correct evaluation, prospecting map in terms of petroleum evolution should be prepared in accordance with the model suitable for that region together with various organic geochemical index.A veiwpoint of petroleum formation, evolution and extinction will provide a deeper insight into the origin of oil and gas.The stages of petroleum evolution must likewise be taken into account if geochemical indexes for oil-generating rocks are to be applied correctly. For instance, OEP and clay minerals of mixed layers can only be taken as oil-generating index in the case of low muturity stage. Application of organic indexes of bitumen A/Corganie is difficult to recognize oil-generating rocks because of the ranity of bitumen A at the starting and ending stages during petroleum evolution. The bulk of organic materials in carbonate rocks are highly possible to be lost during diagenesis. From the consideration of petroleum evolution, during which stage it is lost may exert an influence on the evaluation of carbonate oil-generating rocks. Therefore, the study of sedimentary facies and diagenetic facies is also necessary.

    The petroleum industry of China has been developing at high speed on the basis of self-reliance and the situation is excellent. The abundant resources of continental oil and gas originated from continental oil-source rocks which are characterized by their wide distribution in space and full development in time, with four main oilgenerating periods, namely, the late Permian, late Triassic, early Cretaceous and Palaeogene. Some of the basic geologic characteristics of the continental source rocks are. (1) the presence of large sedimentary basins for the accumulation and development of continental deposits and source rock series, (2) the development of source rock series formed in many periods and many sequences within continental deposits, (3) the continental source rock series consisting of many types of source formations, (4) the existence of depressions inside the continental sedimentary basins serving as the centres for accumulation of oil and gas. The chief originating conditions of the continental oil-source rocks are: (1) the presence and development of ancient lake basins being the pre-requisite for the formation of oil-source rocks, (2) abundant source matter serving as the material basis for the formation of source rocks, (3) the favorable preservation and transformation of source material being the conditions requisite for the origin of source rocks. It has been proved through practice that not only petroleum but also large petroleum fields can be formed in continental sedimentary basins. China's developing petroleum industry will certainly score still greater victories under the guidance of Chairman Mao's revolutionary line.

    中国的石油工业在自力更生的基础上得到了高速度的发展,形势大好。中国丰富的陆相油气资源是由陆相生油岩形成的。这些生油岩在空间展布上具有广泛发育的特点,形成了晚二迭世、晚三迭世、早白垩世和早第三纪四个主要生油期。文中第一部分概述的陆相生油岩的若干基本地质特征是:一、大型沉积盆地是陆相沉积和生油岩系发育的广阔场所。二、陆相沉积发育有多时代和多层组的生油岩系。三、陆相生油岩系具有多种生油建造类型。四、陆相沉积盆地内的生油凹陷是油气聚集的主要供给体。第二部分论述了陆相生油岩的主要形成条件:一、古湖盆的存在和发育是生油岩系形成的首要前提。二、丰富的生油母质是生油岩形成的物质基础。三、生油母质的良好的保存和转化是生油岩形成的必要条件。实践证明,陆相沉积盆地中不仅能生成石油,而且能形成大型油气田。正在发展中的我国石油地质事业,在毛主席的革命路线指引下,必将取得更大的胜利。
