沉积作用之旋回性影响到沉积矿产在垂直剖面上之分布,这是显而易见的。φ.φ.巴依—巴拉耶夫曾指出煤系剖面中部为最有利的的积煤条件。本文证明,陕北延长群及侏罗系的旋回结构和控制油层的出现,这可能与有机物质堆积及初次运移条件有关。这里引用的实际材料及分析数据,为作者及石油系陕北科研分队同学于1960年工作中所获;文中的基本论点也为师生共同的劳动成果。不当之处,自不在少数,希同志们指正。
The cyclonic nature of sedimentation affects the distribution of sedimentary minerals in the vertical profile, as is evident. φ.φ. Baey-Balayev pointed out that the middle part of the coal measure is the most favorable coal accumulation condition. This paper proves that the extension of the Yanchang Group and Jurassic in Northern Shaanxi and the occurrence of controlled reservoirs may be related to the accumulation and initial migration of organic matter. The actual materials and analytical data quoted here are obtained from the author and students from the Northern Shaanxi Scientific Research Team of the Department of Petroleum in 1960; the basic argument in the article is also the common labor result of teachers and students. Inappropriate place, since not few, Greek comrades correct me.
