摘要 

由数十个相对集中又彼此隔离的小型盆地组成的内蒙古二连盆地群,由于绝大多数盆地完全掩盖于新生界之下,地质调查只能靠很少钻孔,遇到很大困难.文章介绍了利用物探资料识别盆地、圈定盆地、计算盆地基底埋深、研究基底构造的方法和遇到的复杂情况.由于并非所有盆地都含煤,而不同的含煤盆地的赋煤构造部位又往往不同,因此,评价盆地的含煤性、确定赋煤部位就成为煤田远景调查工作中最棘手的技术难题.文章除介绍了常规的通过利用物探资料分析沉积环境,进而评价盆地含煤性的方法外,着重介绍了一种新的利用物探资料进行沉积环境分析的方法——垂向分析方法的产生过程以及利用这种新方法取得成功的实例.

Abstract

The Erlian basin group comprises tens of relatively concentrated yetseparated small basins. As most of these basins are completely covered by agreat thickness of Cenozoic sediments, geological survey has to depend only ona small number of drill holes and therefore meets with a great deal of difficul-ties. The present paper presents some techniques for recognizing and delineatingthe basins, for calculating the buried depth of the basins as well as for study-ing basement structures by using geophysical prospecting data, with a descrip-tion given concerning the complex situation met in the work. As only partsof the basins contain coal, and different coal-bearing basins frequently havediverse coal-bearing structural positions, the assessment of coal potential of thebasins and the determination of coal-bearing horizons make up the mostdifficult technical probroms in coal prospecting. Besides making a brief accountof the traditional technique for analysing sedimentary environment and thenevaluating coal potential of the basins by utilizing geophysical prospecting data,this paper deals relatively in detail with a new method for analysis of sedimen-tary environment by employing geophysical prospecting data-technique ofvertical analysis, describing the process of its emergence and development andgiving some practical examples showing its effectiveness.
