【摘要】 <正>分类是深入认识事物极为有效的途径,它使自然界那些纷繁杂乱的事物群得以系统化。分类的实质就是按照某一或某些特定的标志,将所研究的对象分为若干个有意义的组,组与组间在某些特性上具有明显的差异,而在同一组内则具有一定程度的相似性。分类不仅能使事物系统化,它在学术思想的交流和深入的研究工作中也是极有益处,甚至是不可缺少的。然而,任何分类系统都有其特定的目的和作用,这与试图解决的问题的性质相联系,问题的更多还原

【Abstract】 Depositional continuity of carbonate rocks, as a reflector of stability of their depositional environment, strongly affects karst development and thus karst morphology, and hydrogeological and engineering geological conditions. It might be taken as one of the indexes for classification of carbonate stratum types. In this paper, a classification, shown in the following table, is suggested according to the lithologic character and depositional continuity ( continuous depositional thickness ) of carbonate rock. When two or more types occur in one stratigraphic unit, it can be considered as a composite type. Besides, a BASIC program is given for stratigraphic analysis and determination of carbonate stratum types.更多还原
