Abstract
Karst topography is related to specialized climatic and lithographic criteria. Through an understanding of these basic processes an interpretative analysis of geochronologic dating can develop into an informative sequence. Chemical formula of karst, which I have first outlined, is essential to the question of location of such topography. The next logical step is defining those forms of karst which are found in temperate climatic areas. These can be applied to give relative dates of development. Special attention was applied to subterranean karst since these features tend to prevail longer than contemporary surface structures. Indirect methods for relative dates were also included to show they can be used in conjunction with the other principles. Finally, two practical examples, using these techniques, are shown. The central Kentucky and southern Indiana karst regions were studied in order to place relative dates on the formation of the cave systems. This accumulation of the various methods based upon the knowledge of karst formation will show the state of karst studies in today's text. By using these systems, a resolution of the question of ancient karst time tables can be pursued.
