Abstract
The correlation between surface and subsurface karst development was explored by comparing the directionality and spatial distribution of karstic depressions around twenty-two select caves in the eogenetic karst of Florida. Orientations of cave passages and major axes of depressions around cave centrelines imply varying degrees of correlation between them. Spatial distribution of karstic depressions was studied by standard deviational ellipses of sinkhole centroids and nearest neighbour orientations around caves using spatial statistics tools of ArcGIS. An overall analysis of the data shows close connections between some caves and the surrounding sinkholes in terms of their orientation and spatial distribution, suggesting the importance of fracture systems in the development of karst.
期刊介绍：
Karst areas occupy 10-20 % of ice-free land. Dissolution of rock by natural waters has given rise to specific landscape and underground. Karst surface features and caves have attracted man''s curiosity since the dawn of humanity and have been a focus to scientific studies since more than half of millennia.
Acta Carsologica publishes original research papers and reviews, letters, essays and reports covering topics related to specific of karst areas. These comprise, but are not limited to karst geology, hydrology, and geomorphology, speleology, hydrogeology, biospeleology and history of karst science.
