Collapse dolines and deflector faults as indicators of karst flow corridors
International Journal of Speleology, 2002 The paper concerns collapse dolines, which appear to be one of the best-defined surface karst phenomena. Despite this appearance, one may find quite different views in the literature, and some of the aspects of their morphogenesis have been overlooked completely.

Gypsum dissolution geohazards at Ripon, North Yorkshire, UK [PDF]
, 2007 This guide is for a one-day field excursion to examine gypsum dissolution geohazards at Ripon in North Yorkshire. Gypsum is a highly soluble rock and under suitable groundwater flow conditions it can dissolve forming caves and karstic features including ...

The purpose of this activity is to explore the way water moves through a porous, soluble substance and to observe the development of pits and channels as the substance dissolves in water. Students learn what karst is and how it is formed.

Carsologica SinicaKarst ground collapse is one of the most common geological hazards in karst areas. It is characterized by concealment, sudden occurrence and inhomogeneity, along with various other complex features.

A remote sensing evaluation of potential for sinkhole occurrence [PDF]
The relationship between lowering of the water table and sinkhole development in Pierson and in Hillsborough County, Florida was investigated. The locations of recently developed (1973) collapses were examined with respect to lineaments or fracture ...

Experiment on monitoring and early warning of karst collapses based on acoustic emission technology
Carsologica SinicaThe karst collapse is a dynamic geological process in which the damage of soil mass and development of cavity ultimately result in the instability of the overburden layer.

Epigene and Hypogene Karst Manifestations of the Castile Formation: Eddy County, New Mexico and Culberson County, Texas, USA [PDF]
, 2008 Permian evaporites of the Castile Formation crop out over ~1,800 km2 in the western Delaware Basin (Eddy County, New Mexico and Culberson County, Texas, USA) with abundant and diverse karst manifestations. Epigene karst occurs as well-developed karren on

MEVTV Workshop on Tectonic Features on Mars [PDF]
The state of knowledge of tectonic features on Mars was determined and kinematic and mechanical models were assessed for their origin. Three sessions were held: wrinkle ridges and compressional structure; strike-slip faults; and extensional structures ...

Sinkhole genesis and evolution in Apulia, and their interrelations with the anthropogenic environment [PDF]
, 2004 Sinkhole development occurs in many areas of the world where soluble rocks crop out. Sinkholes are generally the surface expression of the presence of caves and other groundwater flow conduits in carbonate rocks, which are solutionally enlarged secondary
