Thick carbonate rocks were developed in the depression of the Tarim craton during the Cambrian-Middle Ordovician periods. The compressional tectonic movement during the Middle Caledonian-Hercynian created the paleouplifts, which became the base for the paleokarst in the Ordovician carbonate rocks. Based on the large quantity of seismic, drilling, and geological outcrop data, this study analyzed...

Abstract Paleokarst breccias are a common feature of sedimentary rift basins. The Billefjorden Trough in the High Arctic archipelago Svalbard is an example such rift. Here Carboniferous stratigraphy exhibits intervals paleokarst formed by gypsum dissolution. In this study we integrate digital outcrop models (DOMs) with 2D ground penetrating radar (GPR) survey to extrapolate external irregular g...

Algeria displays various karst landscapes due to its diversity in lithology, relief, age and climate. On 16th June 1988, the northwest of Algeria, a 60 m wide sudden collapse occurred Chelif Basin about 1 km north marginal carbonate platform. Despite this large event visible dissolutions platform, region has not been classified among areas yet. Our study focuses on Messinian carbonates that for...
