On the basis of an international collaboration agreement between the Armenian Speleological Center and the Hyblean Center of Speleo-Hydrogeological Research of Ragusa, Italy, in the years 2016–2017–2018, three research campaigns were carried out on the karst and volcanic morphologies present in some areas of the Republic of Armenia. In 2016, the af...

Widespread distribution of chert nodules in the Chihsian Formation, South China, provides insightful clues for Middle Permian paleoceanography, while the occurrence of these cherts is enigmatic. In this study, micro-area and in situ geochemical analyses were conducted on cherts and carbonates from the eastern Pingdingshan outcrop, aiming to deciphe...

The foraminiferal contents of the Paleocene-Eocene successions were examined in two sections; at the southern and northern flanks of Chenareh anticline, Lorestan Zone. The Paleocene-Eocene in northern flank was subdivided into three formations from older to younger: Taleh Zang, Kashkan, and Shahbazan formations. During this time, sedimentation of t...

The present study investigates the processes responsible for Middle Eocene dolomite occurrences in Kachchh Basin in the western Indian Continental Shelf. Three types of dolomites are identified. They exhibit euhedral to subhedral crystal boundaries and a core of calcite or amorphous organic matter. Non-stoichiometric dolomite is the major component...

The formation environment of continental evaporite—particularly the sedimentary environment closely related to continental evaporite deposits—has received significant research attention for several years. From this perspective, an intermountain basin exists in the inland area of Northwest China, known as the Kumishi basin. The elevation of this bas...

Dolomitization is a hot issue due to the fact that dolomitized successions host hydrocarbon reservoirs. Hence understanding the dolomitization process is very vital to anticipate the probable presence of dolomite bodies in the subsurface. Multi-phase dolomitization process can be best understood by investigating partially dolomitized carbonate sequ...

The Gattar and Bireno carbonate platforms developed in Central Tunisia during early and middle Turonian, respectively. Most previous geological works consider these carbonate platforms as rimmed shelves, that developed up on a substratum arranged into a series of blocks bounded by major E–W faults. The present work aims through field observation an...

The United Nations Educational, Scientific, and Cultural Organization (UNESCO) has recognized more than 350 karst areas of global importance through various designations (Biosphere Reserve, World Heritage Sites, Ramsar Sites, and Global Geoparks) with at least one UNESCO protected area with karst in 86 countries (Gunn 2020). In August 2020, Western...

Variability in landscapes drives patterns in biological communities and is often used to understand biological systems. Rarely, however, have biological systems been used to understand landscape evolution. Here, we review the geomorphic history of cave development in the southern Sierra Nevada Mountains and look at the detail that modern biological...

Calcitized Ordovician dolostones in the Yichuan-Huanglong area of the Ordos Basin (China) are discussed and evaluated by utilizing petrographic, mineralogical and geochemical data. Symbiotic dedolomites with red and white colors are separated and studied. The new data demonstrate that the red dedolomites (Dd1) occurred as the result of the migratio...
