The Cedars ultramafic block hosts alkaline springs (pH > 11) in which calcium carbonate forms upon uptake of atmospheric CO2 and at times via mixing with surface water. These processes lead to distinct morphologies “floes” forming the atmosphere-water interface, “snow” fine particles accumulating bottom pools terraced constructions travertine. Floe material is mainly composed aragonite needles ...

The Plio-Quaternary Ait Chaib basin occupies the northwestern part of Skoura Syncline, which is northern Middle Atlas Folded Zone. This intracontinental was formed probably in Pliocene after Tortono-Messinian regression sea. deposits are bound by fluvial conglomerates and continental carbonates. They consist barrage travertines; travertine limestones oncholitic silts sands upstream downstream d...

Las Loras UNESCO Global Geopark (UGGp) is geologically diverse, particularly in relation to water-derived features: springs, karst travertine buildings, waterfalls, caves. In this work, the interactions between geology, geomorphology, structures and hydrogeology are analyzed. As a result of study, first conceptual model hydrogeological functioning at UGGp presented. The most plausible hypothesi...

A fossil remain of porcupine, a large-sized rodent hitherto unknown in Portugal, was identified during the 2010-13 excavation Last Interglacial deposit Figueira Brava cave. The specimen is left hemimandible retaining PM/4 to M/2 series but lacking incisor and M/3. Based on analysis its morphological odontometric features, we assign Hystrix cristata (Linnaeus, 1758). Nowadays, H. found Africa as...

vartun geothermal region (vgr) is located in west central part of iran, 300 km in the southeast of tehran. vgr area is 277 km2and there are some geothermal surface manifestations such as warm springs and travertine deposits. there are three warm springs which their temperature varies from 35.3 to 43.1 °c. their ph is a little bit acidic and is about 6.1-6.2. based on geothermometery studies var...
