This paper focuses on the Frasnian reefal development in eastern border of Dinant Synclinorium. Classical sections from Durbuy–Bomal area were reevaluated for lithostratigraphy, microfacies, magnetic susceptibility (MS) and diagenesis. As regards middle succession, studied is located a transitional zone between Pont de la Folle/Philippeville Formations Moulin Liénaux/Grand Breux Formations. suc...
The Sachun Formation (Paleocene-Lower Eocene) is mainly composed of carbonates and evaporates that were deposited in shallow-marine evaporitic mudflat environments. The Sachun Formation in the study area has been divided into three units including: lower evaporate; middle bioclastic limestone and upper evaporate. It is mainly composed of diagenetic gypsum, which originated from dehydration of a...
The hosted-rocks of the Pb-Zn ore deposits in two mines of Karavangah and Dehno (north of Kuhbanan) contain carbonate rocks of the Shotori Formation (Middle Triassic).The identified carbonate facies consists of limestone and dolomite, but ore bodies mainly occurred in dolomite facies. Petrographic studies show that the dolomites can be divided into four classes including fine crystalline, mediu...
The vast majority of carbonate minerals in modern marine sediments are biogenic, derived from the skeletal remains organisms living ocean. However, can also precipitate abiotically within sediments, and this mineral precipitation has been suggested as a third major, isotopically distinct, sink global carbon cycle, particularly important earlier Earth history. Here we present compilation pore fl...
