The central Apennines are a fold-thrust belt currently affected by post-orogenic extensional seismicity. To constrain the influence that inherited thrust-related structures exert on present seismic behavior of belt, we provide high-resolution structural and hydraulic characterization one most external exposed thrust fault systems Apennines, Sibillini Mts. Thrust Front (STF). We integrate mappin...

abstract this survey accomplished for asessment and mechanism recognition of chenaran watershed landslide effective factors and its zonation based via lim model. primarily recognized effective factors, through studing and field survey and evaluated by landslide index method(lim) then based on their weight in model, landslide hazard zonation was done.then evaluated this model competence in zonat...

kopet-dagh basin is located in north and northeast of iran. khangiran formation is one of the most important formations of paleogene deposits. for study of khangiran formation bivalves, chehelkaman syncline section has been selected. this section located in west of sarakhs city, east of kopet-dagh basin. lithology of this formation in the sarakhs region composed of marl, marly limestone and sil...

Mashhad Plain affects by a series of active faults in the northern margin of the Binalud and the southern margin of the Kopet-Dagh mountain ranges. The activity of these faults forms the morphology of the stepped bedrock of the Plain. In addition, the faults’ activities in the Quaternary period are the main effective parameters in thickness and texture of aquifer deposits in Mashhad Plain. In t...

One of the challenges 3D geological modelling is spatial representation heterogeneous sedimentary rocks. The R’Mel coastal basin located in northwestern Morocco a very suitable area for rock formations. This part external Pre-Rif and composed rocks Miocene to Quaternary age (principally sand, marl, sandstone, silt, alluvia). Due impact climate change, any increase abstraction groundwater can ac...

The Sa’adi Formation is a part of the late Cretaceous period in Santonian-Campanian stage that represents potential hydrocarbon-bearing reservoir across many oilfields Mesopotamian Basin, South Iraq. was divided into two main parts as stratigraphy sequence. It consists chalky limestone with argillaceous upper and marly lower part. considered an important stratigraphic unit marked by petroleum s...

The microfacies analysis and porosity evolution of the Khurmala Formation (Paleocene-Early Eocene) were studied in Gomaspan Sheraswar sections High Folded Zone, northeastern Erbil City, Kurdistan Region (N-Iraq). Lithologically, section is about 23.5 m comprised thick to massive bedded brecciated grey dolomitic limestone lower middle parts interbedding medium beds yellow calcareous shale upper ...

the upper cretaceous carbonate sequence of ab-deraz formation is well exposed in the kopet- dagh basin. this formation comprises marly limestone and three chalky limestone units. chalky limestone of ab-deraz formation is mainly composed of calcareous dinoflagellate (pithonellid calcispher), cocolithofore and planktonic foraminifera. carbon and oxygen stable isotopes analysis of the third chalky...

tirgan formation with lower cretaceous age (barremian-aptian) in the kopet-dagh basin consists of carbonate and siliciclastic rocks (calcareous shale and sandstone) which conformably lay between siliciclastic rocks of shurijeh formation below, and marly sarcheshmeh formation at the top. in this study, tirgan formation in two stratigraphic sections of abgarm (77 m in thickness) and sirzar (46 m ...
