Purpose. The work studies Sinjar formation (upper Paleocene lower Eocene) within the Bazyan anticline in Sulaimaniyah region (northeastern Iraq). facies analysis is based on petrographic study of limestone deposits and essential to identify their nature. sediments that formed have a high content skeletal granules which include small amount red algae residues unicellular organisms-foraminifera. ...

The theory of coalbed methane distribution controlled by tectonism is a hot issue in the field geofluid-geotectonic interaction research. Taking geological structure scale range 1302 working face Guojiahe wellfield Yonglong mining area as background, this paper focuses on basic research problem influence control coal reservoir gas content and uses THM coupling model to analyze change characteri...

This work documents for the first time prehistoric, but morphologically pristine, Emad Deh rock avalanche of Zagros Mountains. The ca. 420 Mm 3 was initiated as a rockslide on dip slope affecting weak unit marls with interbedded limestones overlain by thick and competent limestone formation. is located northern limb growing Gavbast Anticline at edge inflating Dome, related to buried salt diapir...

Kinematic constraints on the Cenozoic deformation along northwestern edge of Tibetan Plateau remain limited. Combining surface geological data and seismic profiles, we document structural geometry kinematics large-scale east-west striking Hotan anticline, foothills Western Kunlun Range. Four new balanced cross-sections are constructed, temporal evolution is deciphered from exceptionally well-im...

Industrial production activities associated with salt mining, hydraulic fracturing, or geothermal exploitation can induce pore pressure and stress field changes, thus inducing seismic activity. Most of the events are not disastrous due to limited energy radiated. Here we report a Mw 5.8 damaging event that occurred in Changning, China on June 17, 2019, probably largest induced by industrial eve...

The aim of this study was to propose the workflow for integrated analysis 3D geostress and 1D geomechanics an exploration in a new gas field. This will allow problems associated with inaccuracy geomechanical be overcome region obvious anticline/syncline structures. well field mainly included prediction pore pressure calculation mud weight window safe drilling. In general, both method window, nu...

A combination of digital image processing and field works provides a vision into differentiating between the rock units, in addition to contacts among them. Landsat 9 was used plot detailed geological map study area, located Al-Teeb city at Bajalia anticline, Missan Governorate, Southeast Iraq. The included geometric correction, enhancement, classification, use false-color composite technology ...

In south China the Lushan massif forms a Jurassic through Early Triassic [e.g., Mattauer et al., 1985, topographic high of the South China Block south of the 1991; Okay et al., 1993; Hacker et al., 1996; Gilder et al., Qinling-Dabie belt. The Lushan massif consists of two main 1999]. The noah directed continental subduction of south lithotectonic units separated by a major tectonic ontact: a Ch...
