Introduction The vertical and horizontal movements of the Earth crust have caused extensive changes in surface phenomena, in the active tectonic regions. In order to measure some of these changes, morphometry analyses have been used to evaluation of the amount of tectonic activity. These analyses are useful tools for analyzing existing feature at the ground level and provide a proper understan...

Pore and its structural characteristics are key parameters affecting shale gas reservoir development. Accurate quantitative characterization of pore is great significance for evaluating state. In this study, 15 shallow marine samples were collected in Well Y108. X-ray diffraction results indicate that brittle minerals the most common components shale. paper, various types classified characteriz...

Abstract The cosmopolitan genus Gondwanaspis is one of two post-Taghanic (late Givetian to Frasnian) odontopleurid genera and the only Odontopleurida surviving Lower Kellwasser Event, finally disappearing at Upper Event. Although it known from Frasnian Australia, Germany, France, Morocco, Russia, findings are comparatively rare. Here we present eisbornensis n. sp. probable lower Beul section ne...

among all the geophysical techniques, the magnetotelluric method has improved considerably in recent years and is widely being used in hydrocarbon exploration especially in regions where reflection seismic has difficulties. areas which are covered with high velocity rocks in the near surface are most popular cases. a huge high resolution magnetotelluric investigation was conducted in the sehqan...
