A layer of shallow-water dolostone (“cap dolostone”) with idiosyncratic sedimentary structures was deposited across continental margins world-wide in the aftermath of the terminal Cryogenian snowball Earth. The dolostone has a global average thickness of 18.5 m and is interpreted stratigraphically in different ways in the current literature: as diachronous (top and bottom) and tracking glacioeu...

The current study is designed to analyze theslope stability of Haditha damwhich an earth-fill dam constructed on the Euphrates River in middle-west Iraq. Finite element modeling was used present combined seepage and post-earthquake slope earth dam. maximum water level a steady case considered evaluate seepage. - Three different levels (maximum, normal, minimum) were applied, nine equilibrium li...

this research intends to develop a method based on the artificial neural network (ann) to predict permanent earthquake-induced deformation of the earth dams and embankments. for this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. in order to predict earthquake-induced deformation o...

[1] Detailed mapping has revealed several stratigraphic components among lobate plains in the vicinity of Sekmet Mons volcano (44.5 N. lat., 240.5 long.), located on the northern lowland plains of Kawelu Planitia on Venus. Volcanic effusion events produced discrete lobate plains throughout the area. Superposition of flow margins between adjacent lobate plains components indicate that the effusi...

Impact cratering is a common geological process in the Solar System and most planetary bodies display geomorphologies strongly influenced by impacts (Lowman 1997). Fresh impact craters are normally characterized by a circular morphology (Melosh 1989). This surface expression is modified on Earth by active geological processes. The variation of terrestrial impact structure expressions suggests a...

Long length vacuum oscillations solution of the solar neutrino problem is discussed. We show that there is a strict correlation between a distortion of the neutrino energy spectrum and an amplitude of seasonal variations of the neutrino flux. The slope parameter which characterizes a distortion of the recoil electron energy spectrum in the Super-Kamiokande experiment and the seasonal asymmetry ...
