Based on waveform data from a profile of aftershocks following the north-south trace of the 28 June 1992 Landers rupture across the Mojave desert, we construct a new velocity model for the Mojave region that features a thin, slow crust. Using this model, we obtain source parameters, including depth and duration, for each of the aftershocks in the profile and, in addition, any significant (M > 3...

The process wherein groundwater flowing from mountain bedrock into lowland and adjacent alluvial aquifers, known as mountain-block recharge (MBR), is found across various climatic geological settings. An understanding of the potential flow paths in block systems necessary for comprehending MBR spatial distribution. However, poorly characterized hydraulic properties, especially a lack direct mea...

Image logs of 13 wells in the Rag Sefid Anticline show two systems of fractures developed under two deformation phase in the Dezful Embayment. This deformation phases are folding resulted from Zagros NE contraction and reactivation of the basement fault rotated the fold axial trace within the Hendijan-Izeh fault zone. Folding phase comprises four sets of fractures, which include axial and cross...

This study aims to develop a system that improves operational efficiency by centrally managing the information obtained at each stage of design, construction, and maintenance mountain tunnels. In this study, items required for tunnels are examined in reference building modeling (BIM) has been developed field architecture. The basic includes topography, geology, support design planning stage; ob...

the rijab area with189 square kilometers is located in northwest of zagros and north of sarpol zahab city. its main skeleton is made of hard and resistive layers of shahbazan dolomite and asmari lime, that its eastern part is pressed as an anticlinorium form but its western part as a syncline form. as a result of kerend fault practice most of the tectonically activities are seen in middle parts...

Mountain glaciers respond directly to changes in precipitation and temperature, thus their margin extent is a high-sensitivity climate proxy. Here, we present a robust (10)Be chronology for the glacier maximum areal extent of central Spain paleoglaciers dated at 26.1 ± 1.3 ka BP. These glaciers reached their maximum extent several thousand years earlier than those from central Europe due to the...

the noorabad-kermanshah ophiolite is part of eastern mediterranean-zagros-oman tethyan ophiolites, that this area is located in south-southwest of the main zagros thrust fault. this ophiolite consists of peridotites, serpentinites and pegmatite gabbros as mantle sequence whereas crustal sequences are composed of locally layered gabbros, isotropic gabbros, sheeted dike complex, basaltic to andes...
