The Chazy, Black River and Trenton Groups are a well studied sequence of fossiliferous limestones, dolostones and sandstones in the Champlain Valley of New York, Vermont and southern Quebec. These rocks record shallow water cyclic sedimentation in the foreland basin of Laurentia prior to and during the initial stages of the Taconic Orogeny. This field trip reviews the stratigraphy of these unit...
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 ...
the sorkh shale formation (lower triassic) crops out in parts of tabas block. this formation is composed of limestone, dolomite, sandstone, shale and gypsum. its lower contact with the permian rocks and its upper contact with the shotori formation is marked by distinct erosional unconformity. to determine the depositional environments of the sorkh shale formation, stratigraphic sections of goda...
This study integrates the results of numerical modeling analyses based on outcrop studies and structural kinematic restorations to evaluate mechanics thrust fault initiation development in mechanically layered sedimentary rocks. A field-based reconstruction a mesoscopic at Ketobe Knob central Utah provides evidence ramp nucleation competent units, propagation upward downward into weaker units b...
