A multidisciplinary investigation was carried out in a karstic depression housing development under construction Madrid to assess its stability. It found that it is small basin within larger as result of subsidence accumulated during the Quaternary. Subsidence has built up progressively Miocene clay cap and bedrock due underlying dissolution gypsum rich intercalations. The preferential circulat...

This paper presents new results of a detailed structural analysis the bedrock Vistula source area within Silesian Beskids (Outer Western Carpathians, S Poland). The study is composed Upper Cretaceous flysch series Godula Beds and Lower Istebna Beds. located on southern limb Szczyrk Anticline Beskid Block. research based cartographic field work remote sensing digital elevation model from LiDAR d...

On the mid-Norwegian margin, extensive rifting and subsequent deposition of thick Cretaceous Cenozoic sediments have buried traditional Upper Jurassic organic-rich shales too deep. Consequently, these are overmature spent in deep basins on margin. The absence well-control, variable seismic quality particularly, great burial depth, makes it difficult to identify alternative Lower units. By combi...

As a preliminary phase in the conservation and sustainable management of karst system Fuentetoba, Soria, Spain, an interdisciplinary study was carried out to determine its hydrogeological evolution. The history this aquifer began during late Miocene, where discharges were driven by paleo-emergences moor, associated conduits developed under phreatic (or vadose) conditions—for example, upper syng...

Proper water resources management requires recognizing and evaluating the factors that affect quantity quality of resources. The Ilam-Sarvak (Upper Cretaceous) Asmari (Oligocene to Miocene) limestone- dolomite formations in Zagros structural belt have formed a promising karst groundwater horizon. In present study, hydraulic relationship between structures Izeh territory northeast Khuzestan prov...

Abstract The southern margin of the Sichuan Basin is characterized by strong structural deformation, complex fault structure styles and scales, multistaged geological evolution stages, which together have created various shale gas preservation conditions. Taking Jianwu (JW)–Luochang (LC)–Shuanglong (SL) synclines as an example, development characteristics Longmaxi Formation were studied based o...

abstract: in this research, the relationship between geomorphologic factors with underground water resources in zahab plain (in west of kermanshah) has been analyzed using by analyzing-deducing and weighting methods. first, by using of pizometeric and exploratory well data, variation of water table in zahab plain has been comparative analysis with geomorphic unites and then, the zahab watershed...

S U M M A R Y The Upper Carboniferous-Lower Triassic Pyongan Supergroup is exposed in an E-W trending syncline comprising the Samcheok Coalfield in eastern South Korea; it borders the southern margin of a NE-SW trending (Okcheon) zone of Upper Jurassic-Lower Cretaceous deformation (Daebo Orogeny). Although a Recent field overprint widely recorded in Korean rocks is represented here, an ancient ...

Introduction: The chemical and physical processes by which spherules form during the condensation of impact-produced rock vapor clouds are poorly understood. Although efforts have been made to model the processes of spherule formation, there is presently a paucity of field data to constrain the resulting theoretical models. The present study examines the vertical compositional variability in a ...

The Hama-Koussou Basin is one of the offset structures eastern end Benue Trough in Northern Cameroon. This sedimentary basin an asymmetrical syncline whose axis strongly shifted towards East, filled predominantly with Cretaceous deposits, has experienced at least three (3) phases sedimentation during its geological history: two (2) fluvial top and second bottom consisting conglomerate, micro-co...
