ABSTRACT The Wajid Group is a Palaeozoic siliciclastic succession of southern Saudi Arabia. In the outcrop belt it ca. 500 m thick, whereas in subsurface, thickness increases to more than 4,500 m. sediments have great reservoir potential for hydrocarbons and groundwater. Although they represent one most important aquifers Arabian Peninsula, neither their sedimentologic, lithostratigraphic, nor characteristics are satisfactorily known. this study, detailed description lithology sedimentology...
Abstract Saudi Arabia is one of the few places in Gondwana where deposits two Palaeozoic glaciations are well preserved. They were formed under similar conditions a tectonically stable shelf setting. We studied sedimentary facies and architectural geometries Upper Ordovician Permo-Carboniferous glaciogenic Wajid Sandstone developed genetic model for both units. Common features glacial episodes (a) incision (tunnel?) valleys, (b) subsequent valley fill by proglacial front an oscillating,...
Abstract The stratigraphical record of the Argentine Precordillera from Early Cambrian to Late Devonian times reveals its plate-tectonic history incipient rifting and evolution a marginal platform separation Laurentia, drift in higher latitudes amalgamation with Gondwana. This pre-Carboniferous succession can be subdivided into four supersequences bounded by major unconformities their main features are discussed respect implications. basal two which include carbonate deposits 13 third-order...
ABSTRACT Carbonate ramps are special carbonate depositional settings, characterized by very gentle slopes extending from the coast to offshore without a marked break in slope. In Cantabrian Mountains of Northern Spain ramp developed during Early Devonian (Abelgas Formation). An inner tidal-flat complex bounded small oolite shoals (Dolomite Member) on southern edge Block and south west passed into mid ramp, where shallow-water storm-influenced limestones shales (Lumajo nodular (Wavy Limestone...
Abundant and regionally unique dolostone lithoclast breccias occur throughout the shallow‐marine, Lower to Middle Ordovician Pogonip Group in Nopah Range adjacent ranges eastern California southern Nevada. Breccia bodies display sharply cross‐cutting relationships with host bedrock stratigraphy. They also show stratigraphic variability size, shape clast composition, but similarity breccia matrix composition framework texture fabric. These characteristics are consistent a palaeokarst origin....
Abstract The Argentine Precordillera (Cuyania terrane) and the Marathon/Solitario basin (west Texas), both underpinned by Grenvillian Laurentian basement, evolved together during Early Cambrian to Mid-Ordovician times. Ages, Pb-isotope geochemical data for Precordilleran west-central Texas basement (including Llano uplift) are strikingly similar. Carbonate platform sequences developed on sides (e.g., El Paso Chica de Zonda) of outer-shelf slope hosted homologous reef organisms which were...
Nitrate (NO3−) represents one of the major groundwater constituents with increasing distribution and concentration in Kingdom Saudi Arabia. This study aimed to determine potential sources nitrate Early Late Cretaceous Wasia aquifer system at Al Kharj area (Central Arabia) by an integrative approach using geochemistry, isotopes (15N–NO3 18O–NO3), tritium (3H) measurements. The lowest saline samples (TDS = 1400–2000 mg/L) from peripheral zone were representative for pristine concentrations...
