The Aptian Crato Formation is world renowned for its well-preserved fossils in microbially-induced laminated limestones, which are regarded as one of the main Cretaceous Konservat-Lagerstätte geological record. Detailed stratigraphic investigation and mapping up to 90-m-thick at eastern border Araripe Plateau allowed recognition a regionally persistent fossil-bearing muddy interval, herein defi...

Abstract The Cretaceous sediments in southwestern Nigeria are host to one of the largest bitumen deposits world. In current paper, an integrated study on sedimentology, palynology, and applied petroleum geochemistry Maastrichtian-Paleocene Araromi Formation was used determine depositional environments hydrocarbon potentials formation eastern Dahomey Basin. Four sedimentary lithofacies were iden...

Coal mining has caused groundwater pollution and loss. Using a mined area as water storage space for storing purifying mine is low-cost environmentally friendly method. In this study, static dynamic adsorption experiments on the ions in were carried out using roof rocks from Lingxin coal mine. The sample analysis results show that main chemical composition of mainly SiO2 Al2O3. chemistry type S...

The stimulation method of the marine natural gas hydrate (NGH) reservoir through hydraulic fracturing has been proposed to resolve problem low production capacity in conventional development pressure drawdown. Nevertheless, due strong plasticity and high argillaceous siltstone content NGH reservoir, small-particle-size proppant cannot form effective support for fractures after because serious e...

ABTRACTTo extract vanadium (V) ions from the ferruginous siltstone at Abu Zeneima in Southwestern Sinai, Egypt, a synthesized chelating N-phenyl acetyl-N-naphthyl hydroxyl amine (PANHA), was used. Complete characterization carried out successfully to elucidate structure using several techniques such as FT-IR,1H-NMR, 13C-NMR, GC-MS and TGA analysis performances. Improved experimental measurement...

Abstract Movement of soil and rock masses down the slope or known as landslide is a natural activity that can pose danger to humans. Generally, be influenced by slope, materials (rock/soil), rainfall. Morphologically, study area, which located in borders Tembalang Banyumanik Districts, Semarang City, hill quite steep. It has potential experience landslides. Landslide occurences at area do not a...

A thick sequence of Ediacaran (Vendian) deposits is exposed in the southwestern part Ukraine along valley Dniester River and its left tributaries. The stratigraphy lithology these have been studied some detail, but information on fossil record still very scarce. Kanilovka Group sedimentary has lowest level exploration. Tymkivia primitiva gen. nov. sp. described from Late shallow-water marine ro...

Detrital zircons in the matrix of an accretionary complex play important role providing evidence to reconstruct oceanic plate subduction and accretion processes. The Nadanhada (NAC) dominated by Yuejinshan, Raohe Tongjiang complexes provides significant geological better understand Paleo-Pacific subduction–accretion process. Most previous studies have focused on Yuejinshan complexes, while thos...

This study focuses on the thermal maturity of Permian deposits from Zagros Basin, Southwest Iran, employing both optical methods (Thermal Alteration Index, Palynomorph Darkness Vitrinite Reflectance, UV Fluorescence) and geochemical analyses organic matter (Rock Eval Pyrolysis MicroRaman spectroscopy) applied to Faraghan Formation along two investigated Darreh Yas Kuh e surface sections. Furthe...

Carbonate rocks of the Triassic deposits South Mangyshlak basin are investigated in this paper for their boundary values, which important interpretation field geophysical data as well perforation and blasting. Based on lithological composition, classified either terrigenous or carbonate reservoirs. reservoirs found Middle strata containing volcanogenic dolomite limestone rocks. A complex type r...
