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...

The infrastructure project has many lies on the mudrock foundation. Some reports in Hambalang, West Java, Indonesia, state engineering problem related to landslides and foundation failure due material's existence. originated from Jatiluhur Formation. is also present slope stability, such as surface erosion landslide slopes. Landslide material easily broken into smaller fragments. This research ...

Nineteen ichnotaxa, together with algal and invertebrate remains, various pseudo-traces sedimentary structures are described from the Torneträsk Formation exposed near Lake Torneträsk, Lapland, Sweden, representing a marked increase in diversity of biotic traces recorded this unit. The “lower siltstone” interval contains mostly simple pascichnia, fodinichnia domichnia burrows trails low-energy ...

The petrographic and geochemical analysis of the greywacke horizon late Neoproterozoic Hazara Formation from Mountains has been investigated to determine provenance, tectonic settings weathering history sediments. Late is a thick sedimentary sequence comprising greywacke, shale, argillites, siltstone, limestone. greywackes are characterized by fine medium-grained, moderately sorted sub-angular ...

Sistem penambangan batubara di Tambang Banko Pit 1 Utara adalah strip mining dengan sistem shovel-dump truck. Jenis material terdiri dari top soil, claystone, siltstone strength 0,2 – 3 Mpa dan sebagian perlu diledakkan. Untuk menunjang kinerja excavator dilakukan pemberaian overburden terlebih dahulu menggunakan ripper Komatsu D375A-5. Berdasarkan nilai kuat tekan (strength) material, spesifik...

CO 2 + O in situ leaching has been extensively applied uranium recovery sandstone-type deposits of China. The geochemical processes impact and constrain the reaction solution migration; thus, it is necessary to study –water–rock process its influence on physical properties uranium-bearing reservoirs. In this work, a simulation experiment was carried out, mineralogical multiscale pore characteri...

Deepwater lobes constitute a significant volume of submarine fans and are primarily believed to exhibit simple sheet geometry. However, recent studies interpret the geometries these deep-marine as distinct with respect complexity facies their distribution. Hence, conceptual model sediments is essential discuss associated fan lobe architecture. The present study highlights heterogeneity distribu...
