The compositional record of the AND-2A drillcore is examined using petrological, sedimentological, volcanological and geochemical analysis of clasts, sediments and pore waters. Preliminary investigations of basement clasts (granitoids and metasediments) indicate both local and distal sources corresponding to variable ice-volume and ice-flow directions. Low abundance of sedimentary clasts (e.g.,...

Shales are defined as fine-grained terrigenous sediments and rocks that contain 50% or more of terrigenous, and generally argillaceous, clastic components less than 0.062 mm in size. In the shales, clay-size components often dominate their rock properties, such as density, plasticity, parting, compatibility and swelling. Generally the size boundary between clay and silt is 4μm, but most clay mi...

Compressions and impressions of an isoetalean lycopsid, comprising lower portions of stems, lobed bases, attached rootlets, and rounded rootlet scars, discovered in Late Devonian (Famennian) rocks of Clinton County, north-central Pennsylvania, Appalachian Basin, USA, are here described as Otzinachsonia beerboweri, gen. et sp. nov. These specimens demonstrate unequivocally the existence of the i...

New fossil discoveries are reported from the Grammajukku Formation at Luobákte south of Lake Torneträsk in northern Swedish Lapland, including a fauna Small Shelly Fossils (SSF) limestone bed uppermost part formation and new occurrences brachiopods trilobites siltstones lower formation. The moderately diverse SSF is first its kind Caledonides includes record tommotiid Lapworthella schodackensis...

The Nahr Umr Formation is considered one of the main reservoirs produced in southern Iraq. It important siliciclastic deposits Cretaceous sequence Iraq oilfields. Zubair oil fields ZB-190 and ZB-047 were chosen to study areas. This depends on available core cutting samples determine facies analysis, depositional environments, petrographic characteristics diagenesis processes. Based description ...

The work pursued basic objectives: to study the structure of sedimentary strata, identify sediment units corresponding specific sedimentation stages late Holocene and evaluate factors that influenced their formation in Vistula Lagoon. For achievement goals, well-known methods were used. thickness silt deposits was measured by a hand drill. grain size analysis bottom sediments determined mass co...

Geophysical surveys are a noninvasive reliable tool to improve geological models without requiring extensive in situ borehole campaigns. The usage of seismic refraction tomography (SRT), electrical resistivity (ERT) and data for calibrating is very appropriate define landslide body geometries; however, it still only used occasionally. We present here the case Spanish Pyrenees slow-moving landsl...

The Triassic Jiucaiyuan Formation is a vital oil and gas exploration target in the eastern part of Junggar Basin. In this work, cores, thin sections, particle sizes, conventional physical properties were analyzed order to understand sedimentary characteristics depositional model Beisantai Uplift clarify factors controlling reservoir development. results demonstrate that can be divided into seve...

The Eocene to Lower Oligocene deposits of the Penyu and Malay basins are formed by fluvial-lacustrine with marine influence in latter. sequence consists mainly siltstone, several intercalations fine-grained sand volcanic tuff. Based on well data, Mid-Upper sediments exist Basin deeper parts half grabens sub-basins. Hence, this implies age basin initiation at Mid-Eocene, rather than as tradition...

The study area is an oil and gas field that has a low resistivity reservoir zone in the Talang AkarFormation, South Sumatera Basin. composed of siltstone sandstone was depositedin shallow to transitional marine environment. aim this identify determine potential oflow reservoirs formation. data used include well log, mud core data(porosity, permeability, petrography), formation water analysis, b...
