Chapter
This study introduces a new sequence stratigraphic framework for the Middle-Late Triassic Yanchang Formation based on the sedimentological analysis of a ~ 850-m-thick composed stratigraphic column constructed after the integration of 21 partial field sections and 17 high-resolution photomosaics showing overviews of the stratigraphy and stacking of...

Deltas constitute complex depositional systems formed when a land-derived gravity-flow (carrying water and sediments) discharges into a marine or lacustrine standing body of water. However, the complexity of deltaic sedimentary environments has been oversimplified by geoscientists over the years, considering just littoral deltas as the unique possi...

The Ordos Basin is one of the most important oil-bearing basin of China. During most of the Triassic, this basin accumulates extensive fluvial-lacustrine deposits forming a very thick succession assigned to the Yanchang Formation. One distinctive characteristic of the Yanchang Formation is the virtual absence of coarse-grained deposits (i.e. gravel...

Paleosols are very important paleoclimatic indicators, since they provide evidence not only about the existence of exposed (weathered) surfaces, but also about other important paleoclimatic parameters. During the Middle-Late Triassic, the Ordos Basin in China was a huge continental basin characterized by a permanent lacustrine body surrounded by d...

Tidal action is an important process that can eventually control the shape and distribution of clastic bodies in marine basins. The effect of tides can be locally very important in shallow marine settings, although tidal processes can be recognized also along turbidity canyons. In contrast with the marine counterpart, tidal action in large lacustri...

The Triassic Yanchang Formation in the Ordos Basin (People's Republic of China) contains one of the biggest and most famous oil-bearing lacustrine records of the world. These continental deposits were accumulated in a complete suite of lacustrine and related environments ranging from deep water to subaerial conditions. During decades, most studies...

During the Barremian, the Neuquen Basin experienced a permanent disconnection from the Pacific Ocean, resulting in the development of an extended underfilled lake system. Lacustrine deposits comprise a more than 1000 m-thick succession of clastic and minor evaporitic deposits assigned to the Rayoso Formation. This unit is internally composed of thr...

The conventional sedimentological model suggests that the accumulation of organic-rich fine-grained sedimentary rocks (<62.5 μm) is uniquely associated with fallout processes in low energy depositional environments. This contribution analyzes organic-rich mudstones belonging to the lower section of the Vaca Muerta Formation at central areas of the...

Marine sedimentation in the Neuquén Basin started in the Early Jurassic with the accumulation of a progradational clastic system: the Cuyo Group. This sedimentary cycle begins with offshore shales of the Los Molles Formation, transitionally overlaid by shelfal to littoral sandstones and conglomerates of the Lajas Formation. According to the current...

Cores recovered from PANG0001 and PANG0003 wells provide an exceptional record of the upper Paleozoic of the Ventania/Claromecó Basin. These wells are located at 90 km at the northeast of Sierra de la Ventana locality, reaching a depth of 958.30 and 901.66 meters, respectively. Two continuous sections of more than 700 m each were described. These c...

Hydrocarbons are contained on rock pore spaces. Porous sedimentary rock bodies have shapes, thickness, and continuity that depend mainly on active depositional processes during accumulation. In this context, the sedimentological model (or static model) represents an approximation to the reality of the oil field. An accurate model is necessary to re...

RESUMEN El rol de los flujos fluidos de fango en la acumulación de fangolitas bituminosas. Formación Vaca Muerta (Tithoniano temprano-Valanginiano temprano), Cuenca Neuquina, Argentina. Durante los últimos años, el avance de técnicas no convencionales de explotación de hidrocarburos puso especial interés en obtener una mejor comprensión de los proc...

The representation of core and outcrop data in on-scale sedimentary columns is a common practice in modern Geology. Either core or outcrop description involves the observation of a human and the related annotations. The traditional practice consist on sketching at the field or at core facilities and afterwards redrawing the chart at the lab. Conven...

Bioturbated heterolithic clastic reservoirs are often characterized by clean sandstones forming thin levels, small patches, and burrow infills. This scenario makes precise estimation of percentage of sandstone (net-to-gross) a very difficult task. At present, there are no tools available that allows a straightforward quantification of the sand cont...

Spectrometry applied to the study of Vaca Muerta Formation (Early Tithonian-Early Valanginian), Neuquén Basin. Reflectance spectrometry allows to determine different rock components by the analysis of electromagnetic waves. At present, this technique is widely used in mineral exploration since it allows a rapid and precise recognition of minerals c...

La Formación Vaca Muerta (Jurásico tardío-Cretácico temprano) constituye una unidad espesa de sedimentitas marinas ampliamente distribuidas en la Cuenca Neuquina. Se compone por materiales mixtos silicoclásticos-carbonáticos con elevado contenido orgánico, los cuales conforman una sucesión alternante de lutitas, margas y calizas acumuladas en un me...

The Lower Cretaceous Centenario Formation is a conventional shallow clastic reservoir developed close to the northeastern border of the Neuquén Basin, Argentina. This unit has only been recognized in the subsurface, and is composed of thick bedded sandstones and conglomerates interbedded with shales. Its depositional model has not been deeply studi...

Since the beginning of modern Geology, representation of core and outcrop data in on-scale sedimentary columns became a fundamental tool for sedimentological and stratigraphic analysis of ancient sedimentary successions. Initially, sedimentary logs were sketched in the field or core facilities, and then redrawn in the lab, often requiring long time...

Current depositional models enhance the importance of delta front sandstones as the main clastic reservoir related to marine littoral deltas. In contrast prodelta deposits are considered poor or non-reservoir deposits composing a narrow fringe of fine grained sediments mainly accumulated by fallout from the buoyant plume (hypopycnal flow). Controve...

Intrabasinal and extrabasinal turbidite deposits: origin and distinctive characteristics According to its original conception, turbidites were related to re-sedimentation processes in deep waters. Basically, sediments initially stored in littoral/shallow marine environments were periodically transferred (or re-sedimented) into the inner basin by sl...

Litho: A new software for the description of cores and stratigraphic columns It is a common practice among sedimentologists to represent sedimentary successions in onscale drawings or stratigraphic columns. These stratigraphic columns often synthetize the main characteristics of an outcrop or core, like Lithology, grain size, boundaries, sedimentar...
