The El Masnou Infralittoral sedimentary environment (Barcelona province, NW Mediterranean Sea): morphology and Holocene seismic stratigraphy [PDF]

, 2010
A detailed analysis of the morphology and the Holocene seismic and sequence stratigraphy and architecture of the infralittoral sedimentary environment of the El Masnou coast (Catalonia, NW Mediterranean Sea) was carried out using multibeam bathymetry and

Direct multi-modal inversion of geophysical logs using deep learning [PDF]

Earth and Space Science, 9, e2021EA002186 (2022), 2021
Geosteering of wells requires fast interpretation of geophysical logs, which is a non-unique inverse problem. Current work presents a proof-of-concept approach to multi-modal probabilistic inversion of logs using a single evaluation of an artificial deep neural network (DNN).

Rift sequence stratigraphy

Marine and Petroleum Geology, 2010
Conventional sequence stratigraphy has been developed primarily for passive-margin basins. Despite the conceptual advances within the last 30 years, a suitable model for rift basins has not yet been devised. Many authors have attempted to adapt the passive-margin model to all other tectonic settings, including rifts, despite the fundamental differences

New regional stratigraphic insights from a 3D geological model of the Nasia sub-basin, Ghana, developed for hydrogeological purposes and based on reprocessed B-field data originally collected for mineral exploration [PDF]

www.solid-earth.net/11/349/2020/, 2020
Reprocessing of regional-scale airborne electromagnetic data (AEM) is used to build a 3D geomodel of the Nasia sub-basin. The resulting 3D geomodel integrates all the prior pieces of information brought by electromagnetic data, lithologic logs, and prior geological knowledge.

MACROFAUNA CIRCALITORALE DEL PLIOCENE INFERIORE DI CAPO S. MARCO (SARDEGNA OCCIDENTALE)

Rivista Italiana di Paleontologia e Stratigrafia, 2018
The megafauna recovered from the Lower Pliocene sequence at Capo S. Marco (Sinis Peninsula) are analysed; detailed studies concern taxonomy, stratigraphy and paleoecology.

Employing magma ocean crystallization models to constrain structure and composition of the lunar interior [PDF]

, 2021
The process of lunar magma ocean solidification provides constraints on the properties of distinct chemical reservoirs in the lunar mantle that formed during the early evolution of the Moon. We use a combination of phase equilibria models consistent with experimental results on lunar magma ocean crystallization to study the effect of bulk silicate Moon

Contrasting carbonate depositional systems for Pliocene cool-water limestones cropping out in central Hawke's Bay, New Zealand [PDF]

, 2004
Pliocene limestone formations in central Hawke's Bay (eastern North Island, New Zealand) accumulated on and near the margins of a narrow forearc basin seaway within the convergent Australia/Pacific plate boundary zone.

DATING AND CORRELATION OF THE BALUTI FORMATION, KURDISTAN, IRAQ: Implications for the regional recognition of a Carnian “marker dolomite”, and a review of the Triassic to Early Jurassic sequence stratigraphy of the Arabian Plate

Journal of Petroleum Geology, 2019
L et al. (2019) have published a wide ranging paper on the Triassic of northern Iraq and the relationship of this stratigraphy to that of the entire Arabian Plate.

An integrated sequence stratigraphic, palaeoenvironmental, and chronostratigraphic analysis of the Tangahoe Formation, southern Taranaki coast, with implications for mid-Pliocene (c. 3.4–3.0 Ma) glacio-eustatic sea-level changes [PDF]

, 2005
Sediments of the mid-Pliocene (c. 3.4–3.0 Ma) Tangahoe Formation exposed in cliffs along the South Taranaki coastline of New Zealand comprise a 270 m thick, cyclothemic shallow-marine succession that has been gently warped into a north to south trending,

Sedimentary Environment, Diagenesis, Sequence Stratigraphy, and Reservoir Quality of the Ilam Formation in Dezful Embayment and Abadan Plain in South-West Iran [PDF]

arXiv, 2022
The Ilam Formation Cenomanian to Santonian in age is considered one of the main rock reservoirs of the Bangestan Group in the southwest of Iran. This formation mostly consists of carbonate rocks. To examine the sedimentary environment, diagenesis, sequence stratigraphy, and reservoir quality of Ilam Formation in Dezful embayment and Abadan Plain, four ...
