Proximal to distal grain‐size distribution of basin‐floor lobes: A study from the Battfjellet Formation, Central Tertiary Basin, Svalbard

The Depositional Record, 2022
The grain‐size distribution of sediment particles is an important aspect of the architecture of submarine fans and lobes. It governs depositional sand quality and reflects distribution of particulate organic carbon and pollutants.

Lowstand Turbidites and Delta Systems of the Itararé Group in the Vidal Ramos region (SC), southern Brazil

Brazilian Journal of Geology
Turbidites have captioned the attention of sedimentologists during the last decades due their importance as hydrocarbon reservoirs. However, their relationship to delta systems still deserves further studies.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Turbidite sedimentology, biostratigraphy and paleoecology: A case study from the Oligocene Zuberec Fm. (Liptov Basin, Central Western Carpathians)

Geologica Carpathica, 2019
Outcrops of a thick turbiditic succession are exposed on the northern bank of the Liptovská Mara reservoir near Liptovská Ondrašová and Ráztoky. The section consists of rhythmic, predominantly thin- to medium-bedded turbidites of the Rupelian age.

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland

Boreas, EarlyView.
Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

Tectonic-sedimentary approach as a basis to study thinly bedded reservoirs with complex geological structure

Известия высших учебных заведений: Нефть и газ, 2020
The article is focused on studies of features of the formation of heterogeneous geological structures namely the "lake-type" turbidite reservoirs, with complex thin-layered structure.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Late Miocene sedimentary record of the Danube/Kisalföld Basin: interregional correlation of depositional systems, stratigraphy and structural evolution

Geologica Carpathica, 2016
The Danube / Kisalföld Basin is the north-western sub-basin of the Pannonian Basin System. The lithostratigraphic subdivision of the several-km-thick Upper Miocene to Pliocene sedimentary succession related to Lake Pannon has been developed independently

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

Key problems of the eastern part of the Crimea Mountain stratigraphy. New micropaleontologic information for dating of flysh rocks

Геофизический журнал, 2014
On the base of French-Ukrainian collaboration (DARIUS program), in the eastern part of the Crimea Mountain the first stage of field work was performed, during which the samples of flysch rocks were taken for micropaleontological analysis ...
