Impact of volcanism on the sedimentary record of the Neuquén rift basin, Argentina: towards a cause and effect model [PDF]

open access: yes, 2018
The analysis of volcano-sedimentary infill in sedimentary basins constitutes a challenge for basin analysis and hydrocarbon exploration worldwide. In order to understand the contribution of volcanism to the sedimentary record in rift basins, we study the

Rare Earth Element Characteristics of Shales from Wufeng–Longmaxi Formations in Deep-Buried Areas of the Northern Sichuan Basin, Southern China: Implications for Provenance, Depositional Conditions, and Paleoclimate

open access: yesACS Omega, 2023
To explore the sedimentary environment and the background of the source area of organic-rich shales in the Wufeng–Longmaxi Formations in the northern Sichuan Basin, samples from Well XX1 in the area were subjected to geochemical testing and analysis of ...

Sedimentation of the Lower Cretaceous Xiagou formation and Its Response to Regional Tectonics in the Qingxi Sag, Jiuquan Basin, NW China [PDF]

open access: yes, 2014
Under the constraint of an isochronous sequence stratigraphic framework, sediment infill of the Xiagou Formation reflects the overall control of dynamic tectonic movements and episodic sedimentations in the Qingxi Sag.

SEDucate: sedimentary log exercises for an active learning environment

open access: yesSedimentologika, 2023
Active learning in higher education has been shown to improve students’ learning experience by focusing on a student-centered environment. However, the development of realistic activities that simulate the complexity of real world examples while being ...

Depositional environment and sequence stratigraphy of the Asmari Formation in Kuh-e Asmari and Kuh-e Gurpi surface sections [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2016
In this research the sedimentary successions of the Asmari Formation with the age of Oligocene – Miocene in two outcrops of kuh–e Asmari, located in the Dezful embayment with a thickness of 349 m and kuh–e Gurpi (Pabdeh valley), located at the Izeh

Neogene stratigraphic architecture and tectonic evolution of Wanganui, King Country, and eastern Taranaki Basins, New Zealand [PDF]

open access: yes, 2004
Analysis of the stratigraphic architecture of the fills of Wanganui, King Country, and eastern Taranaki Basins reveals the occurrence of five 2nd order Late Paleocene and Neogene sequences of tectonic origin.

Facies analysis, biostratigraphy, and provenance of the late Neogene Seulimeum Formation, Northwest Aceh basin, Sumatra (Indonesia)

open access: yesHeliyon, 2023
A sedimentological, biostratigraphic, and petrographical investigation was conducted on exposed sedimentary rocks in the Seulimeum Formation in the Northwest Aceh Basin, Sumatra. Sedimentary facies analysis suggests a deep-marine depositional environment

The anatomy of exhumed river-channel belts: Bedform to belt‐scale river kinematics of the Ruby Ranch Member, Cretaceous Cedar Mountain Formation, Utah, USA [PDF]

open access: yes, 2020
Many published interpretations of ancient fluvial systems have relied on observations of extensive outcrops of thick successions. This paper, in contrast, demonstrates that a regional understanding of palaeoriver kinematics, depositional setting and ...
