A comprehensive analysis of the sedimentology, petrography, diagenesis and reservoir quality of sandstones from the Oligocene Xiaganchaigou (E3) Formation in the Lengdong area, Qaidam Basin, China

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The sandstone from the Oligocene Xiaganchaigou Formation (E3) in the Lengdong area, Qaidam Basin, China, is extensively distributed and acts as an effective regional reservoir for hydrocarbon accumulation.

Influence of Regional Tectonics on The Geological Formations of The Locality of Mabuku in Beni Territory

open access: yesIndonesian Journal of Earth Sciences, 2022
The locality of Mabuku is located in the eastern DRC, in a landscape where tectonic effects are visible. The main cause of this environmental disturbance is known as tectonics.

The Effect of Obliquity of Slip in Normal Faults on Distribution of Open Fractures

open access: yesFrontiers in Earth Science, 2019
Close to surface, cohesive rocks fail in extension, which results in open fractures that can be several tens of meters wide, so-called massively dilatant faults. These open fractures make fault slip analysis in rifts challenging, as kinematic markers are

Multiphase boudinage: a case study of amphibolites in marble in the Naxos migmatite core [PDF]

open access: yesSolid Earth, 2018
In multiply deformed terrains multiphase boudinage is common, but identification and analysis of these is difficult. Here we present an analysis of multiphase boudinage and fold structures in deformed amphibolite layers in marble from the migmatitic ...

New insights into salt tectonics in the northern Dutch offshore: a framework for hydrocarbon exploration [PDF]

open access: yes, 2018
The northern Dutch offshore is an area that has seen less hydrocarbon exploration activity than other areas of The Netherlands. Acquisition of a new regional 3D seismic dataset allowed further testing and re-evaluation of established geological concepts ...

Tube coalescence in the Jingfudong lava tube and implications for lava flow hazard of Tengchong volcanism

open access: yesInternational Journal of Speleology, 2016
Tube-fed structure occurs as a general phenomenon in Tengchong basic lavas, such as lava tubes, lava plugs and tube-related collapse depressions. We deduced the development of Laoguipo lava flows, which is the longest lava tube (Jingfudong lava tube ...

The link between tectonics and sedimentation in back-arc basins: New genetic constraints from the analysis of the Pannonian Basin [PDF]

open access: yes, 2016
The architecture of sedimentary basins reflects the relationship between accommodation space and sediment supply, their rates and localization being variable during basin evolution. The mechanisms driving the interplay between tectonics and sedimentation

Correlation of peat sections of the Lower Priamurye based on the results of calculation of relative paleointensity

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
The paper considers the possibility of determining the age and correlating peat sections by solving the inverse problem of magnetostratigraphy based on the findings of comprehensive (palaeomagnetic, petromagnetic, microprobe, and radiocarbon) studies on ...

Observing eruptions of gas-rich compressible magmas from space

open access: yesNature Communications, 2016
Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and
