Genetic mechanism of bicyclic sesquiterpanes in Upper Triassic source rock of Yinan 2 well from the Kuqa Depression of Tarim Basin, China

Scientific Reports
Bicyclic sesquiterpanes are widely distributed in terrigenous sedimentary organic matter and are serve as valuable biomarker in the field of organic geochemistry.

Petrological and Geochemical Constraints on the Origin of Early Cretaceous Volcanic Rocks in the Central‐East Asia: Implications for Crustal Growth and Evolution

Geochemistry, Geophysics, Geosystems, 2018
New petrological and geochemical data for Early Cretaceous volcanic rocks in the North China Craton (NCC) combined with published data of cotemporaneous volcanic rocks in the NCC and eastern Central Asian Orogenic Belt (ECAOB) are used to understand ...

South Asian monsoon history over the past 60 kyr recorded by radiogenic isotopes and clay mineral assemblages in the Andaman Sea [PDF]

, 2015
The Late Quaternary variability of the South Asian (or Indian) monsoon has been linked with glacial‐interglacial and millennial scale climatic changes but past rainfall intensity in the river catchments draining into the Andaman Sea remains poorly ...

Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]

, 2006
During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.

Early maturation processes in coal. Part 1: Pyrolysis mass balances and structural evolution of coalified wood from the Morwell Brown Coal seam [PDF]

, 2009
In this work, we develop a theoretical approach to evaluate maturation process of kerogen-like material, involving molecular dynamic reactive modeling with a reactive force field to simulate the thermal stress. The Morwell coal has been selected to study

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, EarlyView.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

The Depositional Record, EarlyView.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.
