Interpretation and Reconstruction of Depositional Environment and Petroleum Source Rock Using Outcrop Gamma-ray Log Spectrometry From the Huai Hin Lat Formation, Thailand

Frontiers in Earth Science, 2021
Gamma ray logs are most useful in identifying subsurface lithology and interpreting depositional environments. This study highlights the use of outcrop gamma-ray logs along with outcrop observations and total organic carbon (TOC) analysis to provide the ...

Tectono-stratigraphical evolution of the Çankırı basin (Central Anatolia, Turkey) [PDF]

, 2000
The Izmir-Ankara-Erzincan Suture Zone (IAESZ) demarcates the former position of the northern Neotethys ocean. Along the IAESZ, the Rhodope-Pontide fragments and Taurides collided and amalgamated in the Early Tertiary, leaving behind a number of basins

Quantifying reaction-induced stresses using high angular resolution electron backscatter diffraction (HR-EBSD): Implications for metamorphic hydration reactions [PDF]

, 2019
Hydration reactions are a fundamental metamorphic process and play a critical role in Earth’s tectonics and water budget. Petrological observations previously emphasized that volume expansion was accommodated by pressuresolution or tectonic extension ...

From Surface to Bulk Activation: Tailoring the Porosity and Surface Chemistry of Resorcinol‐Formaldehyde Carbon Sorbents for Atmospheric Water Harvesting

Advanced Materials Interfaces, EarlyView.
A bulk activation route to produce nanoporous carbons for atmospheric water harvesting by incorporating potassium hydroxide during resorcinol‐formaldehyde polycondensation. These high‐oxygen sorbents deliver daily water yields up to 23 L kg−1 day−1 with great cyclability, providing a scalable solution for water production in diverse climates.

Evolution of a highly dilatant fault zone in the grabens of Canyonlands National Park, Utah, USA – integrating fieldwork, ground-penetrating radar and airborne imagery analysis [PDF]

Solid Earth, 2015
The grabens of Canyonlands National Park are a young and active system of sub-parallel, arcuate grabens, whose evolution is the result of salt movement in the subsurface and a slight regional tilt of the faulted strata.

An Examination of the Cs2NaInCl6 Luminescence: Interplay of Self‐Generated In+ and Doped Sb3+, Er3+/Yb3+ Ions

Advanced Optical Materials, EarlyView.
A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.
