Microtextural Studies of Feldspar in Ordinary Chondrites

, 2018
Ordinary chondrites contain an important record of events that took place during the earliest period of solar system evolution. These include primary processes, such as chondrule formation, and secondary processes, those that affected asteroids after ...

Supercritical‐flow structures in a Cretaceous submarine channel–lobe transition zone, Point Loma Formation, California

The Depositional Record, Volume 12, Issue 3, June 2026.
We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...

Embodied Intelligence for Soil Health toward Sustainable Smart Agriculture: Sensing the Soil with Flexible Geotextiles Sensors

Global Challenges, Volume 10, Issue 6, June 2026.
This review examines the transition from rigid to flexible soil sensing technologies in the context of soil as a dynamic and heterogeneous environment. By integrating sensor types, sensing modalities, materials, fabrication and deployment strategies, and IoT‐enabled energy and communication approaches, it highlights geotextiles as scalable sensing ...

Feldspar : mineral composition, geology and petrogenesis significance

In this book, the authors present current research in the study of the mineral composition, geology and petrogenesis significance of feldspar, a group of rock-forming tectosilicate minerals that make up as much as 60% of the Earth's crust.
