Petrographic relations between muscovite-biotite granite and hornblende-biotite granite.
The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1985 The relationship between muscovite-biotite granite and hornblende-biotite granite was investigated. Chemical analyses satisfying the following three conditions collected from the literature were used to compare the two types of granite; 1) The chemical analysis was of a rock called “granite” by the original author.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The southeastern Tibetan Plateau has undergone complex deformation due to the India‐Eurasia collision. Although late‐stage internal rotations are documented in the Lanping‐Simao Terrane to the south, it remains unclear whether similar processes have affected the north.

Delamination of Vermiculite into Ultrahigh‐Aspect‐Ratio Nanosheets
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.Efficient ion exchange allows for thermodynamically driven delamination of vermiculite into high‐aspect ratio nanosheets. The applicability of sustainable materials in the packaging industry is currently limited by the poor gas barrier performance of most biodegradable polymers.

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 ...

Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.
