Pegmatites of the Mokromoskovsk granite pluton
Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. ЕкологіяIntroduction. The Mokromoskovsky pluton is composed of light gray granites and dark gray granodiorites. Light gray granites are composed of oligoclase (35-40%), microcline (20-25%), quartz (30-35%), and biotite (2-5%).

Journal of Metamorphic Geology, Volume 44, Issue 6, Page 440-469, July 2026.ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

A geophysical investigation of the Roter Kamm impact crater, Namibia
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1386-1398, July 2026.Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1213-1242, July 2026.Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

Pegmatite mylonites: origin and significance
, 2015 International audiencePegmatites generally behave as resistant objects compared to their host rocks during solid-state deformation. They usually show folding or boudinage within their host rocks, features observed from low-grade to high-grade ...

Battery Energy, Volume 5, Issue 3, May 2026.A simple, chemical‐free method based on a 5‐min microwave treatment and using only water enables the synthesis of Li/Al layered double hydroxides (LDHs) from waste lithium‐ion batteries. These Li/Al LDHs can then be used for lithium extraction from primary resources, supporting a truly sustainable circular economy for lithium.
