Journal of Metamorphic Geology, EarlyView.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

KNaCaSi4O10 Obtained From Crystallization Experiments in the Quaternary System K2O–Na2O–CaO–SiO2
Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.The compound KNaCaSi4O10 has been identified in crystallization experiments of glasses in the quaternary system K2O–Na2O–CaO–SiO2 and has undergone structural characterization. Vibrational spectroscopic data have been acquired and interpreted using density functional theory (DFT) calculations.

Campiglia Marittima Skarn (Tuscany): A Challenging Example for the Evolution of Skarn-Forming Models
Minerals, 2023 Campiglia Marittima (hereafter Campiglia) has a long record of attracting interest on its ore deposits that have been intermittently exploited from the Copper Age to the late XX century. Since the XIX century, Campiglia has been a key locality for the debate on skarn-forming processes due to the presence of mining activities ensuring access to ever new
