Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone

open access: yesTerra Nova, Volume 38, Issue 2, Page 106-115, April 2026.
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the conservation conditions of foods made with eggs or egg products in retail establishments

open access: yesFood Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Royal Decree 1021/2022, which regulates certain hygiene requirements for the production and marketing of foodstuffs in retail establishments, establishes that, in retail establishments, food made with raw egg subjected to heat treatment where a temperature equal to or greater than 70°C is reached for 2 seconds in the centre of the product or ...

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on nutritional risks for women during menopause, perimenopause and postmenopause

open access: yesFood Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Menopause is the time when a woman transitions from the reproductive stage of life to the non‐reproductive state. It is characterised by significant hormonal changes, which can affect a woman's physical, emotional, mental and social well‐being.

Mechanochemical Enhancement of Siderite‐To‐Magnetite Conversion in Faults

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip. However, the thermochemical kinetics of magnetic minerals subjected to shear deformation in hydrothermal fluids‐conditions typical of natural faults ‐ remains poorly understood, hindering accurate temperature estimates.

Size‐Dependent Melting Behavior of Ultrafine Fault Rocks

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Dynamic weakening during earthquake ruptures is essential for accommodating fault slip and controlling seismic energy release. This weakening is localized within narrow principal slip zones (PSZs) that commonly contain nanoparticles in both natural and experimental faults.
