Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

open access: yesGeological Journal, Volume 61, Issue 5, Page 1291-1309, May 2026.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

Study of Galena Ore Powder Sintering and Its Microstructure

open access: yesMetals
Galena is a natural mineral enriched with lead sulfide (PbS). It typically forms in hydrothermal veins associated with igneous rocks and can also occur as a gangue mineral in other ore deposits.

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Release Behavior of Lead and Mineral Transformation Characteristics of Micro-Scale Galena in Different Media

open access: yesYankuang ceshi
The weathering behavior of galena, as the main lead ore, directly affects the migration and fate of heavy metal Pb in the environment. Weathering environment and time both affect the weathering products of galena.

Mass Addition to Timpanogos Rock Glacier: Debris‐Covered Snow and the Importance of Interannual Variability in Headwall Erosion and Climate

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The processes of ice incorporation into rock glaciers have been difficult to quantify in both permafrost and non‐permafrost conditions. Here, we develop a numerical model that regardless of the presence of permafrost, reveals how debris eroded from hillslopes and deposited on snow can add ice mass to rock glaciers in pulses.

‘You Load Sixteen Tons, What Do You Get?’. The Jodłowno Hoard (Pomerania, Poland) as Evidence of Long‐Distance Contacts in the Early Iron Age

open access: yesArchaeometry, Volume 68, Issue 2, Page 193-211, April 2026.
ABSTRACT This study presents multifaceted analyses of metal artefacts from the Jodłowno Hoard (Northern Poland), revealing that the metal originated from Iberian polymetallic ore deposits. Transported as raw ingots via Atlantic maritime routes, this copper was reworked locally into regionally distinctive forms.
