Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Mineralization Characteristics of the Li‐rich Muscovite Granite in the Mufushan Batholith, Central China: Insights into the Rare Metal Mineralization Models of Batholithic Complex

Acta Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.
Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Gestational Age‐Dependent Effects of Antenatal Magnesium Sulfate on Fetal S100B Levels: An Observational Study Using Cord Serum

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 2, February 2026.
ABSTRACT Aim Magnesium sulfate (MgSO4) is widely used for fetal neuroprotection in preterm births before 32 weeks of gestation, yet it remains unclear whether its effect depends on gestational age. S100 calcium‐binding protein B (S100B), a protein secreted by astrocytes, is recognized as a biomarker of neural distress.

Re-Os Molybdenite Ages of the Shenduolong Skarn Mo-Pb-Zn Deposit and Geodynamic Framework, Qinghai Province

Yankuang ceshi, 2014
The Shiduolong skarn Mo-Pb-Zn deposit is located in the multi-metal metallogenic belt of E'lashan. The precise age of the ore deposit limits our understanding of the ore-forming processes and geodynamical setting. In spite of the K-Ar methods of analysis

Geochemistry and U–Pb Zircon Geochronology of Granite at the Pilok Sn–W Deposit, Thailand: Implications for Late Triassic Tin Metallogenesis

Resource Geology, Volume 76, Issue 1, January/December 2026.
Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western

Geological and Isotopic Constraints on the Metallogenic Evolution of the Proterozoic Sediment-Hosted Pb-Zn (Ag) Deposits of Brazil [PDF]

Gondwana Research, 1999
Abstract Integrated studies of seven Proterozoic sediment-hosted, Pb-Zn-Ag sulfide deposits of Brazil, permit the estimation of the age of the hosting sequence and the mineralization, the nature of the sulfur and metal sources, the temperature range of sulfide formation and the environment of deposition.

Trace Elements and Sulfur Isotopes of Sulfides at the Leon Sediment‐Hosted Gold Deposit, Ratatotok District, North Sulawesi, Indonesia: Constraints on the Genesis of Ore Formation

Resource Geology, Volume 76, Issue 1, January/December 2026.
The Leon deposit is interpreted as a sediment‐hosted gold deposit with a probable distal intrusion‐centered setting. Hydrothermal fluids migrated through fractures and bedding planes, likely leached sulfur and metals from andesitic rocks, and formed orebodies along bedding planes and at limestone–andesite contacts controlled by permeability contrasts ...
