NATURE OF THE LATE CARBONIFEROUS TO TRIASSIC MAGMATISM ALONG THE NORTHERN MARGIN OF THE NORTH CHINA BLOCK: LINK WITH THE EVOLUTION OF THE CENTRAL ASIAN OROGEN

Геодинамика и тектонофизика, 2017
There are two episodes of magmatism along the northern margin of the North China block during the Late Carboniferous to Late Triassic, one at 310–250 Ma (Late Carboniferous to Permian) and the other at 235–210 Ma (Late Triassic).

TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology

Rapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.

Mechanical Performance Degradation and Microstructural Evolution of Grout-Reinforced Fractured Diorite Under High Temperature and Acidic Corrosion Coupling

Buildings
The long-term stability of grout-reinforced fractured rock masses in acidic groundwater environments after tunnel fires is critical for the safe operation of underground engineering. In this study, grouting reinforcement tests were performed on fractured

Learning Across the Divide: Understanding Knowledge Sharing Through Petrographic Analysis on Ceramics From the Rhine‐Meuse Delta During the Middle to Late Neolithic Transition (3400–2200 bce)

Archaeometry, Volume 68, Issue 6, Page 1251-1264, December 2026.
ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.

A Geophysical Crustal Model of Central Italy for Geoneutrino Predictions in Borexino

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Predicting the geoneutrino signal at underground detectors requires a local crustal reference whose precision matches the experimental uncertainty. The current Borexino reference is 15 years old and deterministic. We replace it with GUESS, a probabilistic 3‐D model of the Gran Sasso region, built by Bayesian inversion of multi‐source ...

Petrogenesis of Middle Triassic intermediate-mafic igneous rocks in East Kunlun, Northern Tibet: Implications for the crust growth and Paleo-Tethyan orogeny

Geosystems and Geoenvironment
Triassic intermediate-mafic igneous rocks are sporadically exposed in the East Kunlun Orogen Belt (EKOB), and their petrogenesis and geological implications for the Paleo-Tethyan orogeny are not well constrained.

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, Volume 37, Issue 16, Page 11867-11884, October 2026.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...
