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.

Late Mesozoic adakite granites of the southern frame of the eastern flank of the Mongol-Okhotsk orogenic belt: material composition and geodynamic conditions of formation

Геодинамика и тектонофизика, 2020
Granitoids of the Magdagachi complex were studied using new and published petrochemical, geochemical and isotopic (Sm-Nd, Rb-Sr) data. Granitoid samples were taken from the southern frame of the eastern flank of the Mongol-Okhotsk orogenic belt (MOOB ...

Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, Volume 24, Issue 5, Page 669-692, October 2026.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

Paleomagnetism of the Scourie Dykes, Lewisian Foreland, NW Scotland: Constraints on Early Paleoproterozoic Paleogeography of Kenorland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.

EARLY NEOPROTEROZOIC GRANITOIDS IN THE RYAZANOVSKY MASSIF OF THE YENISEI RIDGE AS INDICATORS OF THE GRENVILLE OROGENY AT THE WESTERN MARGIN OF THE SIBERIAN CRATON

Геодинамика и тектонофизика
Studies of the geological history of the Yenisei Ridge are important not only for understanding the tectonic evolution of mobile belts at the boundaries of ancient cratons but also for problem solving whether the Siberian craton was a part of the Rodinia
