Temporal Changes in Europa's Ice Shell Thickness: Insights From Models of Convection

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Europa is characterized by a thin ice Ih shell overlying a subsurface ocean and a large solid core. Estimates of the outer ice shell's thickness range from a few kilometers to several tens of kilometers, with strong implications for Europa's thermal and geological history.

Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Quantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite. However, constraining the amount and composition of common Pb, as well as the timing of its entrapment, remains a persistent challenge.

From Collision to Subduction: Thermal‐Kinematic Inversions Constrain Plate Boundary Structure and Dip‐Slip Activity in Southwestern New Zealand

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Constraints on three‐dimensional fault system geometry and kinematics are required to understand both long‐term tectonics and contemporary seismic hazard. In many cases, these parameters must be inferred from a combination of different data or analyses.

Measurement of isomeric ratios in 232Th photofission products

Nuclear Physics and Atomic Energy, 2002
Measurement of activity of 232Th photofission products with T1/2 = 1 min ÷ 10 h has been carried out using γ-spectroscopy technique. The targets were irradiated by bremsstrahlung γ-quanta from Mevatron KD2 linear electron accelerator with boundary energy of 23 MeV. Using obtained data about photofission fragments yield isomeric ratios for 117In, 130Sb,
