Multi‐Scale Electrical Conductivity Model of the Contiguous United States

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The completion of the Magnetotelluric (MT) USArray across the contiguous US enables continental‐scale 3‐D imaging of the asthenosphere‐lithosphere electrical structure. We present a novel 3‐D model of the contiguous United States (MECMUS), derived from a single inversion of the now‐completed USMTArray data set.

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.

Ultrahigh‐Temperature Metamorphism and Near‐Isobaric Cooling of Garnet‐Orthopyroxene Granulite Xenoliths in the Sancheong Anorthosite, Yeongnam Massif, Korea

Journal of Metamorphic Geology, Volume 44, Issue 1, Page 20-46, January 2026.
ABSTRACT Elevated heat flow associated with mafic magmatism in accretionary orogens has often been proposed as a driving mechanism for (ultra)high‐temperature (UHT) metamorphism and anatexis. The Sancheong–Hadong complex, located in the southern Yeongnam Massif, Korea, consists of a ca.
