Subduction Initiation Volcanism Leading to Development of the Talkeetna Arc, Lower Shuyak Formation, Kodiak Archipelago, Alaska

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Climate and Tectonic Forcing of Depositional Evolution in the Southern North China Basin Since ∼3 Ma

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Marginal basins provide sensitive yet incomplete records of climate and tectonic forcing, and the southern North China Basin provides an ideal setting to decode these interactions since the late Pliocene. A 135.6‐m borehole sequence, the XiaoQian (XQ) core, recovered from the Fuyang region, was dated using AMS 14C, OSL, and ESR, supplemented ...

Law and Mechanism of Different Electric Field Modes Enhancement Alkaline Leaching Sandstone-type Uranium Ore

Yuanzineng kexue jishu
China’s uranium resources are rich in reserves and deposits, but they are mainly low-grade uranium ores with low content of uranium. Sandstone-type uranium ores are mainly mined by in-situ leaching (ISL), but when the carbonate content is high, their ...
