Boreas, EarlyView.The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Meteoritics &Planetary Science, EarlyView.Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

La Granja, 2013 Como requisito previo para la consecución de imágenes tomográficas se estudian tres modelos de Moho. Para la región de Ecuador se analizan el modelo gravimétrico de Chambat-Valette, un modelo de velocidades de propagación de ondas sísmicas en tres dimensiones y un modelo de observaciones gravimétricas satelitales.

Australia's Moho: A test of the usefulness of gravity modelling for the determination of Moho depth
Tectonophysics, 2013 Abstract In general, seismic methods provide a reliable way to image the crust–mantle interface, which is marked by a rapid increase in seismic velocity (the Moho). However, the coverage provided by seismic networks is necessarily limited due to access difficulties, and the cost and labour involved in collecting data.

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA
Meteoritics &Planetary Science, EarlyView.Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract We investigate the structure and tectonic environment in the crust and upper mantle beneath the North China Craton (NCC) by conducting a full‐waveform inversion of teleseismic P and its coda waves from densely distributed broadband seismic stations. A high‐resolution model involving P‐ and S‐wave velocities as well as density is constructed by

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Klyuchevskoy Volcanic Group (KVG) is one of the world's largest clusters of subduction‐zone volcanoes and hosts a complex trans‐crustal magmatic system. Using a machine‐learning–based detection workflow applied to data from the KISS seismic experiment in 2015–2016, we obtained an enhanced earthquake catalog for KVG volcano‐magmatic activity ...
