Image Endmembers and the Scene Model
Canadian Journal of Remote Sensing, 1999 Le demixage des pixels requiert des spectres de reference (endmembers) precis et bien caracterises et un modele de scene a une echelle spatiale appropriee mais beaucoup plus d'attention a ete accorde au premier element qu'au dernier. En l'absence d'un modele de scene a priori, il n'est pas clair comment les spectres de reference devraient etre ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The India–Asia collision continuously loads the Tibetan Plateau (TP), driving its Cenozoic eastward growth. This process has caused extensive crustal deformation and a diverse magmatic response. Here, we report on newly identified 35−6.5 Ma granitoids from Kangding area in southeastern (SE) TP.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract With over a century since the last major rupture affecting the wider Los Angeles region, tectonic stress has steadily built along the southern San Andreas and San Jacinto fault systems, raising concerns of an imminent large earthquake. Cajon Pass, located at the junction of these faults, represents a critical site for potential through‐going ...

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is

Lunar Crustal Formation by Melt Migration and Differentiation Within a Stagnant Lid
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract The lunar anorthosite highlands represent the Moon's primary crust, which formed during the solidification of a magma ocean following the Moon‐forming giant impact. However, the canonical model of anorthite flotation in the crystallizing magma ocean often struggles to reproduce the long > ${ >} $200 Myr solidification timescale required by the

Controls on Valley‐Floor Width in the Western Andes
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract Degradation of Arctic permafrost due to global warming and sea level rise could trigger positive feedbacks, exacerbating climate change. However, uncertainties remain on how permafrost systems may respond because we lack a complete understanding of the permafrost‐climate feedback.

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract The deep continental subsurface hosts a large, diverse, and poorly characterized microbiome. The geochemistry and microbiology of deep subsurface sites are closely linked and influenced by geological, hydrological, and anthropogenic factors. The Deep Mine Microbial Observatory (DeMMO; Lead, SD) was established in 2015 to provide stable portals
