Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.Abstract The highly variable spatial composition of desert soils remains a major source of uncertainty in estimates of dust radiative forcing. Existing soil mineralogy data sets used in climate models are limited by sparse ground observations and coarse spatial resolution.

Mica-chlorite intermixing and altered chlorite from the Nevado-Filabride micaschists, Southern Spain
, 1991 12 páginas, 4 figuras, 2 tablasMinerals with biotite-like optical properties occur in the Nevado-Filabride micaschists. The grains are highly pleochroic, variable in colour from light yellow to deep red, and strongly recall the descriptions given for ...

Chlorite chemical refinement during giant quartz vein formation [PDF]
The major elemental composition of chlorite is widely used for petrogenetic investigations on low-temperature geological processes. However, compositional variations of chlorite within a given tectonic environment are common and, when overlooked, can ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

The Trimouns Talc-Chlorite Deposit
International audienceThe recent results on metasomatism and deformation at Trimouns show unambiguously that the formation of talc-chlorite mineralization is associated with the rifting phase at the beginning of the Alpine cycle (250 Ma current), and ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Mineralogy of Historic Scheelite Mine Tailings at Glenorchy, Otago, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Otago Schist orogenic mineral deposits with scheelite and gold in the Glenorchy area are mineralogically and geochemically similar to, but structurally different from, those at the active Macraes gold mine in East Otago. Glenorchy veins were mined for scheelite up to 1970s, and an abandoned processing battery site at Glenorchy is now being managed for ...

AGU Advances, Volume 7, Issue 3, June 2026.Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).
