SILICATE WEATHERING MACHINE AT WORK
, 2010 We describe a scenario of climate forcing on sedimentation recorded in the late Paleocene–early Eocene Cicogna marine section from the Belluno Basin (NE Italy). Previously published magneto-biostratigraphic data revealed that the ∼81 m Cicogna section extends from Chron C25r to Chron C23r spanning the NP7/NP8-NP12 nannofossil zones (∼52.2–56.6 Ma ...

NMR studies of silicate and aluminosilicate solutions as precursors for zeolites [PDF]
, 1996 The search for a detailed understanding of the mechanism of zeolite synthesis has, over the past two decades, promoted many investigations into the species present in (alumino)silicate solutions.

Adsorption–Desorption Reactions in the Weathering Zone: Implications for Silicate Weathering & the Carbon Cycle [PDF]
The carbonic acid-driven chemical weathering of silicate minerals removes carbon dioxide (CO2) from Earth's atmosphere. The tectonic processes of uplift, exhumation, and erosion modulate the negative feedback relationship between climate, silicate ...

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, Volume 68, Issue 5, Page 908-918, October 2026.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Unveiling Float Glass Staining Induced by an Acid‐Cleaning Product
International Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.ABSTRACT Staining of glass facades is a recurring and significant problem worldwide. This study investigates the causes of staining observed on six laminated float glass samples from four manufacturers (α, β, γ, and δ). Samples from β, γ, and δ were new, whereas those from α (α1, α2, and α3) were taken from a building after service exposure.

Sedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.
