Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, Volume 55, Issue 4, Page 1208-1227, October 2026.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2531-2548, October 2026.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...
