Tracing Groundwater‐Surface Water Interactions in a Volcanic Maar Lake Using Stable Isotopes and 222Rn

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 12, December 2024.
Abstract Isotope hydrological studies to understand groundwater‐surface water interactions in tropical, high‐elevation catchments are limited. These interactions are important in controlling lake water residence time, aqueous biogeochemistry, and water availability for downstream communities and ecosystems. To better comprehend the complexity of spatio‐

Sedimentary dolomite in Western Australia and the dolomite problem: Genesis of channel and playa uranium deposits

Sedimentology, Volume 71, Issue 7, Page 2248-2289, December 2024.
ABSTRACT Quaternary to Recent sedimentary dolomite in groundwater calcrete and saltmarsh sediments of Lake Way and Lake Maitland, Western Australia, provide new information about the formation of low‐temperature dolomite. Dolomite can form through numerous pathways depending on the depositional and diagenetic environment.
