Phreatic overgrowths on speleothems (POS) from the Mallorca caves: Morphology, mineralogy, and crystal fabric classification

Earth Surface Processes and Landforms, Volume 49, Issue 13, Page 4289-4309, October 2024.
An important number of POS (tracers of past seawater levels) sampled from the coastal caves of Mallorca (Spain) have been studied. A systematization has been done according to their morphology, crystal fabric and mineralogy and to their position above or below the current sea level.

Antecedent Hydrologic Conditions Reflected in Stream Lithium Isotope Ratios During Storms

Geophysical Research Letters, Volume 51, Issue 17, 16 September 2024.
Abstract Antecedent hydrological conditions are recorded through the evolution of dissolved lithium isotope signatures (δ7 ${\delta }^{7}$Li) by juxtaposing two storm events in an upland watershed subject to a Mediterranean climate. Discharge and δ7 ${\delta }^{7}$Li are negatively correlated in both events, but mean δ7 ${\delta }^{7}$Li ratios and ...

Palaeosol Control of Arsenic Pollution: The Bengal Basin in West Bengal, India [PDF]

, 2014
Groundwater in the Bengal Basin is badly polluted by arsenic (As) which adversely affects human health. To provide low-As groundwater for As mitigation, it was sought across 235 km2 of central West Bengal, in the western part of the basin. By drilling 76
