Impact of Climate Change on Past Indian Monsoon and Circulation: A Perspective Based on Radiogenic and Trace Metal Geochemistry

Atmosphere, 2021
The Indian summer monsoon (ISM), one of the dramatic illustrations of seasonal hydrological variability in the climate system, affects billions of lives.

A Crustal Control on the Fe Isotope Systematics of Volcanic Arcs Revealed in Plutonic Xenoliths From the Lesser Antilles

Frontiers in Earth Science, 2022
Lavas produced at subduction zones represent the integration of both source heterogeneity and an array of crustal processes, such as: differentiation; mixing; homogenisation; assimilation.

Insights into combined radiogenic and stable strontium isotopes as tracers for weathering processes in subglacial environments [PDF]

, 2016
This study reports stable and radiogenic strontium isotope behaviour in the dissolved load and suspended sediments from the subglacial outflow of the Lemon Creek glacier (Juneau Ice Field, Alaska) over a single melt season.

WEATHERING, RADIOGENIC ISOTOPES, AND MARINE RECORDS OF GLACIAL DYNAMICS [PDF]

, 2021
Glacial advance and retreat is related to numerous climate system feedbacks; yet, this dynamic glacial activity tends to erase its own terrestrial record.

Radiogenic isotopes: Tracers of past ocean circulation and erosional input [PDF]

, 2002
The radiogenic isotope composition of dissolved trace metals in the ocean represents a set of relatively new and not yet fully exploited tracers with a large potential for oceanographic and paleoceanographic research on timescales from the present back ...

Variability of carbonate diagenesis in equatorial Pacific sediments deduced from radiogenic and stable Sr isotopes [PDF]

, 2015
The recrystallisation (dissolution–precipitation) of carbonate sediments has been successfully modelled to explain profiles of pore water Sr concentration and radiogenic Sr isotope composition at different locations of the global ocean.

Insights into the Galápagos plume from uranium‐series isotopes of recently erupted basalts

Geochemistry, Geophysics, Geosystems, 2011
Uranium‐series isotopes (238U‐230Th‐226Ra‐210Pb), major element, trace element, and Sr‐Nd isotopic data are presented for recent (
