DOI: 10.1016/j.epsl.2017.05.005
Abstract: High-precision measurements of 142Nd/144Nd in picrites from the Baffin Bay region that contain the highest 3He/4He ratios yet measured in terrestrial mantle-derived rocks are indistinguishable from the value measured in the terrestrial standard and other… read more here.

DOI: 10.1016/j.epsl.2018.12.012
Abstract: Abstract The hydrogen isotope value (δD) of water indigenous to the mantle is masked by the early degassing and recycling of surface water through Earth's history. High 3He/4He ratios in some ocean island basalts, however,… read more here.

DOI: 10.1016/j.epsl.2020.116722
Abstract: Abstract The transfer of large volumes of fluid to the overriding lithosphere during flat-slab subduction should drastically alter the physical and chemical properties of continental margins. However, this process is poorly understood and without active… read more here.

DOI: 10.1073/pnas.2113877119
Abstract: Significance Our regional-scale geochemical dataset (3He/4He) resolves the geometry of the continental collision between India and Asia. Geophysical images have led to contradictory interpretations that India directly underthrusts Tibet as a horizontal plate or India… read more here.
