Early Jurassic large igneous province carbon emissions are constrained by sedimentary mercury

Tue, 03/12/2024 - 00:00

Nature Geoscience, Published online: 12 March 2024; doi:10.1038/s41561-024-01379-4

The carbon emissions of large igneous province magmatism are commonly associated with severe environmental crises. We developed a technique that used sedimentary mercury records to estimate these carbon fluxes through time and found that they are smaller and/or slower than assumed, which suggests that the influence of carbon-cycle feedback processes is underestimated in current models.

Ultralow velocity zone and deep mantle flow beneath the Himalayas are linked to a subducted slab

Wed, 02/28/2024 - 00:00

Nature Geoscience, Published online: 28 February 2024; doi:10.1038/s41561-024-01387-4

Through the detection of postcursors of shear waves diffracted at the core–mantle boundary, a zone of ultralow seismic velocities has been identified at the base of the mantle beneath the Himalayas. The presence of this zone is probably linked to a subducted slab remnant that is driving mantle flow in the region.
