Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.

We assessed Cyperaceae species composition, richness and endemicity across closed (forest), dry open (dry grasslands, rocky outcrops, bare dry soils), and wet open (marshes, swamps, wet grasslands, riparian areas) habitats in Isalo National Park and the Itremo Massif Protected Area, both in Madagascar's Central Highlands.

Moon's volcanic history revealed in glassy spherules from Apollo 17 soil 76501
Abstract Rapidly quenched droplets of pyroclastically erupted lava are common in lunar regolith at landing sites proximal to the maria. Here, we document the U‐Pb chronologies, major element, and trace element compositions of picritic glassy particles from Apollo 17 regolith sample 76501. These particles are dominated by high‐Ti compositions similar to

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...
