LA-ICP-MS U-Pb geochronology of detrital zircons from the Jining Complex, North China Craton and its tectonic significance [PDF]
, 2006 LA-ICP-MS U-Pb zircon dating and cathodoluminescene (CL) image analysis were carried out to determine the protolith and metamorphic ages of high-grade Al-rich gneisses, named as "khondalites", from the Jining Complex of the North China Craton (NCC).

Volcanic Unrest After the 2021 Eruption of La Palma
Geophysical Research Letters, Volume 51, Issue 11, 16 June 2024.Abstract La Palma, Canary Islands, had its largest historical eruption in 2021. From January 2022 to May 2023 there were >2,100 seismic events, primarily at depths ≤20 km, prompting us to update the deformation and modeling study, using interferometric synthetic aperture radar observations and a last generation interpretation tool.

Magmatic Storage and Volatile Fluxes of the 2021 La Palma Eruption
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.Abstract The 2021 La Palma eruption (Tajogaite) was unprecedented in magnitude, duration, and degree of monitoring compared to historical volcanism on La Palma. Here, we provide data on melt inclusions in samples from the beginning and end of the eruption to compare the utility of both melt and fluid inclusions as recorders of magma storage.

Petrologia do Maciço Alcalino de Itapirapuã, SP [PDF]
, 2017 The alkaline rock complex of Itapirapua covers an area of approximately 4 km², with irregular shape, and elongated NW-SE. It was intruded in a large body of granitic rocks. The alkaline intrusion consists exclusively of undersatured rocks, predominantly nepheline syenites with variable amounts of titaniferous garnet (melanite). Basic alkaline varieties
