U-Pb age constraints on dinosaur rise from south Brazil

Gondwana Research, 2018
Abstract Triassic dinosaurs from South Brazil are considered as some of the oldest known worldwide, but their precise correlation to other early dinosaur occurrences have proven difficult. The problem of such long-distance faunal correlations has been exacerbated by reliance on an equivocal tetrapod biostratigraphy and the lack of palynomorphs and ...

U-Pb age of the Baltoro granite, northwest Himalaya, and implications for monazite U-Pb systematics

Geology, 1989
The Baltoro granite is a major late- to post-tectonic plutonic phase of the Karakoram batholith of the northwest Himalaya in northern Pakistan. U-Pb zircon analyses indicate both emplacement at 21.0 ±0.5 Ma and significant Precambrian zircon inheritance.
