TL;DR: In this paper, the authors focus on a well-characterized upper crustal intrusion, the 15 km2 Lago della Vacca complex (LVC), Adamello batholith, N. Italy, and test this model using a dense sampling strategy and high-precision ID-TIMS U-Pb geochronology of zircon and titanite combined with hafnium isotope and trace element analyses of the same volume of dated mineral.

TL;DR: In both tectonic settings, the results indicate that fractional crystallization, rather than crustal melting, is predominantly responsible for the production of intermediate and felsic magmas, emphasizing the role of mafic cumulates as a residue of crustal differentiation.

TL;DR: Data on lunar zircons indicate differentiation of the lunar crust by 4.51 billion years, indicating the formation of the Moon within the first ~60 million years after the birth of the solar system.

TL;DR: In this paper, chemical abrasion-isotope dilution- thermal ionization mass spectrometry zircon U-Pb dates for volcanic ash beds within the Aramachay Formation of the Pucara Group in northern Peru were used to place precise constraints on the age of the NRB and the duration of the Rhaetian.

TL;DR: In this article, the authors provide new constraints for the amalgamation and stabilization of the eastern Kaapvaal craton in the vicinity of the Barberton greenstone belt circa 3.3-3.1 Ga.
