TL;DR: In this article, new SHRIMP and TIMS zircon ages, 40Ar/39Ar ages, and eclogite locations contribute significantly to our understanding of the ultrahigh-pressure Dabie Shan.

TL;DR: The Qinling orogen preserves a record of late mid-Proterozoic to Cenozoic tectonism in central China as mentioned in this paper, where high pressure metamorphism and ophiolite emplacement assembled the Yangtze craton, including the lower Qinling unit, into Rodinia during the ∼1.0 Ga Grenvillian orogeny.

TL;DR: In this article, the authors measured rare earth element (REE) abundances for zircons from a range of common crustal igneous rock types from different tectonic environments, as well as kimberlite, carbonatite, and high-grade metamorphic rocks, to assess the potential of using zircon REE characteristics to infer the rock types present in sediment source regions.

TL;DR: The largest tract of ultrahigh pressure rocks, the Dabie-Hong'an area of China, was exhumed from 125 km depth by a combination of normal-sense shear from beneath the hanging wall Sino-Korean craton, southeastward thrusting onto the footwall Yangtze craton and orogen-parallel eastward extrusion as discussed by the authors.

TL;DR: Secondary ion mass spectrometry (SIMS) is a versatile technique for measuring the chemical and isotopic composition of solid materials on a scale of a few microns as mentioned in this paper.
