TL;DR: The authors reported a 3.6 Ga true granite from the Archaean Bastar craton in India, which is relatively undeformed and is assumed to be a potassium-poor tonalite-trondhjemite-granodiorite.
Abstract: Granitoids in the early Archaean are believed to be potassium-poor tonalite–trondhjemite–granodiorite rocks. Only after continental crust attained sufficient thickness did true (relatively potassium-rich) granites form. No record of true granite prior to 3.4 Ga is available. We report a 3.6 Ga true granite from the Archaean Bastar craton in India. In contrast to the typical early Archaean granitoids, which are commonly deformed into gneisses, this granite is relatively undeformed. The age and composition of the granite implies that continental crust of the Bastar craton attained sufficient thickness to permit intracrustal melting at 3.6 Ga. Supplementary material: Representative major element, trace element and REE composition of the Dalli-Rajhara granite samples and a summary of SHRIMP U-Pb zircon data for the granite sample D-9 are available at http://www.geolsoc.org.uk/SUP18337.

TL;DR: In this article, the authors present a material, NaYbO2, that realizes the genuine spin-liquid state on the triangular lattice and benchmarks recent theoretical predictions on the relevant spin models.
Abstract: We present a candidate material, NaYbO2, that realizes the genuine spin-liquid state on the triangular lattice
and benchmarks recent theoretical predictions on the relevant spin models. Synchrotron x-ray diffraction and
neutron scattering exclude both structural disorder and crystal-electric-field randomness. Our thermodynamic
measurements, neutron diffraction, and muon spectroscopy coincidentally prove the absence of magnetic order
and persistent spin dynamics down to at least 70 mK. Continuous magnetic excitations first observed by
inelastic neutron scattering show a gapless feature and the low-energy spectral weight accumulating at the K
point of the Brillouin zone, in agreement with theoretical predictions for the spin-liquid phase of triangular
antiferromagnets. Such a gapless spin-liquid phase is further confirmed by our magnetic specific heat analysis
that reveals a departure from simple power-law behavior. Our work demonstrates that NaYbO2 practically gives
direct experimental access to the spin-liquid physics of triangular antiferromagnets.

TL;DR: In this article, the ideas of development and planning are complex and challenging to define and study, and there is a strong agreement that there is strong agreement on the strong agreement among tourism geographers.
Abstract: Development and planning have long been a focus of tourism geographers. Although the ideas of development and planning are complex and challenging to define and study, there is a strong agreement o...
