TLDR
A trachytic volcanic ash layer is widely distributed across southwestern Russia, where it is found both in well-characterised archaeological contexts close to the Don River (the Paleolithic sites of Kostenki-Borschevo (51.4°N, 39.0°E), and in undisturbed geological contexts.About:

Tephrochronology and its application: A review
TL;DR: Tephrochronology is a unique stratigraphic method for linking, dating, and synchronizing geological, palaeoenvironmental, or archaeological sequences or events as discussed by the authors, which can be used for correlational purposes.

TL;DR: The findings reveal the timing of divergence of western Eurasians and East Asians to be more than 36,200 years ago and that European genomic structure today dates back to the Upper Paleolithic and derives from a metapopulation that at times stretched from Europe to central Asia.

A complete mtDNA genome of an early modern human from Kostenki, Russia
Johannes Krause,Adrian W. Briggs,Martin Kircher,Tomislav Maricic,Nicolas Zwyns,Anatoly P. Derevianko,Svante Pääbo +6 more
TL;DR: Fragmentation patterns and nucleotide misincorporations can be used to gauge authenticity of ancient DNA sequences and are used to determine a complete mtDNA sequence from a approximately 30,000-year-old EMH from the Kostenki 14 site in Russia.

Synchronisation of palaeoenvironmental records over the last 60,000 years, and an extended INTIMATE event stratigraphy to 48,000 b2k
Simon Blockley,Christine Lane,Mark Hardiman,Sune Olander Rasmussen,Inger K Seierstad,Jørgen Peder Steffensen,Anders Svensson,André F. Lotter,Chris S. M. Turney,Christopher Bronk Ramsey +9 more
TL;DR: The INTIMATE protocol for the correlation of marine ice core and terrestrial records is here updated, reflecting recent developments in palaeoclimate research as discussed by the authors, which has now extended its study period back to 60,000 years.
Journal ArticleDOI
The modern human colonization of western Eurasia: When and where?
TL;DR: The earliest phases of the Aurignacian complex seem to represent another modern wave of migrations, starting in the Levant area, and the expansion of this technocomplex throughout Europe completed the modern colonization of the continent.

The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.

Composition of the Earth
TL;DR: In this article, the authors reported that the resulting densities in the lower mantle are in good agreement with shock-wave measurements on rocks having FeO contents in the range 10 ± 2% by weight.

Radiocarbon calibration curve spanning 0 to 50,000 years BP based on paired 230 Th/ 234 U/ 238 U and 14 C dates on pristine corals

TL;DR: In this article, the authors presented high precision paired 230 Th/ 234 U/ 238 U and 14 C age determinations on pristine coral samples that enable them to extend the radiocarbon calibration curve from 12,000 to 50,000 years before present.

The thickness, volume and grainsize of tephra fall deposits
TL;DR: In this paper, an improved empirical method for the plotting of field data and the calculation of tephra fall volumes is presented, where two new quantitative parameters are proposed which describe the rates of thinning of the deposit (bt the thickness half distance) and the maximum clast size (bc the clast half distance).
