A transdisciplinary and community-driven database to unravel subduction zone initiation

Subduction zones are pivotal for the recycling of Earth’s outer layer into its interior. However, the conditions under which new subduction zones initiate are enigmatic. Here, we constructed a transdisciplinary database featuring detailed analysis of more than a dozen documented subduction zone initiation events from the last hundred million years. Our initial findings reveal that horizontally forced subduction zone initiation is dominant over the last 100 Ma, and that most initiation events are proximal to pre-existing subduction zones. The SZI Database is expandable to facilitate access to the most current understanding of subduction zone initiation as research progresses, providing a community platform that establishes a common language to sharpen discussion across the Earth Science community

ANALYSIS OF THE INTERACTION OF LIPID METABOLISM ALLELES IN DYSLIPIDEMIA

Parameters of lipid metabolism in the spectrum of blood serum are the most commonly used indicators in clinical practice. Their disturbances (dyslipidemia) are: elevated levels of total cholesterol and triglycerides, as well as changes of other parameters resulting from aberrations in lipoprotein synthesis, transport and cleavage. The clinical significance of metabolic disorders covered by the term dyslipidemia is associated primarily with high risks of cardiovascular diseases, diabetes mellitus type 2, and obesity. Associations of certain SNPs (G-2548A in the promoter region of the leptin gene (LEP), A223G in exon 4 of the leptin receptor gene (LEPR), T495G in intron 8 in the lipoprotein lipase gene (LPL), and C34G in exon 8 of a nuclear receptor (PPARG)) with disturbed lipid metabolism have been investigated, and their cumulative contribution to the development of dyslipidemia is demonstrated

Record of massive upwellings from the Pacific large low shear velocity province

Large igneous provinces, as the surface expression of deep mantle processes, play a key role in the evolution of the planet. Here we analyse the geochemical record and timing of the Pacific Ocean Large Igneous Provinces and preserved accreted terranes to reconstruct the history of pulses of mantle plume upwellings and their relation with a deep-rooted source like the Pacific large low-shear velocity Province during the Mid-Jurassic to Upper Cretaceous. Petrological modelling and geochemical data suggest the need of interaction between these deep-rooted upwellings and mid-ocean ridges in pulses separated by ∼10-20 Ma, to generate the massive volumes of melt preserved today as oceanic plateaus. These pulses impacted the marine biota resulting in episodes of anoxia and mass extinctions shortly after their eruption.National Science Foundation/[EAR-1019327]/NSF/Estados UnidosMinisterio de Ciencia, Tecnología y Telecomunicaciones/[MICITT-STCI-OF-274-2013]/Micitt/Costa RicaNational Science Foundation/[EAR-12019033]/NSF/Estados UnidosUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Básicas::Centro de Investigación en Ciencias Geológicas (CICG
