Journal ArticleDOI
Calcium isotope record of Phanerozoic oceans: Implications for chemical evolution of seawater and its causative mechanisms
Juraj Farkas,Florian Böhm,Klaus Wallmann,John Blenkinsop,Anton Eisenhauer,Robert van Geldern,Axel Munnecke,Silke Voigt,Ján Veizer +8 more
TL;DR: This article used brachiopods of Ordovician to Cretaceous age, complemented by published data from belemnites and planktonic foraminifera, to reconstruct the evolution of calcium isotope composition of seawater over the Phanerozoic.
Journal ArticleDOI
Stable calcium isotopic compositions of Hawaiian shield lavas: Evidence for recycling of ancient marine carbonates into the mantle
TL;DR: In this paper, high-precision 44Ca/40Ca measurements of Hawaiian shield stage tholeiites are reported, showing that up to 40% of the Ca budget and 65% of Sr budget in some Hawaiian (Makapuu-stage Koolau) lavas are derived from recycled carbonates.
Journal ArticleDOI
Calcium isotopic fractionation between clinopyroxene and orthopyroxene from mantle peridotites
TL;DR: The first observation of Ca isotopic fractionation between co-existing clinopyroxene and orthopyroxenes from Kilbourne Hole and San Carlos mantle peridotites was reported in this article.
Journal ArticleDOI
Chromium isotope variations (δ53/52Cr) in mantle-derived sources and their weathering products: Implications for environmental studies and the evolution of δ53/52Cr in the Earth’s mantle over geologic time
Juraj Farkas,Vladislav Chrastný,Martin Novak,Eva Čadková,Jan Pašava,Ramananda Chakrabarti,Ramananda Chakrabarti,Stein B. Jacobsen,Lukáš Ackerman,Thomas D. Bullen +9 more
TL;DR: In this paper, a set of globally distributed and stratigraphically constrained chromites (FeMgCr2O4, n = 30) collected from various locations in Europe, Asia, Africa and South America were used to further constrain the isotope composition of the Earth's mantle Cr inventory and its possible variation during geological history.
Journal ArticleDOI
Evolution of the oceanic calcium cycle during the late Mesozoic: Evidence from δ44/40Ca of marine skeletal carbonates
TL;DR: In this article, the Ca isotope compositions of 37 late Mesozoic skeletal carbonates, belemnites and brachiopods from the Tethyan realm were analyzed by thermal (TIMS) and plasma (MC-ICP-MS) ionization mass spectrometry.
