New constraints on the last aragonite–calcite sea transition from early Jurassic ooids

  author={Sara Vulpius and Wolfgang Kiessling},
Calcite and aragonite seas are commonly distinguished based on the prevailing primary mineralogy of ooids and carbonate cements over time. Secular oscillations of these seas are usually attributed to changes in ocean chemistry and paleoclimate. While the veracity of such oscillations has been verified by independent data and modeling approaches, the timing of the transition from one ocean state to the other remains poorly resolved. Here, the timing of the last aragonite–calcite sea transition… 
Short-term variation of ooid mineralogy in the Triassic-Jurassic boundary interval and its environmental implications: Evidence from the equatorial Ghalilah Formation, United Arab Emirates
Abstract In the Triassic-Jurassic (T-J) interval, only a few continuous carbonate sections have been reported, and detailed studies about ooids and their significance are scarce. This study focuses
Uranium isotope variations in a dolomitized Jurassic carbonate platform (Tithonian; Franconian Alb, Southern Germany)
Abstract The uranium (U) isotopic composition (δ238U) of limestones is increasingly used to quantitatively track changes in paleoredox conditions of the global ocean. However, many limestones have
Spatial and temporal facies evolution of a Lower Jurassic carbonate platform, NW Tethyan margin (Mallorca, Spain)
The variety of depositional facies of a Lower Jurassic carbonate platform has been investigated on the island of Mallorca along a transect comprising six stratigraphic profiles. Twenty-nine facies
Thrombolitic clots dominated by filamentous cyanobacteria and crusts of radio-fibrous calcite in the Furongian Changshan Formation, North China
Abstract As a variety of non-laminated microbial carbonate or calcified microbialite, thrombolites commonly comprise diffusely clotted micrites as their basic structural unit. The current study is

Evolutionary response by bivalves to changing Phanerozoic sea-water chemistry
Abstract Sedimentological evidence suggests that sea-water chemistryhas oscillated between ‘Aragonite’and ‘Calcite’seas during thecourse of Phanerozoic time. During ‘Calcite’sea periods arago-nite
Early Pliensbachian (Early Jurassic) C-isotope perturbation and the diffusion of the Lithiotis Fauna: Insights from the western Tethys
Abstract High-resolution carbonate carbon-isotope stratigraphy of Lower Jurassic marine shallow-water limestones are compared with the distribution of the Lithiotis Fauna on the Trento Platform
Chemical control of carbonate phases; implications from Upper Pennsylvanian calcite-aragonite ooids of southeastern Kansas
ABSTRACT Ooids in grainstones from the Spring Hill Member of the Pennsylvanian Plattsburg Limestone in southeastern Kansas were precipitated as both aragonite and calcite. Either phase predominated
Secular oscillations in the carbonate mineralogy of reef-building and sediment-producing organisms driven by tectonically forced shifts in seawater chemistry
The primary mineralogy of oolites and early marine carbonate cements led Sandberg [Nature 305 (1983), 19–22] to divide the Phanerozoic Eon into three intervals of `aragonite seas' and two intervals
Shell mineralogical trends in epifaunal Mesozoic bivalves and their relationship to seawater chemistry and atmospheric carbon dioxide concentration
The Late Triassic-Early Jurassic change from aragonite- to calcite-facilitating conditions in the oceans, which was caused by a decrease of the Mg2+/Ca2+ ratio of seawater in combination with an
A dinosaur tracksite in an early Liassic tidal flat in northern Italy; paleoenvironmental reconstruction from sedimentology and geochemistry
Lateral and vertical sedimentological, ichnological, and geochemical characteristics of a tracksite at Lavini di Marco (Southern Alps, Northern Italy) allowed for the reconstruction of a semi-arid,
Calcite and aragonite seas and the de novo acquisition of carbonate skeletons.
The results suggest that calcite and aragonite seas do have a strong influence on carbonate skeletal mineralogy, however, this appears to be true only at the time mineralized skeletons first evolve.
Aragonite-calcite seas—Quantifying the gray area
Oscillations between the dominance of aragonite and calcite in abiotic marine CaCO3 precipitates throughout Earth history are closely coupled with the evolution of Earth’s seawater composition and
Constituent analysis of an Ordovician limestone from Sweden
Quantitative data on the carbonate constituents of the early Viruan (‘Middle Ordovician’) Segerstad Limestone of Sweden are given, based on modal ana lyses of thin sections. The grain size of the

SummaryThe Rhaetian facies of the Lombardian Basin (Southern Alps) are syn-rift deposits characterized by a high rate of deposition, considerable variation of thickness and a cyclic deposition of
