Trenton and Black River Carbonates in the Union Furnace Area
southeast Subjacent Cambrian carbonates, the Lower to Middle Ordovician Beekmantown Group, and the Middle Ordovician Loysburg Formation were deposited on a rimmed carbonate shelf, with restricted circulation and wave action, on which vast peritidal and shallow water carbonate facies flourished (Goldhammer and others, 1987; Faill, 1999)
Authigenic formation of Ca–Mg carbonates in the shallow
of Ca–Mg carbonates in Lake Neusiedl 2 Study area Lake Neusiedl, situated at the Austrian–Hungarian border, is the largest endorheic lake in western Europe It is lo-cated in the Little Hungarian Plain, a transition zone be-tween the Eastern Alps and the Pannonian Basin in central
Microbe–mineral interactions: early carbonate precipitation
Keywords Bahamas, carbonates, lacustrine, microbialite, sulphate reduction INTRODUCTION Microbial communities and the mineral world are dancing a ‘geobiological tango’ (Nealson & Ghiorse, 2001) Environmental conditions im-pact on the bacterial community, which in turn alters the environment through its metabolic activities
Lacustrine and palustrine carbonate petrography an overview
carbonates (needles, subspherical or cylindrical vertical nodules, carbonate coatings, early and late diagenetic crys- tals, Microcodium ) Carbonate palustrine features can be associated with
Multi-proxies analysis of the evolution of the early
sediments are dominated by heterozoan carbonates According to Pittet et al (2002) and Burla et al (2008), an increase in terrigenous run-off may have increased nutrient supply, which favoured fast-growing organisms with asexual reproduction (Birkeland, 1988) as is proposed by Vilas et al (1995) for large foraminifera such as orbitolinids
