Oolites
Petroleum is the name given to fluid hydrocarbons, both the gases and the liquid crude oil. It is commonly noted that petroleum occurs almost exclusively within sedimentary rocks (sandstones, limestones, and claystones). Petroleum is seldom found in igneous or metamorphic rocks. Thus petroleum geology is very largely concerned with the study of ...The Noix Oolite is typical of calcareous oolites deposited under agi tated, shallow-water, normal-marine conditions. The mechanism of formation and the depositional environment of ferruginous oolites (oolitic ironstones) such as the Neda Formation is, in general, controversial. Proposed origins range94 „Robert V. Burne et al." 1. Introduction. Oolites . are limestones composed of spherical, concentrically laminated carbonate grains (ooids) generally up to about two millimetres in diameter.

Precipitation of calcium carbonate is widespread in microbial communities (biofilms, microbial mats, etc.) and plays an important role in the nucleation and formation of stromatolites, onkolites and oolites.Oolite. Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.Devonian iron oolites were also formed worldwide during a negative Sr isotope excursion (Fig. 6).
