Microfacies of Carbonate Rocks: Analysis, Interpretation and Application
Microfossils within and on ooids. A - Ooids offering a hard substrate for encrusting organisms. In areas dominated by mobile calcareous sands, ooids and bioclasts often are the only substrates available for encrusting organisms, particularly ...

A Color Guide to the Petrography of Carbonate Rocks: Grains, ...
Definitions: Ooid (oolith) - a spherical to ellipsoidal grain, 0.25 to 2.00 mm in diameter, with a nucleus covered by one or more precipitated concentric coatings (cortical layers) with radial and/or concentric orientation of constituent crystals.
Peter A. Scholle, Dana S. Ulmer-Scholle, 2003
3.2.5 Coated Grains: Ooids and Oncoids Included here are a range of small (<1 mm-30 cm) unattached biotic and abiotic forms of travertine. Coated grains consist of a nucleus upon which a cortex of carbonate is accreted in an approximately ...

Geochemistry of Sedimentary Carbonates - Strona 234
The only investigator recently to argue forcibly in favor of the algal formation of ooids is Fabricius (1977). He observed that algae can make the aragonite "rod and granule" structure found in grapestones. He hypothesized that this was ...
J.W. Morse, F.T. Mackenzie, 1990

Green Marine Clays: Oolitic Ironstone Facies, Verdine Facies, ...
For this author, the formation of green and red ooids close together or of alternating green and red cortices within one ooid, suggest an ooid accretion mechanism that was periodically influenced by more oxidizing conditions at the sediment ...

Carbonate Sediments and Rocks Under the Microscope: A Colour Atlas
3–5 show a grain mount of Recent ooids from the Arabian Gulf. Two ooids have detrital quartz nuclei, recognisable by the low relief in the photograph taken with plane-polarised light (3) and the firstorder grey interference colours visible under ...
Anthony Adams, Ian R. MacKenzie, 1998

Coated Grains - Strona 138
tions of facies other than ooid grainstone indicate that the shoal is compound and not the product of a single depositional environment or process. The basic facies suite is a fringe of ooid grainstone bordering a shoal composed of opposing ...

A Method of Obtaining Climatic Parameters from Leaf Assemblages
Large spar crystals occur with the larger ooids. Smaller ooids commonly occur in microspar cement. Lamination is accentuated by the presence of spar associated with coarse basal layers and microspar associated with the finer upper layers.

Origin of Carbonate Rocks - Strona 169
Marine ooid sands are unique to the warm‐water photozoan depositional system (see Chapter 10). Although common in the geological record, they are not abundant in the modern ocean. Most Holocene deposits occur in the Caribbean Sea, ...
Noel P. James, Brian Jones, 2015

Sea-level research: a manual for the collection and evaluation of ...
THE FORMATION OF OOIDS The environmental controls on ooid growth may not be sufficiently stringent to allow a precise interpretation of the ooid's depth of origin. Several factors may be important to the growth process, including the ...
