Defined here as 'essentially in place calcareous deposits created by sessile organisms',
Organic Reefs are diverse and complex structures with a long geological history. Their …

Deposits produced by microbial growth and metabolism have been important components of
carbonate sediments since the Archaean. Geologically best known in seas and lakes …

Thrombolites and stromatolites are distinct types of microbial (cryptalgal) structures
characterized, respectively, by mesoscopic clotted and laminated internal fabrics. Although …

Early Triassic framestones were discovered in the interior of an isolated, marine carbonate
platform in the Nanpanjiang basin. The framestones occur in two horizons:(1) the lowermost …

Shallow-marine carbonate sediments occur in three settings: platforms, shelves and ramps.
The facies patterns and sequences in these settings are distinctive. However, one type of …

An almost 800 m thick stromatoporoid-coral series of the Kowala Formation (Narkiewicz et at
1990) forms the bulk of the epicontinental carbonate sequence in the Middle and Late …

Stromatolites are abundant in shallow marine sediments deposited before the evolution of
animals, but in the modern ocean they are restricted to locations where the activity of …

Using detailed petrographic analysis and a new method of handling similarity coefficients,
samples from over 30 Mid-Dinantian (Upper Tournaisian-Lower Viséan) carbonate buildups …

A variety of evidence can be used to estimate the absolute depth of the well‐established
depth gradient of Silurian onshore‐to‐offshore benthic assemblages (BA 1–5); this evidence …

Carbonate buildups in the Flinders Ranges of mid‐Early Cambrian age grew during a
period of high archaeocyath diversity and are of two types:(1) low‐energy, archaeocyath …
