Mar 01 2008 0183 32 The benthic automicrite factory predominated through much of the Triassic producing not only mud-mounds on middle ramps and basin floors but also progradation of carbonate slopes into sediment-starved anoxic basins Russo et al 1998 as noted above Such margin deposits were steep commonly with constant thickness and steepness which...
The Carbonate Factory Course Details Not all carbonates are the same Not only do carbonate producers change with water depth temperature and latitude they have also changed over time Modern coral though impressive were not the dominant producers through geologic time Before tackling a carbonate platform it is vital to understand who the...
Jan 22 2021 0183 32 The Cenozoic era 66 to 0 million years is marked by long-term aberrations in carbon cycling and large climatic shifts some of which challenge the current understanding of carbon cycle dynamics Here we investigate possible mechanisms responsible for the observed long-term trends by using a novel approach that features a full-fledged ocean carbonate chemistry model Using a...
This course provides an in-depth understanding of the controls on the development of carbonate successions using a process-product approach The dominant influences of biota and sea level change on the facies architecture and reservoir characteristics of ramp and reef systems are examined...

The Bahama Banks is an excellent laboratory of a subtidal carbonate factory Subtidal environments have Normal marine waters with a narrow range of salinity Well oxygenated Support a wide range of organisms hence diverse fauna and bioturbation Carbonate can be formed by...
Dec 03 2011 0183 32 Origin of Carbonate Rocks In geology carbonates are a class of sedimentary rocks compose primarily of carbonate minerals Two major types are limestone which is composed of calcite or aragonite different crystalline forms of CaCO3 and dolostone which is composed of the mineral dolomite CaMg CO3 2...
Jan 11 2021 0183 32 This journal provides a forum for the exchanges of ideas on all aspects of carbonate and evaporite geology In addition to professional papers Carbonates and Evaporites features reports from meetings news from societies letters to the editor and a regular book review section...
Carbonate Rocks The carbonate rocks make up 10 to 15 of sedimentary rocks They largely consist of two types of rocks Limestones which are composed mostly of calcite CaCO 3 or high Mg calcite Ca Mg CO 3 and Dolostones which are composed mostly of dolomite CaMg CO 3 2 Because carbonate minerals in general are soluble in slightly acidic waters they often have high porosity and...
Carbonate rocks are made of particles composed gt 50 carbonate minerals embedded in a cement Most carbonate rocks result from the accumulation of bioclasts created by calcareous organisms Therefore carbonate rocks originate in area favoring biological activity ie in shallow and warm seas in areas with little to no siliciclastic input...

Oct 26 2000 0183 32 Carbonate rock names limestones and dolomites consist of a conjunction of two names one describing the ALLOCHEMS the large pieces the other describing the INTERSTITIAL MATERIAL Allochems are equivalent to gravel sand lithics or feldspars in the siliciclastics Interstitial material is equivalent to clay or cements in clastics...
Overall the carbonate factory immediately after the PTME shows similarities to that of the Precambrian and accordingly a benthic-automicrite carbonate factory model was proposed to provide...
Here we recalculate carbonate production on Great Bahama Bank west and northwest of Andros Island using Broecker and Takahashi s 1966 pioneering geochemical study In the calculations residence time and depth are used to calculate yearly carbonate production based on equilibrium thermodynamics of CaCO 3 loss from water over the banks...

The term carbonate factory was introduced to define the narrow depth zone where tropical reefs and detrital carbonates are produced eg Tucker and Wright 1990 James and Kendall 1992 Reading and Levell 1996 Based on the carbonate factory principle Schlager proposed a threefold subdivision of the benthic carbonate production systems with the planktonic carbonate factory as a...
Carbonate factory turnovers are the integrated result of climatic oceanographic and biological controls Sedimentological geochemical and palaeontological data from core XK-1 drilled in the Xisha Islands South China Sea reveal that photozoan to heterozoan carbonate factory turnovers during the Early and Middle Miocene in isolated carbonate platforms were mainly caused by changes in the...

The carbonate factory was defined by Schlager 2005 as the shallow illuminated seafloor where sediment particles are generated within the sea water from the crystallization of skeletal remains or precipitation out of sea water Many consider the carbonate factory to be the core of carbonate deposition throughout the world...

The rationale for introducing the concept of carbonate factories is based on the recognition of geologically and geographically recurring facies and associated biotic and abiotic production systems An obvious advantage of the concept is to focus attention on the dominant environmental and biochemical controls on carbonate precipitation in...
