Carbonate platform

A broad, shallow seafloor structure built mainly from carbonate sediment and organisms. Its shape and deposits reflect biological production, sediment transport, water depth, and subsidence.

Carbonate factory: The ecological and physical system that produces carbonate sediment in a marine setting. Its production rate supplies the material from which a platform grows.
Carbonate factory types: A classification of carbonate production systems by their organisms, environmental controls, and sediment output. Different factory types produce distinct platform geometries and sediment compositions.
Bahama Banks: A modern carbonate platform system in the western Atlantic, including shallow banks and surrounding deep water. Its clear-water banks expose modern platform sediment production and transport.
Sequence stratigraphy: The study of genetically related sedimentary strata bounded by surfaces formed during changes in accommodation and sediment supply. Its surfaces and stacking patterns help reconstruct platform response to sea-level cycles.
Carbonate sediment: Marine sediment composed chiefly of calcium carbonate minerals or skeletal fragments. Accumulated carbonate sediment builds platform interiors, margins, and slopes.
Reef: A rigid marine structure built by organisms, commonly supporting diverse communities and modifying water flow. Reefs can form platform margins and trap or redirect carbonate sediment.
Great Barrier Reef: The world's largest coral reef system, extending along Australia's northeastern coast. Its reef platform illustrates how a living margin interacts with a broad shallow shelf.
Carbonate reservoir: A porous and permeable carbonate rock body capable of storing and transmitting hydrocarbons or other fluids. Platform facies and later alteration create heterogeneous reservoir properties.
Carbonate ramp: A gently sloping carbonate depositional system lacking a sharply defined platform margin. It contrasts with platforms whose margins separate shallow tops from steep slopes.
Shoal: A shallow underwater area formed by sediment accumulation or bedrock, often affected by waves and currents. Shoals are common high-energy features across platform tops.
