![]() ![]() Most modern ooids are composed of mineral aragonite. However, the exact formation mechanisms are still unresolved 4. It is believed that ooid formation is generally abiogenic process. Warm water is needed to lower the carbon dioxide content in water (higher temperature reduces the ability of water to keep gases dissolved) and thereby enhance the precipitation of calcium carbonate. This is also the reason why ooids are so well-polished. Ooids are kept moving by waves which enables accretion to occur on all sides. Ooids in these places form a distinct type of sand - ooid sand. ![]() Most ooids are marine, forming in shallow (less than 10 m, preferably even less than 2 meters), warm, and wave-agitated water such as the Persian Gulf and the Bahama Platform. Ooids may be spherical but some are elongated, depending on the shape of nucleus. Ooids usually possess a clearly developed growth banding. The terms “oolite” and “ooid” are derived from the Greek word for fish roe ( oon) which ooids resemble 4. Oolite forms when ooids like this get cemented together. Ooid sand from Antelope Island, The Great Salt Lake. Larger grains with similar genesis are pisoids (pisoliths). The term “ooid” is applied to grains less than 2 mm in diameter. Nucleus is usually either mineral grain or biogenic fragment. Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus. Most oolites are limestones - ooids are made of calcium carbonate (minerals aragonite or calcite). Miami is the epicenter of the most contemporary art scene in the state, and the construction boom that seems to last decades, will always be built upon oolite, beyond the foundations and onto the most recognizable features of buildings old and new.Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. The story of oolite has become an artistic opportunity with results that celebrate the bedrock of Florida and the remarkable diversity of materials, artistic and structural, that have come together over the years. The shapes of the stones, oval and smooth, are the most basic units to appear in much of the work in the exhibition, especially as they are cemented into our familiar keystone or coral rock. When presented with the idea of using oolite as the focus of an exhibition, each one considered the stone from a different perspective related to their own memories and practice and to a new historical and ecological view of their surroundings that they may have taken for granted, but now merit artistic consideration. ![]() This collective exhibition includes the work of an eclectic group of 12 artists working in South Florida, upon a foundation of oolite. For artists in South Florida looking for inspiration in their own distinctive environment, it is ecological, geological, available, and always interesting. It is a distinctive feature of building facades, stairways, and patio flooring that ages to reveal a natural patina formed over the vestiges of fossils, coral, shells and small bits of marine life. It is a coral limestone (also called keystone) consisting of the calcareous skeletons of corals often cemented by calcium carbonate, with a few spherical inclusions (oolites). In Florida, coral rock is a variation of oolite and our most familiar building material and the foundation of our landscape. The name derives from the Ancient Greek word for egg. According to the dictionary, oolite or oölite (egg stone) is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. South Florida is mainly composed of oolitic limestone, which was formed when shallow seas covered the area between periods of glaciation and deposits of limestone were consolidated and eroded during later exposure above the ocean surface.
