These differences are reflected in the total harvest of coral products and also in the site and method of exploitation. While the construction industry is a major user of corals in the above-mentioned countries, it is clear that there is wide variation in the exploitation of specific coral products by different countries. In the offshore islands, it is estimated that over 10–24 tons of shells and corals are collected from the reefs per year in an activity that involves ten people collecting once or twice a week (Tomascik et al., 1997). Similarly, in West Sumatra branching and massive corals are extracted to sell as decorative materials for house walls.
Coral ‘stones’ extracted from areas such as the Gulf of Mannar, India, are used as building blocks or in road construction and as source material for house decorations. In India, corals (coral fragments or ‘challi’ rather than coral ‘stones’) are also used for the production of lime with lime kilns in the Tuticorin area of southern India, exporting lime all over the country to meet the demands of paper and sugar industries, leather tanning and bleaching, mortar production, and white wash paint. In Sri Lanka, corals are primarily used in the construction industry for production of mortar and plaster with subsidiary uses as lime in soil improvement and in the ceramic and cement industry. At Mafia Island, in Tanzania two forms of coral were extracted in the early to late twentieth century for both local and commercial construction (Dulvy et al., 1995) these were fossilized limestone and living reef coral. Early photographs taken by Agassiz in Malé in the Maldives in 1903 show houses constructed of coconut leaves and available timber, but by the mid-late tewntieth century construction of houses, boundary walls, groynes, and breakwaters with coral blocks was commonplace (Brown, 1997b). The use of coral rock as a construction material in many countries in the central Indian Ocean has had a long history, particularly in the building of mosques, temples, and shrines. These sea creatures from 240 million years ago.Coral mining has caused extensive degradation of reefs in a number of countries, which include India, Maldives, Sri Lanka, Tanzania, and the Philippines (Brown, 1997a). The types of fossils you can discover in this material include brachium pods, coral, snails, clams and gastropods brain wave and leaf coral.
The matrix cementing these fossils together is composed of the fragments of other fossils that broke up in the surf before the limestone solidified. This type of limestone is highly fossiliferous with calcium rich remains of ancient marine creatures trapped in the sediments of the banks or coral reefs where they once lived. Limestones are a sedimentary rock consisting mainly of calcium carbonate.
