Because Florida is not located near any tectonic plate boundaries, earthquakes are very rare, but not totally unknown. In January 1879, a shock occurred near St. Augustine. There were reports of heavy shaking that knocked plaster from walls and articles from shelves. Similar effects were noted at Daytona Beach 50 miles (80 km
On the island of Malta, a variety of limestone called Globigerina limestone was, for a long time, the only building material available, and is still very frequently used on all types of buildings and sculptures. [105] Limestone can be processed into many various forms such as brick, cement, powdered/crushed, or as a filler. [102]
It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe , where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover ...
Carboniferous Limestone – Limestone deposited during the Dinantian Epoch of the Carboniferous Period; Coquina – Sedimentary rock that is composed mostly of fragments of shells; Coral rag – Limestone composed of ancient coral reef material; Chalk – Soft carbonate rock; Fossiliferous limestone – Limestone containing fossils
The top layer, the Upper Coralline Limestone (Maltese: Qawwi ta' Fuq), is the youngest formation of Messinian age (~7–5 million years old) and is around 140 m thick. [1] It is mainly present on the islands of Malta, Comino and in the east of Gozo. The Coralline Limestone is a hard, pale-grey limestone.
The Alifan limestone began to deposit after the Bonya limestone as Guam became almost entirely submerged, resembling an atoll. Montmorillinite clay and lignite fragments accumulated in the higher elevation swamps near the shore. The current limestone ridge on the Mount Alifan-Mount Lamlam ridge may represent the remnants of an atoll lagoon.
Miami Limestone (formerly Miami Oolite, orange on map) in relation to other formations in South Florida. The Miami Limestone, originally called Miami Oolite, is a geologic formation of limestone in southeastern Florida. Miami Limestone forms the Atlantic Coastal Ridge in southeastern Florida, near the coast in Palm Beach, Broward and Miami Dade ...
Brighton Beach, on the south coast of England, is a shingle beach that has been nourished with very large pebbles in an effort to withstand the erosion of the upper area of the beach. These large pebbles made the beach unwelcoming for pedestrians for a period of time until natural processes integrated the naturally occurring shingle into the ...
