Bran Point
Bran Point is a small headland on the Dorset coast in southern England, about halfway between the small villages of Ringstead to the east and Osmington Mills to the west. There is a picturesque cliff-top path between the two villages via Bran Point. The name derives from the brown colouring of the rock forming the cliffs of the headland, caused in part by residual oil deposits.Watson, D. F.; Hindle, A. D. and Farrimond P. (2000) "Organic geochemistry of petroleum seepages within the Jurassic Bencliff Grit, Osmington Mills, Dorset, UK" ''Petroleum Geoscience'' 6(4): pp. 289-297 The geology of the area is particularly interesting. The coastline in the area is formed from rocks and shingle with exposed cliffs behind. The Middle White Oolite of the Osmington Oolite more visible to the west has descended to beach level here. At the middle of the cliff, there is nodular rubble consisting of calcitized sponge spicules. Higher in the cliff are reddish brown beds containing ''Trigonia ...

Bran Point Dorset
Bran, also known as miller's bran, is the hard outer layers of cereal grain. It consists of the combined aleurone and pericarp. Corn (maize) bran also includes the pedicel (tip cap). Along with germ, it is an integral part of whole grains, and is often produced as a byproduct of milling in the production of refined grains. Bran is present in cereal grain, including rice, corn (maize), wheat, oats, barley, rye and millet. Bran is not the same as chaff, which is a coarser scaly material surrounding the grain but not forming part of the grain itself, and which is indigestible by humans. "chaff, which is indigestible for humans" Composition Bran is particularly rich in dietary fiber and essential fatty acids and contains significant quantities of starch, protein, vitamins, and dietary minerals. It is also a source of phytic acid, an antinutrient that prevents nutrient absorption. The high oil content of bran makes it subject to rancidification, one of the reasons that ...

Trigoniidae
Trigoniidae is a taxonomic family of saltwater clams, marine bivalve mollusks in the superfamily Trigonioidea. There is only one living genus, ''Neotrigonia'', but in the geological past this family was well represented, widespread and common. The shells of species in this family are morphologically unusual, with very elaborate hinge teeth, and the exterior of the shell is highly ornamented. Description The most striking feature of the Trigoniidae, which has attracted attention for centuries, is their external ornamentation. This is usually present as ribs or costae, or rows of aligned tubercles. The hinge teeth of the shell are unusually elaborate in structure. The living animal has no siphon. Origin This family originated from the Myophoriidae in the Triassic. The family underwent an explosion of diversity in the Jurassic, reaching a maximum of diversity in the Cretaceous, although most genera became extinct at the end of this period. Although they were abundant in the Mesoz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Nothe
White Nothe (meaning "White Nose") is a chalk headland on the English Channel coast at the eastern end of Ringstead Bay, east of Weymouth in Dorset, England. The area is well known for its geology and fossils. Its flanks are the result of prehistoric landslides and the inaccessible slopes of the undercliff provide a secluded wildlife habitat. A zigzag path up the cliff is believed to be one of the locations alluded to as a smuggler's path in the British children's book '' Moonfleet'' by J. Meade Falkner. Walking to the base of White Nothe along the shore from Ringstead Bay is possible, but it is cut off at high tide, so much care should be taken. At the top of the Smugglers path, a protruding nose shape comes out of the white cliff, giving the name to the area. The area is partly owned by the National Trust. From the top of White Nothe, to the east, the chalk headland of Bat's Head can be viewed. Walking east along a clifftop path below the summit of Chaldon Hill is possible ...

Geology Of Dorset
Dorset (or archaically, Dorsetshire) is a county in South West England on the English Channel coast. Covering an area of ; it borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The great variation in its landscape owes much to the underlying geology, which includes an almost unbroken sequence of rocks from 200 to 40 million years ago (Mya) and superficial deposits from 2 Mya to the present.Chaffey (pp.5–6) In general, the oldest rocks (Early Jurassic) appear in the far west of the county, with the most recent (Eocene) in the far east. Jurassic rocks also underlie the Blackmore Vale and comprise much of the coastal cliff in the west and south of the county; although younger Cretaceous rocks crown some of the highpoints in the west, they are mainly to be found in the centre and east of the county.Chaffey (p.6) Dorset's coastline is one of the most visited and studied coastlines in the world because it shows, along the c ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Spicule (sponge)
Spicules are structural elements found in most Sea sponge, sponges. The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. Sponge spicules are made of calcium carbonate or Silicon dioxide, silica. Large spicules visible to the naked eye are referred to as megascleres, while smaller, microscopic ones are termed microscleres. The composition, size, and shape of spicules are major characters in sponge systematics and Taxonomy (biology), taxonomy. Overview Sponges are a species-rich clade of the earliest-diverging (most Basal (phylogenetics), basal) animals. They are distributed globally, with diverse ecologies and functions, and a record spanning at least the entire Phanerozoic. Most sponges produce skeletons formed by spicules, structural elements that develop in a wide variety of sizes and three dimensional shapes. Among the four sub-clades of Porifera, three (Demospongiae, Hexactinelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slipping Clifftop, Bran Point - Geograph
Slipping is a technique used in boxing that is similar to bobbing. It is considered one of the four basic defensive strategies, along with blocking, holding, and clinching. It is performed by moving the head to either side so that the opponent's punches "slip" by the boxer. Slipping punches allows the fighter to recover quicker and counter punches faster than the opponent can reset into proper fighting stance. In boxing, timing is known to be a key factor in the outcome. Timing your slips correctly is essential in protecting yourself and saving energy. Slipping, if done incorrectly, can be dangerous as it exposes you to a counter-punch and an unbalanced stance. Which can lead to an opening for the opponent. Muhammad Ali is considered to be, pound for pound, one of the greatest fighters of all time. But what made him so lethal? Was it his power, speed, or technique of slipping punches? Many fighters and analysts will say it was his slipping capability. Image:slip1.jpg, Slip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcite
Calcite is a Carbonate minerals, carbonate mineral and the most stable Polymorphism (materials science), polymorph of calcium carbonate (CaCO3). It is a very common mineral, particularly as a component of limestone. Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on Scratch hardness, scratch hardness comparison. Large calcite crystals are used in optical equipment, and limestone composed mostly of calcite has numerous uses. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even less stable. Etymology Calcite is derived from the German ''Calcit'', a term from the 19th century that came from the Latin word for Lime (material), lime, ''calx'' (genitive calcis) with the suffix "-ite" used to name minerals. It is thus etymologically related to chalk. When applied by archaeology, archaeologists and stone trade pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oolite
Oolite or oölite (''egg stone'') is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. The name derives from the Ancient Greek word for egg (ᾠόν). Strictly, oolites consist of ooids of diameter 0.25–2 millimetres; rocks composed of ooids larger than 2 mm are called pisolites. The term ''oolith'' can refer to oolite or individual ooids. Composition Ooids are most commonly composed of calcium carbonate ( calcite or aragonite), but can be composed of phosphate, clays, chert, dolomite or iron minerals, including hematite. Dolomitic and chert ooids are most likely the result of the replacement of the original texture in limestone. Oolitic hematite occurs at Red Mountain near Birmingham, Alabama, along with oolitic limestone. They are usually formed in warm, supersaturated, shallow, highly agitated marine water intertidal environments, though some are formed in inland lakes. The mechanism of formation starts with a small fragment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
