Pandanus Problematicus
''Pandanus candelabrum'', also known as the chandelier tree, is a species of screw palm found in tropical Africa, notably Liberia. It only grows on kimberlite outcroppings, making it a potentially useful indicator for diamond prospecting. References External links * candelabrum A candelabra (plural candelabras) or candelabrum (plural candelabra or candelabrums) is a candle holder with multiple arms.

Palisot De Beauvois
Ambroise Marie François Joseph Palisot, Baron de Beauvois (27 July 1752, in Arras – 21 January 1820, in Paris) was a French naturalist and zoologist. Palisot collected insects in Oware, Benin, Saint Domingue, and the United States, from 1786 to 1797. Trained as a botanist, Palisot published a significant entomological paper entitled, "Insectes Receuillis en Afrique et en Amerique". Together with Frederick Valentine Melsheimer, he was one of the first entomologists to collect and describe American insects. He described many common insects and suggested an ordinal classification of insects. He described many Scarabaeidae as well as illustrating them for the first time. The study included 39 '' Scarabaeus'' species, 17 '' Copris'' species, 7 '' Trox'' species, 4 '' Cetonia'' and 4 '' Trichius'' species. Familiar beetles such as '' Canthon viridis'', '' Macrodactylus angustatus'' and '' Osmoderma scabra'' were first described by him. Many of the specimens that were labelled fro ...

Pandanus
''Pandanus'' is a genus of monocots with some 750 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm, and screw pine. They are classified in the order Pandanales, family Pandanaceae. Description Often called pandanus palms, these plants are not closely related to palm trees. The species vary in size from small shrubs less than tall, to medium-sized trees tall, typically with a broad canopy, heavy fruit, and moderate growth rate. The trunk is stout, wide-branching, and ringed with many leaf scars. Mature plants can have branches. Depending on the species, the trunk can be smooth, rough, or warty. The roots form a pyramidal tract to hold the trunk. They commonly have many thick stilt roots near the base, which provide support as the tree grows top-heavy with leaves, fruit, and branches. These roots are adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberia
Liberia (), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to Liberia–Sierra Leone border, its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5 million and covers an area of . English is the official language, but over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The country's capital and largest city is Monrovia. Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born black people who faced social and legal oppression in the U.S., along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimberlite
Kimberlite is an igneous rock and a rare variant of peridotite. It is most commonly known to be the main host matrix for diamonds. It is named after the town of Kimberley in South Africa, where the discovery of an diamond called the Star of South Africa in 1869 spawned a diamond rush and the digging of the open-pit mine called the Big Hole. Previously, the term kimberlite has been applied to olivine lamproites as Kimberlite II, however this has been in error. Kimberlite occurs in the Earth's crust in vertical structures known as kimberlite pipes, as well as igneous dykes. Kimberlite also occurs as horizontal sills. Kimberlite pipes are the most important source of mined diamonds today. The consensus on kimberlites is that they are formed deep within the mantle. Formation occurs at depths between , potentially from anomalously enriched exotic mantle compositions, and they are erupted rapidly and violently, often with considerable carbon dioxide and other volatile componen ...

Geobotanical Prospecting
Geobotanical prospecting refers to prospecting based on indicator plants like metallophytes and the analysis of vegetation. For example, the Viscaria Mine in Sweden was named after the plant '' Silene suecica'' (syn. '' Viscaria alpina'') that was used by prospecters to discover the ore deposits. A "most faithful" indicator plant is '' Ocimum centraliafricanum'', the "copper plant" or "copper flower" formerly known as ''Becium homblei'', found only on copper (and nickel) containing soils in central to southern Africa. In 2015, Stephen E. Haggerty identified '' Pandanus candelabrum'' as a botanical indicator for kimberlite pipes, a source of mined diamonds. The technique has been used in China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ... since in the 5th century BC. Peop ...
