History Of Madagascar
The history of Madagascar is distinguished clearly by the early isolation of the landmass from the ancient supercontinent containing Africa and India, and by the island's late colonization by human settlers from the Sunda islands (Malay Archipelago) and from East Africa. These two factors facilitated the evolution and survival of thousands of endemic plant and animal species, some of which have gone extinct or are currently threatened with extinction. Trade in the Indian Ocean at the time of first colonization of Madagascar was dominated by Indonesian ships, probably of Borobudur ship and K'un-lun po types. Over the past two thousand years the island has received waves of settlers of diverse origins including Austronesian, Bantu, Arab, South Asian, Chinese, and European. The majority of the population of Madagascar today is a mixture of Austronesian and Bantu settlers. Despite popular belief, there has been no genetic input from Arabs or Indians, although one tribe, the Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Londonite
The borate minerals are minerals which contain a borate anion group. The borate (BO3) units may be polymerised similar to the SiO4 unit of the silicate mineral class. This results in B2O5, B3O6, B2O4 anions as well as more complex structures which include hydroxide or halogen anions.Klein, Cornelis and Cornelius Hurlbut, Jr., ''Manual of Mineralogy'', Wiley, 20th ed., 1985 pp. 343 - 347 The (O,OH)4sup>− anion exists as well. Many borate minerals, such as borax, colemanite, and ulexite, are salts: soft, readily soluble, and found in evaporite contexts. However, some, such as boracite, are hard and resistant to weathering, more similar to the silicates. There are over 100 different borate minerals.

Liddicoatite
Fluor-liddicoatite is a rare member of the tourmaline group of minerals, elbaite subgroup, and the theoretical calcium endmember of the elbaite-fluor-liddicoatite series; the pure end-member has not yet been found in nature. Fluor-liddicoatite is indistinguishable from elbaite by X-ray diffraction techniques. It forms a series with elbaite and probably also with olenite. Liddiocoatite is currently a non-approved mineral name, but Aurisicchio et al. (1999) and Breaks et al. (2008) found OH-dominant species. Formulae are * Fluor-liddicoatite Ca(Li2Al)Al6(BO3)3Si6O18(OH)3F * Elbaite Na(Al1.5Li1.5)Al6(BO3)3Si6O18(OH)4 * Olenite NaAl9B3Si6O27O3(OH) Fluor-liddicoatite was named in 1977 after Richard T. Liddicoat (1918–2002) gemmologist and president of the Gemological Institute of America, who is well known for introducing the GIA diamond grading system in 1953. Unit cell Fluor-liddicoatite belongs to the trigonal crystal system, class 3 m, space group R 3m. It has a rhombohedr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrocolumbite
Columbite, also called niobite, niobite-tantalite and columbate [], is a black mineral group that is an ore of niobium. It has a submetallic Lustre (mineralogy), luster and a high density and is a niobate of iron and manganese. This mineral group was first found in Haddam, Connecticut, in the United States. It forms a series with the tantalum-dominant analogue ferrotantalite and one with the manganese-dominant analogue manganocolumbite. The iron-rich member of the columbite group is ferrocolumbite. Some tin and tungsten may be present in the mineral. Yttrocolumbite is the yttrium-rich columbite with the formula . It is a radioactive mineral found in Mozambique. Columbite has the same composition and crystal symmetry ( orthorhombic) as tantalite. In fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite or coltan in many mineral guides. However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
