Luxulyanite
Luxullianite (also known as luxulyanite or luxulianite) is a rare type of porphyritic tournalinized granite, notable for the presence of clusters of radially-arranged acicular tourmaline crystals enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica, and cassiterite. The name originates from the village of Luxulyan in Cornwall, United Kingdom, where this type of granite is found. An example may be seen in the Duke of Wellington's tomb in St Paul's Cathedral in London. Some luxullianite is also used in the Porphyry Hall of the Place House in Fowey Fowey ( ; , meaning ''beech trees'') is a port town and civil parishes in England, civil parish at the mouth of the River Fowey in south Cornwall, England, United Kingdom.

Cassiterite
Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite was the chief tin ore throughout ancient history and remains the most important source of tin today. Occurrence Most sources of cassiterite today are found in alluvial or placer deposits containing the weathering-resistant grains. The best sources of primary cassiterite are found in the tin mines of Bolivia, where it is found in crystallised hydrothermal veins. Rwanda has a nascent cassiterite mining industry. Fighting over cassiterite deposits (particularly in Walikale) is a major cause of the conflict waged in eastern parts of the Democratic Republic of the Congo. This has led to cassiterite being considered a conflict mineral. Cassiterite is a widespread minor constituent of igneous rocks. The Bolivian veins and the 4500 year old workings of Cornwall and Devon, England, are concentrate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fowey
Fowey ( ; , meaning ''beech trees'') is a port town and civil parishes in England, civil parish at the mouth of the River Fowey in south Cornwall, England, United Kingdom. The town has been in existence since well before the Norman invasion, with the local church first established some time in the 7th century; the estuary of the River Fowey forms a natural harbour which enabled the town to become an important trading centre. Privateers also made use of the sheltered harbourage. The Lostwithiel and Fowey Railway brought China clay here for export. History Early history The Domesday Book survey at the end of the 11th century records manors at Penventinue and Trenant, and a priory was soon established nearby at Tywardreath. the prior granted a charter to people living in Fowey itself. This medieval town ran from a north gate near Boddinick Passage to a south gate at what is now Lostwithiel Street; the town extended a little way up the hillside and was bounded on the other side b ...

Place House
Place is a Fortified House and Grade I listed building located in Fowey, Cornwall, England. Home of the Treffry family since the thirteenth century, the original structure was a fifteenth-century tower, which was defended against the French in 1457 by Elizabeth Treffry. It was strengthened soon afterwards, largely rebuilt in the sixteenth century and remodelled in the nineteenth century, the east front dating mostly from 1817 to 1845. The house is not open to the public except on special occasions. History Place is the seat of the Treffry family, and played an important role in defending the town against the marauding French. The tower is from the fifteenth century and it was here, in 1457, that Elizabeth Treffry led the defence. The tower was strengthened and largely rebuilt in the early sixteenth century. In 1731 John Treffry left the house, on his death, to his nephew William Toller, who took on the surname of Treffry — in addition to his own — by Act of Parliament. In ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into fragile elastic plates. This characteristic is described as ''perfect basal cleavage''. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, and fillers, especially in parts for automobiles, roofing, and in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost". Properties and structure The mica group comprises 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are translucent to opa ...
