Rockhounding
Amateur geology or rock collecting (also referred to as rockhounding in the United States and Canada) is the non-professional study and hobby of collecting rocks and minerals or fossil specimens from the natural environment.Sinkankas, John. Mineralogy For Amateurs. New York: Van Nostrand Reinhold, 1964. Print. In Australia, New Zealand and Cornwall, the amateur geologists call this activity fossicking. The first amateur geologists were prospectors looking for valuable minerals and gemstones for commercial purposes. Eventually, however, more people have been drawn to amateur geology for recreational purposes, mainly for the beauty that rocks and minerals provide. Accessibility One reason for the rise in popularity of amateur geology is that a collection can begin by simply picking up a rock. There are people who have formed clubs and groups that search for specimens and compare them with collections from other groups as a hobby. Information on such groups can be found at libra ...

Kunzite Nouristan
Spodumene is a pyroxene mineral consisting of lithium aluminium Silicate minerals#Inosilicates, inosilicate, lithium, Lialuminum, Al(silicon, Sioxygen, O3)2, and is a commercially important source of lithium. It occurs as colorless to yellowish, purplish, or lilac kunzite (see below), or alternatively yellowish-green or emerald-green hiddenite; it takes the form of prismatic crystals, often of great size. Single crystals of in size are reported from the Black Hills of South Dakota, United States. The naturally occurring low-temperature form α-spodumene is in the monoclinic system, and the high-temperature β-spodumene crystallizes in the tetragonal system. α-Spodumene converts to β-spodumene at temperatures above 900 °C. Typically crystals are heavily striated along the principal axis. Crystal faces are often etched and pitted with triangular markings. Discovery and occurrence Spodumene was first described in 1800 for an occurrence in the type locality (geology), type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrology
Petrology () is the branch of geology that studies rocks, their mineralogy, composition, texture, structure and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because both make heavy use of chemistry, chemical methods, and phase diagrams. Sedimentary petrology is commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock. Modern sedimentary petrology is making increasing use of chemistry. Background Lithology was once approximately synonymous with petrography, but in current usage, lithology focuses on macroscopic hand-sample or outcrop-scale description of rocks while petrography is the speciality that deals with microscopic details. In the petroleum industry, lithology, or more specifically mud logging, is the graphic representation of geological formations being drilled through and drawn ...

Mineral Collecting
Mineral collecting is the hobby of systematically collecting, identifying and displaying mineral specimens. Mineral collecting can also be a part of the profession of mineralogy and allied geologic specialties. Individual collectors often specialize in certain areas, for example collecting samples of several varieties of the mineral calcite from locations spread throughout a region or the world, or of minerals found in pegmatites. History Generally considered the "father of mineralogy", Georgius Agricola (1494–1555) was also an avid mineral collector. He wrote several books, including two of enduring significance: '' De Re Metallica'', an early treatise on mining, and '' De Natura Fossilium'', the first (1546) modern textbook of mineralogy. Another famous 16th century mineral collector was Holy Roman Emperor Rudolf II (1552–1612). He built a large mineral collection while employing Anselmus de Boodt (–1634), his court physician and another avid mineral collector, to ex ...

George Frederick Kunz
George Frederick Kunz (September 29, 1856 – June 29, 1932) was an American mineralogist and mineral collector. Biography Kunz was born in New York City, USA, and began an interest in minerals at a very young age. By his teens, he had amassed a collection of over four thousand items, which he sold for four hundred dollars to the University of Minnesota. Kunz attended Cooper Union but did not finish and did not attend college. Nonetheless, he taught himself mineralogy from books and field research. This expertise landed him a job with Tiffany & Co., and his knowledge and enthusiasm propelled him into a vice presidency by the time he was 23. He gained much notoriety for identifying a new gem variety of the mineral spodumene which was named "Kunzite" in his honor. He also supervised the cutting of the very large stone that became the Tiffany Yellow Diamond. He headed up the US mining and mineralogical exhibits at the international expositions in Paris (1889), Chicago (18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Ruskin
John Ruskin (8 February 1819 20 January 1900) was an English polymath a writer, lecturer, art historian, art critic, draughtsman and philanthropist of the Victorian era. He wrote on subjects as varied as art, architecture, Critique of political economy, political economy, education, museology, geology, botany, ornithology, literature, history, and myth. Ruskin's writing styles and literary forms were equally varied. He wrote essays and treatises, poetry and lectures, travel guides and manuals, letters and even The King of the Golden River, a fairy tale. He also made detailed sketches and paintings of rocks, plants, birds, landscapes, architectural structures and ornamentation. The elaborate style that characterised his earliest writing on art gave way in time to plainer language designed to communicate his ideas more effectively. In all of his writing, he emphasised the connections between nature, art and society. Ruskin was hugely influential in the latter half of the 19th c ...

Goethite
Goethite (, ) is a mineral of the diaspore group, consisting of iron(III) oxide-hydroxide, specifically the α- polymorph. It is found in soil and other low-temperature environments such as sediment. Goethite has been well known since ancient times for its use as a pigment (brown ochre). Evidence has been found of its use in paint pigment samples taken from the caves of Lascaux in France. It was first described in 1806 based on samples found in the Hollertszug Mine in Herdorf, Germany. The mineral was named after the German polymath and poet Johann Wolfgang von Goethe (1749–1832). Composition Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle ironstone") but is more typically massive. Feroxyhyte and lepidocrocite are both polymorphs of ...

Crystal
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and " rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
