Loveringite
Loveringite is a rare metallic oxide mineral of the crichtonite group with the chemical formula . It is a late-stage magmatic mineral, formed in the residual melt of mafic layered intrusions in either the olivine-chromite, pyroxene, or plagioclase-rich layers. Discovery and occurrence Loveringite was discovered in 1978 in the Jimberlana Intrusion, Dundas Shire, Western Australia, and was named for Australian geochemist and University of Melbourne professor John Francis Lovering, in recognition of his work on fission-track methods in geochemistry. Loveringite has also been generally found in areas of medium-grade metamorphism, reported from the Hoggar Mountains of Algeria; the Hohe Tauern Mountains, Salzburg, Austria; the Koitelainen intrusion of Lappland, Finland; Bourg d’Oisans, Isere, France; Bracco, Liguria, Italy; the Kerguelen Islands; the Khibiny Massif in the Kola Peninsula of Russia; and at Makwiro on the Great Dyke in Zimbabwe. Crystallography Loveringite is trigo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Oxide Minerals
The oxide mineral class includes those minerals in which the oxide anion (O2−) is bonded to one or more metal alloys. The hydroxide-bearing minerals are typically included in the oxide class.

Geochemistry
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. It is an integrated field of chemistry and geology. History The term ''geochemistry'' was first used by the Swiss-German chemist Christian Friedrich Schönbein in 1838: "a comparative geochemistry ought to be launched, before geognosy can become geology, and before the mystery of the genesis of our planets and their inorganic matter may be revealed." However, for the rest of the century the more common term was "chemical geology", and there was little contact between geologists and chemists. Geochemistry emerged as a separate discipline after ...

Khibiny Massif
The Khibiny Mountains (russian: Хиби́ны ; sjd, Umptek) is one of the two main mountain ranges of the Kola Peninsula, Russia, within the Arctic Circle, located between Imandra and Umbozero lakes. The range is also known as Khibiny Massif, Khibinsky Mountains, Khibinsky Tundras, Khibins or Khibiny. The Khibiny National Park was set up in 2018. Geography The Khibiny Massif are the highest mountains of the Kola Peninsula, a large peninsula extending from northern Russia into the Barents and White seas. The total land area of the peninsula is approximately . It is rich in minerals due to the removal of a layer of soil during the last ice age. The Khibiny Massif is of oval shape of about 1,300 km2. and occupies the central part of the peninsula at a relative elevation of 900–1000 m above the surrounding plain. The mountains are not particularly high; the two highest peaks are the Yudychvumchorr, which stands , and the Chasnachorr, which stands . The average elevati ...

Kerguelen Islands
The Kerguelen Islands ( or ; in French commonly ' but officially ', ), also known as the Desolation Islands (' in French), are a group of islands in the sub-Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged in the southern Indian Ocean. They are among the most isolated places on Earth, located more than from Madagascar. The islands, along with Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and France's Scattered Islands in the Indian Ocean, are part of the French Southern and Antarctic Lands and are administered as a separate district. The main island, Grande Terre, is in area, about three quarters of the size of Corsica, and is surrounded by a further 300 smaller islands and islets, forming an archipelago of . The climate is harsh and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round. There are no indig ...

Lapland (Finland)
Lapland ( fi, Lappi ; se, Lappi; smn, Laapi; sv, Lappland; la, Lapponia, links=no) is the largest and northernmost region of Finland. The 21 municipalities in the region cooperate in a Regional Council. Lapland borders the region of North Ostrobothnia in the south. It also borders the Gulf of Bothnia, Norrbotten County in Sweden, Troms and Finnmark County in Norway, and Murmansk Oblast and the Republic of Karelia in Russia. Topography varies from vast mires and forests of the South to fells in the North. The Arctic Circle crosses Lapland, so polar phenomena such as the midnight sun and polar night can be viewed in Lapland. Lapland's cold and wintry climate, coupled with its relative abundance of conifer trees such as pines and spruces, means that it has become associated with Christmas in some countries, most notably the United Kingdom, and holidays to Lapland are common towards the end of the year. However, the Lapland region has developed its infrastructure for year-round ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...
