Pentti Eskola (geologist)
Pentti Elias Eskola (8 January 1883 – 6 December 1964) was a Finnish geologist who specialised in the petrology of granites and developed the concept of metamorphic facies. He won the Wollaston Medal in 1958, the Vetlesen Prize in 1964, and was given a state funeral upon his death. The mineral eskolaite is named in his honor. Eskola was born in Lellainen, the son of a farmer. He graduated from the University of Helsinki in 1906 and received a doctorate in 1914 with a dissertation on the petrology of the Orijärvi Region. Eskola was a student of Wilhelm Ramsay Wilhelm Ramsay (20 January 1865 – 6 January 1928) was a Finland Swede geologist.

Honkilahti
Honkilahti ( sv, Honkilahti, also ) is a village and a former municipality in Finland, part of Eura since 1970. History The commune of Honkilahti was founded in 1904 when it was separated from Eura. Honkilaht was merged back with Eura in 1970. Honkilahti has a wooden church which "Tuomas Samuelinpoika Rahvenius" designed in 1759. It lies on the northern side of Koskeljärvi. Before Honkilahti were discontinued, it had many kilometers the coastline from Pyhäjärvi. The population of Honkilahti was at its peak in 1957 when there were 1887 inhabitants. The neighbouring municipalities of Honkilahti were Eura, Hinnerjoki, Laitila, Karjala, Mynämäki, Yläne and Säkylä. The arms of Honkilahti were designed by Gustaf von Numers and it was registered in 1951.

Eskolaite
Eskolaite is a rare chromium oxide mineral (chromium(III) oxide Cr2O3). Discovery and occurrence It was first described in 1958 for an occurrence in the Outokumpu ore deposit of eastern Finland. It occurs in chromium bearing tremolite skarns, metamorphosed quartzites and chlorite bearing veins in Finland; in glacial boulder clays in Ireland and in stream pebbles in the Merume River of Guyana. It has also been recognized as a rare component in chondrite meteorites. The mineral is named after the Finnish geologist Pentti Eskola (1883–1964). Structure and physical properties Eskolaite crystallizes with trigonal symmetry in the space group ''R'c'' and has the lattice parameters a = 4.95 Å and c = 13.58 Å at standard conditions. The unit cell contains six formula units. The lattice is analogous to that of corundum, with Cr3+ replacing Al3+.

Academic Personnel Of The University Of Helsinki
An academy ( Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jakob Sederholm
Jakob Johannes Sederholm (20 July 1863 – 26 June 1934) was a Finnish petrologist most associated with his studies of migmatites. Troubled by illness throughout his life, Sederholm originally chose to study geology to allow him to work outdoors. After studying first in Helsinki (where he was a student of Fredrik Johan Wiik), then in Stockholm and Heidelberg, Sederholm returned to Finland to work for the Geological Survey of Finland. In 1893 he assumed the role of director of this institution, a post he occupied until his death forty years later. Working on local Precambrian basement rocks, Sederholm instigated a map-making programme that, between 1899 and 1925, published many maps and descriptions of their geological history. Gneisses in the areas he studied (the so-called Baltic Shield) were often of mixed composition, with layers of granitic rock being interleaved with metamorphic rock. Sederholm termed these as migmatites, and viewed them as the product of the intrusio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eclogite
Eclogite () is a metamorphic rock containing garnet (almandine-pyrope) hosted in a matrix of sodium-rich pyroxene (omphacite). Accessory minerals include kyanite, rutile, quartz, lawsonite, coesite, amphibole, phengite, paragonite, zoisite, dolomite, corundum and, rarely, diamond. The chemistry of primary and accessory minerals is used to classify three types of eclogite (A, B, and C). The broad range of eclogitic compositions has led a longstanding debate on the origin of eclogite xenoliths as subducted, altered oceanic crust. Origins Eclogites typically result from high to ultrahigh pressure metamorphism of mafic rock at low thermal gradients of < as it is subducted to the lower crust to depths in a subduction zone.
