Michael Lesher
Carl Michael Lesher (born 1951) is an American geologist. He is an authority on the geology and origin of nickel-copper-platinum group element deposits, especially those associated with komatiites, their physical volcanology and localization, the geochemistry and petrology of associated rocks, and controls on their composition. Life, education, and career Lesher was born in Indianapolis, Indiana, United States, but has been living and working in Canada beginning in 1975 and continuously since 1997. He holds BSc and MA degrees in geology from Indiana University Bloomington, and a PhD degree in geology from the University of Western Australia. Between 1975 and 1979, he worked as an Exploration Geologist and Mineralogist for the Iron Ore Company of Canada; between 1982 and 1984, he was a Postdoctoral Research Fellow at the J. Tuzo Wilson Research Laboratories of the University of Toronto; and between 1984 and 1997, he was Professor of Economic Geology at the University of Alabama in ...

Komatiites
Komatiite () is a type of ultramafic mantle-derived volcanic rock defined as having crystallised from a lava of at least 18 wt% MgO. Komatiites have low silicon, potassium and aluminium, and high to extremely high magnesium content. Komatiite was named for its type locality along the Komati River in South Africa, and frequently displays spinifex texture composed of large dendritic plates of olivine and pyroxene. Komatiites are rare rocks; almost all komatiites were formed during the Archaean Eon (4.0–2.5 billion years ago), with few younger (Proterozoic or Phanerozoic) examples known. This restriction in age is thought to be due to cooling of the mantle, which may have been hotter during the Archaean. The early Earth had much higher heat production, due to the residual heat from planetary accretion, as well as the greater abundance of radioactive isotopes, particularly shorter lived ones like uranium 235 which produce more decay heat. Lower temperature mantle melts such as b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNESCO
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations (UN) aimed at promoting world peace and security through international cooperation in education, arts, sciences and culture.

Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Earth ...

Canadian Institute Of Mining And Metallurgy
The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) is a not-for-profit technical society of professionals in the Canadian minerals, metals, materials and energy industries. CIM's members are convened from industry, academia and government. History In March 1898, the Canadian Mining Institute was founded in Montreal at the second annual meeting of the Federated Canadian Mining Institute, which was dissolved. The Institute was incorporated by an Act of Parliament to include all former provincial groups except The Mining Society of Nova Scotia, which remained a separate body. In 1902, The Institute formed its first Branches in Sherbrooke, Quebec, Kingston, Ontario, and Nelson, British Columbia. In 1918, the Mining Society of Nova Scotia formally became affiliated with the Canadian Mining Institute In 1920, Metallurgy Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-met ...
