Significant uranium potential in Botswana
Creamer Media's Mining Weekly    Share    Share on FacebookTwitterShare on LinkedinE-mail article
ASX-listed uranium, nickel and gold explorer Impact Minerals asserts that Botswana is fast growing its reputation as one of the best modern-era uranium mining provinces on the African continent, owing to the company's discovery of three deposits and a new emerging discovery at its Red Hills prospect. The discovery of the Lekabolo deposit, in 2010, led to the discovery of further deposits, namely Mosolotsane and Morolane, and has delivered substantial exploration opportunities in eastern Botswana.

Share   Share on FacebookTwitterShare on LinkedinE-mail article
The Geochemical Society and Meteoritical Society are pleased to announce that Dr. Marc Norman of the Australian National University, Research School of Earth Sciences, has been appointed as the new Executive Editor of Geochimica et Cosmochimica Acta. Norman will assume the position starting April 17, to become just the ninth Executive Editor in the 62-year history of the journal. Norman will be working with the Publisher, Elsevier, and the dedicated board of Associate Editors to ensure that GCA maintains the standard of excellence in geo/cosmochemistry publication for which it has been known since Volume 1 in 1950.

Isotopomer 2012
GS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The 6th International Symposium on Isotopomers (ISI-2012). June 18-22, 2012, at Carnegie Institution of Washington, Washington DC.

The ISI symposium has traditionally made strong contributions towards understanding mass independent isotope fractionation and site-specific isotope systematics in a range of disciplines. Contributions are especially invited on theory, experiments and applications of clumped isotope research. Registration and abstract deadline is May 1.

Acidity in ocean killed Northwest oysters, new study says
The Seattle Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It's been eight years since baby oysters started dying by the billions at an Oregon hatchery and in Washington's Willapa Bay. In 2009, top scientists drew global attention when they said evidence suggested the culprit might be changing ocean chemistry from the same greenhouse gases that contribute to global warming. They just couldn't prove it — until now. More

University and industry explore geothermal energy in Nevada
Reno Gazette-Journal    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Nevada has produced electrical power from geothermal energy for nearly 30 years. It now has 22 plants operating at a dozen sites capable of producing 469 megawatts. Estimated resource potential in the state is more than 2,000 megawatts, or twice the production of the hydroelectric plant at the Hoover Dam. More

Rising Pacific linked to climate change
IOL SciTech    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Sea levels in the southwest Pacific started rising drastically in the 1880s, with a notable peak in the 1990s thought to be linked to human-induced climate change, according to a new study. The research, which examined sediment core samples taken from salt marshes in southern Australia's Tasmania island, used geochemistry to establish a chronology of sea level changes over the past 200 years.
