New Egyptian Tomb Find

... Archeologists have unearthed 57 ancient Egyptian tombs, most of which hold an ornately painted wooden sarcophagus with a mummy inside, Egypt's Supreme Council of Antiquities said Sunday.

The oldest tombs date back to around 2750 B.C. during the period of Egypt's first and second dynasties, the council said in a statement. Twelve of the tombs belong the 18th dynasty which ruled Egypt during the second millennium B.C..... more...

Greenland Rising 1 Inch Per Year

Via Geology.com

The ice that covers Greenland is melting reducing the weight of the landmass. As that happens the crust rises in response to the reduced weight. In some areas the rate of rise is an inch per year. It is amazing that climate change can result in the uplift of a landmass....

Grants for Deep Geology in Ohio

Via Farm and Dairy:

With likely federal regulation of carbon dioxide emissions on the horizon, the Ohio Air Quality Development Authority took action at its May meeting to advance the state’s understanding of the suitability of its deep geology for the sequestration of CO2....

OAQDA approved a grant from its Ohio Coal Development Office program for Battelle of up to $2,209,409 and a separate OCDO grant to the Ohio Department of Natural Resources of up to $790,591.

The funds are to be used for the 18-month project Conducting Research to Better Define the Sequestration Options in Eastern Ohio and the Appalachian Basin.

Animals Living Without Oxygen

Via Science:

Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin, which contains salt brine so dense that it doesn't mix with the oxygen-containing waters above.

Mineral of the Month

GAUDEFROYITE

Ca₄Mn³⁺_3-x(BO₃)₃(CO₃)(O,OH)₃

 

  Gaudefroyite (black), barite, andradite from KMF.

specimen and photo – J de Jongh

 

 

Crystal system: Hexagonal      Hardness:  6     Density:  3.35 – 3.50      Cleavage:  None, brittle.

Streak:  Brown                Colour:     Black, charcoal, bronze

Occurrence:                  An uncommon hydrothermal mineral in manganese deposits.

Habitat:                         Needle-like to stubby hexagonal crystals up to 5 cm long, with pyramidal terminations.

Composition:                Borate comprising of calcium, manganese, boron, hydrogen, carbon and oxygen.

 

The Tsumeb mine in Namibia is famous for its variety of green minerals that are difficult to distinguish from one another.  Likewise, the Kalahari Manganese Field near Kuruman, is well known for its various black minerals that can also be very tricky to identify accurately.  One such mineral is gaudefroyite.  Unfortunately, fairly limited information is available on this rare mineral.  In the early 1960s Pascal Gallo, chief miner at the manganese mine at Tachgagalt 17 km (some sources indicate 17 miles) south-southwest of Quarzazate, Morocco, noticed an association of unusual minerals in Vein No. 2 of the mine.  He presented a specimen of the material to Georges Jouravsky, chief geologist, “Division de la Geologie du Maroc”, who in turn passed it along to Abbe Christophe Gaudefroy (1888-1971), a French mineralogist who worked in Morocco.  Marokite was the first new mineral to be described from this mine.  Soon thereafter gaudefroyite, named after the abovementioned French mineralogist, was identified in 1964 from a sample apparently found on the dumps of the same mine.

 

The Kalahari Manganese Field is only the second reported occurrence in the world of this rare mineral.  It was discovered in the early 1990s at N’Chwaning II and Wessels mines.  Not only was it found as the best crystals, but also as the biggest crystals of the species in the world. 

 

Underground, the black crystals of gaudefroyite are difficult to distinguish from the manganese ore.  It is also often mistaken for vesuvianite from the Wessels mine.  Of interest to mineral collectors are those crystals up to 5 cm long and 1,5 cm in diameter, pitch black and in many cases doubly terminated, with well developed pyramidal faces which came from the N’Chwaning II mine in 1995.  The majority of these crystals were floaters or embedded in gypsum or calcite. 

 Associated minerals are sturmanite, calcite, hematite, andradite, todorokite, bixbyite, chlorite and barite.  Fine needle-like gaudefroyite from N’Chwaning II have been reported, occurring as cavity fillings in hausmannite.  These needles, only a few mm long, are bronze in colour.

Anthropocene - The New Epoch?

Via The Telegraph:

I Million Feet Drill Core Analyzed

Via Duluth News:

... On March 11, Mark Severson completed the visual analysis of 1 million feet of drill core with copper-nickel-platinum group element mineralization. Severson is a geologist at the Natural Resources Research Institute, at the University of Minnesota Duluth, and he began this task in 1987...

... Severson’s documentation helps mineral exploration companies understand the geology of this area of Minnesota, as well as the copper, nickel, platinum group element mineralization and other mineral deposits. This information is the backbone of the state’s evolving non-ferrous mining industry.
