azurite – mineral of the day

Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits. It is also known as Chessylite after the Chessy-les-Mines[1] near Lyon, France, where striking specimens have been found. The mineral has been known since ancient times, and was mentioned in Pliny the Elder’s Natural History under the Greek name kuanos (“deep blue,” root of English cyan) and the Latin name caeruleum The blue of azurite is exceptionally deep and clear, and for that reason the mineral has tended to be associated since antiquity with the deep blue color of low-humidity desert and winter skies. The modern English name of the mineral reflects this association, since both azurite and azure are derived via Arabic from the Persian lazhward, an area known for its deposits of another deep blue stone, lapis lazuli (“stone of lazhward”).

Mineralogy

Azurite crystals are monoclinic, and when large enough to be seen they appear as dark blue prismatic crystals. Azurite specimens are typically massive to nodular, and are often stalactitic in form. Specimens tend to lighten in color over time due to weathering of the specimen surface into malachite. Azurite is soft, with a Mohs hardness of only 3.5 to 4. The specific gravity of azurite is 3.77 to 3.89. Azurite is destroyed by heat, losing carbon dioxide and water to form black, powdery copper(II) oxide.

I just realized that I may not have sent you the sites for the albums my wife put together from our Tucson trip. We couldn’t get useful WIFI connections during our stay at the Beaudry RV park so we waited until we got home to sum it up pictorially.

new micromineral forum

Filed under: regular postings — Gary @ 10:22 pm

Phil stopped by and sent me an email about his new micromineral forum.  Its in french but he does have an english section to his forum- although the sign-up page is in french :)   Here is his loosely translated article on his forum.  If micro minerals is your hobby, check it out and knowing a bit of french would also help…
micromineral_forum

My name is Philippe Saget from Brittany (in France), 55 years old. I am applied geologist in oceanography at Ifremer (http://www.ifremer.fr). I am currently working on the polymetallic nodules – the ´†futur†eldorado†ª†!!!

After collecting macro-minerals, I was living in a flat on the third floor without elevator. I had the main mineral categories (fluorite, galena, pyrite…) but impossible to make evolve my collection. Moreover, the search for beautiful samples in Brittany and France in general being done very rare, I thus chose the micro-mineral collection.

Diamond star thrills astronomers- biggest diamond in universe

Twinkling in the sky is a diamond star of 10 billion trillion trillion carats, astronomers have discovered.

The cosmic diamond is a chunk of crystallised carbon, 4,000 km across, some 50 light-years from the Earth in the constellation Centaurus.

It’s the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk.

Astronomers have decided to call the star “Lucy” after the Beatles song, Lucy in the Sky with Diamonds.
