June 5. 2017 Weekly Geology Guest, Copper

June 3, 2017
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

For the next several weeks, roughly 5 weeks we will discuss the critical metals mentioned in Nova’s Treasures of the Earth.  These include gold, copper, bronze, iron, and steel.
Copper was one of the first metals to be worked into implements and the first metal to be smelted from ores. Its excellent ductility and high conductivity assure its use in modern society.

Azurite (Carbonate Mineral, Cu3(CO3)2(OH)2

is a soft, deep blue copper mineral produced by weathering of copper ore deposits. It is also known as Chessylite. 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.

COPPER
Copper was one of the first metals ever extracted and usedby humans, and it has made vital contributions to sustaining
and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C.,
and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. The discovery that copper alloyed with tin
produces bronze marked the beginning of the Bronze Age atabout 3000 B.C.
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a
result, copper was important to early humans and continues tobe a material of choice for a variety of domestic, industrial, and
high-technology applications today.

Next week I will venture into metals > Copper + Tin for the Bronze Age.

 
Enjoy the adventure!
 
Thanks,
