June 18, 2017 Weekly Geology Guest

June 17, 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.

This week we will take a peek at the minerals associated with iron.

IRON
Iron is the cheapest and fourth most abundant metal on Earth.
Iron is a common element in many minerals. The minerals goethite, hematite (ferric oxide), lepidocrocite, magnetite (iron oxide) and siderite (iron carbonate) are all mined for iron. The largest concentrations are in iron-rich sedimentary rocks, and such deposits are mined in Russia, Brazil, China, Australia, India and the USA.

The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World (Afro-Eurasia) when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia and the Stone Age in Africa, with exceptions. Meteoric iron has been used by humans since at least 3200 BC. Ancient iron production did not become widespread until the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy were developed. The start of the Iron Age proper is considered by many to fall between around 1200 BC and 600 BC, depending on the region.

Next week I will venture into Fossil Fuels.
We will ignore steel, since it is based on Iron.

 
Enjoy the adventure!
 
Thanks,
