March 26, 2017 Weekly Geology Guest, Treasures of the Earth

March 25, 2017
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
Wow!  Lots of great choices for my next geologic topic.
Voting was as follows:    1 for caves, 3 for geohazards, 1 for impact structures, 1 for mantle plumes, 1 for diamonds, 1 for Azores volcano collapse, 1 for global warming, and 3 for Geology the Good life from the Ground.
Me thinks that I will chose “Geology the Good Life from the Ground”.  We will incorporate this with the excellent NOVA documentary Treasures of the Earth.  They have kept it simple, as if this stuff can be called simple.  The first being gemstones (diamonds, sapphires, rubies, emeralds,opal), the second is metals (gold, copper, iron, steel), while the third is power (fossil fuels, solar, wind, nuclear).

Program Description

“Treasures of the Earth:  Gems, Metals, and Power” is a 3-part series that will take us on a journey deep inside Earth to uncover the mysteries of how these treasures were created, and to explore how they have allowed humankind to progress and build our great civilizations. But even as that quest continues, we are discovering that some of our treasures may soon run out or have unintended consequences that bring new perils. Can our ancient treasures reveal new secrets that will help us solve the problems we face today? “
With this program in mind we will touch multiple bases to include mantle plumes, “Global Warming”, Diamonds, and “The Good Life from the Ground”.

>    Let me know if all 3 of the programs will run, especially the HD.
>    I have included all 3 so the viewers can browse at their leisure for the next 3-weeks (maybe +).

1.    Gems:  Program Description

Their beauty has captivated us for millennia. Their cost can be extraordinary–some are even considered priceless. Precious gems like diamonds, rubies, emeralds, opal, and jade are the ultimate treasures of the earth, and each one is made from a specific–and often torturous–recipe of chemistry, pressure, and heat. The secrets to their sparkle, color, and even strength lie deep inside the gems themselves, but could they also hold clues to one of the most enduring mysteries in the field of geology? From Tiffany’s workshop in New York to the sapphire mines of Sri Lanka, from North Carolina’s emerald fields to the jade-laden Forbidden City of China, join NOVA in the first episode of a 3-part series, “Treasures of the Earth,” as we explore the fascinating science of gems.

I will not dive into gemstones until next week.  Way too much material to digest.
