Prez Says...

by Dan Teich, MSDC President

The Earth’s crust is composed of mostly four elements: oxygen, silicon, aluminum, and iron. Another 90 elements account for the remaining 12%! If it's not a silicate or made of aluminum or iron, you can basically consider any other mineral or element rare. Keep in mind that all of the gold ever mined can fit in a cube under the Eiffel Tower. That’s it!

All of our technology, housing, and food is either mined, grown, or both. Sensitive electronics require an array of minerals and elements from all corners of the Earth, with many being exceedingly rare. Last month Leigh Broadhurst brought us to areas of ancient shield rocks which hold the bulk of rare minerals. While not the “pretty” rocks of the mim Museum, these minerals are essential for the operations of our modern world. Dr. Broadhurst's presentation built upon several recent talks to the MSDC concerning mineral use and rarity, including minerals in Greenland. 

On a personal note, we went up to Franklin, NJ, on Saturday, April 26, for the swap at Franklin Pond. Sadly the weather did not cooperate, but we did pick up a few great prehnites from a longtime friend. 

Keep collecting, learning, and having fun.
