January 7 – Old Rock Day

Luckily, I am now related to a rock expert! My brother-in-law, Luke, is a graduate from University of Michigan with a degree in Geology. Jared called him today to ask him some questions about rocks…here is what we discovered:

•  The oldest rocks are Igneous and Metamorphic
• The oldest rocks can be found in Australia and date back 2.5-3.8 billion years
• “Rocks are cool” (that is a direct quote)
• Luke’s favorite rock: Gneiss (pictured above)
• Diamonds are NOT rocks…they are minerals, but diamonds are found in Kimberlights (which is a rock)

 I hope I have expanded your rock knowledge.

Jared and I got to thinking, in the rock world an OLD rock has to be pretty old. So treat them with respect…they may look tough, but they are eroding away everyday!
