- 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)
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!
