Actually there is a little bit courser layer of sandy quartz.
I can bring the experience I have had into the classroom and help the students
realize the relevance of what they are learning about.
Mud stone is really close.
Part of it is the mystery of the geologic processes that are going on around us.
And then you can get a nice view of the rock and what's in it. So give it a try.
I bring my enthusiasm into the classroom and into the lab, and students
sense that right away and it helps them get enthusiastic.
Every rock has a story to tell, you just have to know its language.
