Peat |
I don't think that I would have thought of peat as a mineral. After all, it is plant remains. I guess that it falls into minerals and rocks because it is precursor to coal. I suppose that it is the process of metamorphosis that changes it into coal.
Geofacts No. 11 says that it takes 10 feet of peat to make 1 foot of coal. Would that make coal a metamorphic rock? Stay tuned, we will discuss that tomorrow. Peat is a wonderful addition to soil for added humus. I sometimes add it along with sand to lighten soil which is mostly clay. It really takes a lot! I don't suppose that it would be practical to apply it to farm fields.
