Peat

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.
