After peat comes coal on
Geofacts No. 11. It said, somewhere, that 10 feet of peat are compressed into 1 foot of coal. Apparently, that is not considered the process of metamorphosis. As I understand, metamorphosis transforms bituminous coal into anthracite coal, a harder, cleaner fuel. We have mostly bituminous coal in Ohio.
Geofacts No. 11 states that bituminous coal is a sedimentary rock.
Mansfield was a great user of coal in the past. I know this because I have crawled around in attics of older buildings in my younger years. There was much coal smoke dust. I would come out covered in it.
It took me a couple days to get this image. This is the only piece of coal in my collection of rocks and minerals. It came glued to card with other samples. I removed it to photograph it. I have tried to remove the glue but it is still visible when viewed closely.
