Anthracite is mostly found in east-central and northeast Pennsylvania in highly folded rocks. Most veins are difficult to mine as they are at high angles and not in flat deposits. This coal was formed during the carboniferous (Pennsylvainian) era ~ 300 MYA.
Small deposits are also found in Arkansas as well as China...but the vast majority is in Northumberland, Schuylkill, Carbon, Lackawanna and Luzerne Counties of Pennsylvania

What are the protoliths of Schist and Anthracite coal?
The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
How was Anthracite Coal discovered?
Anthracite coal was discovered through surface outcroppings and natural erosion exposing the coal seams. Native Americans used anthracite for fuel before European settlers arrived in North America. In the early 19th century, it became an important source of fuel for heating and industry.
