This guide explores key metamorphic rocks, focusing on their foliated and non-foliated classifications. Foliated rocks include slate, phyllite, schist, and gneiss, each with distinct parent rocks. Non-foliated examples include marble, which originates from limestone and reacts with hydrochloric acid, and quartzite, derived from sandstone, with Baraboo quartzite containing significant hematite deposits. Additionally, anthracite coal, known for its shiny appearance, is formed from bituminous coal. Learn to identify and differentiate these rocks based on their characteristics and origins.
E N D
Slate -foliated -parent rock is slate
Phyllite -foliated -parent rock is slate
Schist -foliated -parent rock is phyllite
Gneiss -foliated -parent rock is schist
Marble -nonfoliated -parent rock is limestone (REACTS WITH HCl!!!)
Quartzite -nonfoliated -parent rock is sandstone
Baraboo Quartzite -nonfoliated -parent rock is sandstone and large deposits of hematite
Anthracite coal -nonfoliated -parent is bituminous coal -notice how shiny it is compared to it parent
