Study Notes
Non-Foliated Metamorphic Rocks
- Non-foliated metamorphic rocks are characterized by the absence of layering.
- These rocks typically consist of a single type of mineral.
Quartzite
- Composed primarily of silica (quartz).
- Derived from felsic parent rocks, which are rich in silica.
- Available in a variety of colors and is harder than glass.
- Does not react with acid (won't fizz).
Marble
- Formed from calcite or dolomite.
- Originates from carbonate parent rocks.
- Can exhibit various colors and is softer than glass.
Dolomite Marble
- Exhibits slight or negligible fizzing when exposed to acid.
Calcite Marble
- Reacts positively with acid, producing fizz.
Amphibolite
- Comprised mainly of amphiboles, with possible inclusion of feldspars.
- Developed from intermediate or mafic parent rocks, which contain higher levels of iron and magnesium.
Serpentinite
- Made predominantly of the mineral serpentine.
- Results from the alteration of ultramafic rocks in the presence of water.
- Recognized as California's state rock and has a texture reminiscent of snake skin.
- Does not react with acid (no fizz).
Hornfels
- A dark, fine-grained rock formed through contact metamorphism, typically due to nearby intrusions of molten rock.
- Composed mainly of hornblende (an amphibole) and feldspar.
- Almost any type of parent rock can be transformed into hornfels through intense heat.
Summary of Non-Foliated Metamorphic Rocks
- Key examples include quartzite, marble, serpentinite, amphibolite, and hornfels.
