  • Felsic Igneous Rocks: Types, Characteristics & Examples
    Here are four common felsic igneous rocks:

    1. Granite: This is the classic example of a felsic rock. It's coarse-grained and often has a light color, with visible crystals of quartz, feldspar, and mica.

    2. Rhyolite: Rhyolite is the extrusive (volcanic) equivalent of granite. It has a similar composition, but due to its rapid cooling, it has a finer-grained texture, sometimes appearing glassy.

    3. Obsidian: This volcanic glass forms when lava cools very quickly, resulting in a smooth, black, and often shiny surface. While it's technically a volcanic rock, its composition aligns with felsic rocks.

    4. Pumice: Another volcanic rock, pumice is full of air bubbles (vesicles) that formed as gases escaped from the lava. It's light and porous, often used as an abrasive. Pumice also falls into the felsic category.
