Finely Crystalline
Describes a texture of rocks or minerals with very small crystals that are often too small to be seen unaided, indicating rapid cooling or chemical precipitation.
Glassy Texture
A description of igneous rocks that cooled quickly from molten material, resulting in a non-crystalline or vitreous appearance.
- Learn about the influences and conditions that shape the textures of igneous rocks.
- Elucidate the sequence of events that lead to the cooling and solidification of magma or lava, and how these events influence the texture of the rock formed.
