Description
Introduce students to one of Earth’s most common volcanic rocks with this pack of 10 Basalt specimens. Each sample, averaging 3–4 cm, showcases the dense, fine-grained texture and distinctive grey to black coloration that makes basalt an essential study material in geology.
Formed from rapidly cooled lava, basalt contains less than 52% silica, giving it a low viscosity and allowing it to flow easily during volcanic eruptions. Its durability and abundance make it a key component of the oceanic crust and an excellent teaching tool for explaining igneous rock formation, volcanic activity, and plate tectonics.
Perfect for classrooms, labs, and educational collections, this set provides consistent, hands-on specimens for group study. Whether you’re demonstrating rock textures, discussing mineral composition, or exploring volcanic processes, basalt offers a clear and practical example.
