Eisco - Raw Basalt Specimen, 3" Hand Sample - Aphanitic Igneous Rock - Ideal for Geology Classrooms, Igneous Rock Identification & Earth Science Lessons

This raw basalt hand sample from Eisco provides a tangible representation of a common aphanitic igneous rock found predominantly in Earth's oceanic crust. Basalt forms rapidly from iron-rich magma, resulting in its distinctive dark color and fine-grained texture. Measuring approximately 3 inches, this large hand-sized specimen offers students an excellent opportunity for detailed observation and easy handling.Ideal for geology classrooms, the basalt sample is useful in teaching igneous rock classification, volcanic processes, mineral composition, and Earth’s tectonic activities. It serves as a versatile teaching tool that helps illustrate geological concepts aligned with Next Generation Science Standards (NGSS).
