Description
Discover the dynamic geology of volcanic terrain with this pack of 10 Andesite Rock specimens. Each sample showcases the classic gray to black appearance of andesite, a fine-grained volcanic rock enriched with distinctive mineral textures. Students will easily identify visible plagioclase feldspar crystals—often white—and hornblende crystals—typically black—embedded within the groundmass. Many specimens may also contain pyroxene, biotite, iron staining, or other natural inclusions, offering an authentic look at real geological variation.
These samples are an excellent teaching tool for lessons on igneous rock classification, mineral composition, porphyritic textures, and volcanic processes. The presence of larger phenocrysts makes each piece an ideal example of porphyry, enabling hands-on learning and visual comparison. Perfect for Earth Science, Geography, and classroom lab activities, this set provides reliable, high-quality specimens that support both group and individual study.
Durable, varied, and classroom-ready, these andesite specimens help students connect textbook concepts to real-world geology—making every lesson more engaging and interactive.
