20 igneous rocksSample pieces: 90x120 mmSorted into collection boxes and delivered in a wooden caseOur range of systematic rock collections includes many options,from small to large educational collections, covering the basics for bothbeginner and advanced petrography courses.This collection includes:igneous rocks (e.g., pegmatite, granite, granodiorite, syenite, plagioclase rocks,feldspar rocks, mafic rocks)volcanic rocks (e.g., rhyolites, trachytes, latites, basalts, porphyrites, selbergites,nephelinites, and pyroclastites)The specimens are provided with labels indicating their exact name, age, and location. A protective film covers each label to prevent scratching. The rocks are numbered so they can be easily re-identified in case one is misplaced.
