Rock Collection - Igneous

The rock collection in this science kit is the real deal! Igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. Over 700 types of igneous rocks have been described, most of them formed beneath the surface of the Earth's crust. So much for young geologists to learn with the 12 handpicked rock specimens, chosen for their color, texture and beauty. The identification chart and information guide will give kids a great introduction to identifying igneous rock specimens.

Rocks included: Ropy Lava, Tuff, Porphyry, Pumice, Obsidian, Diorite, Pegmatite, Scoria, Pearlite, Rhyolite, Basalt, and Granite. The handy storage tray helps keep your specimens organized. Start your own rock collection today!
