Rocks and Minerals of the U.S. Basic Collection (35 pcs.)
Much like the above collection, only with fewer specimens. The 35 or 24 rocks and minerals form a more abbreviated, but still adequate, range of materials for your study of geology or for identification/reference. Instead of buying one of those overpriced "book and skimpy rock collection" combo sets that pervade the market, settle on a good, basic book about rocks and rock-collecting, and use one of these sets as your samples. Unmount the specimens if you prefer - either way, you'll have a much larger and more complete collection for about the same price. Rocks in Basic set measure ½"-¾" while those in the Reference collection are slightly larger at ¾"-1". Study Guide included.
Enhance your geology study with these beautiful rock collections! Each kit contains 15 number-coded rock specimens, an information chart, and a key sheet for identification. Rocks are displayed in a sturdy, compartmentalized plastic tray. Some of the rocks include schist, quartzite, marble (metamorphic), shale, sandstone, limestone (sedimentary), and granite, porphyry, and scoria (igneous). Each rock is approximately 1 ½ x 1 ½ inches.
