Sedimentary Rock Set 15, 1 Each

The United Scientific® Sedimentary Rock Set 15 is a boxed collection of 15 sedimentary specimens, including breccia, sandstone, mudstone, shale, chert, flint, limestone, rock salt and bituminous coal. Specimens average 2 x 3 x 1.5 cm, and a specimen key inside the box identifies each one. Earth science teachers use the set to teach clastic, chemical and organic rock origins and the environments that deposit them.
