Size: 19.3 x 14.2 x 5.5 cm
Type: Igneous extrusive (volcanic) rock
Description: Volcanic rock (or lava) that characteristically is dark in color (gray to black), contains 45 to 53 percent silica, and is rich in iron and magnesium. Because of basalt’s low silica content, it has a low viscosity (resistance to flow). Therefore, basaltic lava can flow quickly and easily move >20 km from a vent.
Basalt is a fine-grained volcanic rock consisting predominantly of plagioclase (P), pyroxene, ± opaque minerals (magnetite, ilmenite). In terms of texture, basalts are usually hypocrystalline, aphanitic, and commonly porphyric.
Essential minerals: plagioclase, mafic minerals
Non-essential minerals: hornblende, biotite and/or pyroxenes
