If the chips in your driveway formed over time, skim coating and sealing the surface is a simple cosmetic solution. For a new driveway, excessive chipping can indicate that the slab itself is weak. Causes for weak concrete include drying out the surface too quickly or low quality concrete.
Igneous rocks are rocks that have formed out of magma (molten rock). The two types of igneous rocks most common on Earth are called granite and basalt. Granite is a rock that typically looks pink and white with black specks.Basalt generally just looks black.o summarize, the two types of igneous rocks by chemical composition are felsic and mafic. Granite-typically composed of orthoclase, hornblende, biotite, and quartz-is a felsic rock type. Basalt is mostly olivine, augite, and calcium-rich plagioclase, therefore mafic. slide 3 of 6.
Basalt is one of the most common rock types in the world. Basalt is the rock most typical of large igneous provinces. The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt.asalt which erupts under open air (that is, subaerially) forms three distinct types of lava or volcanic deposits: scoria; ash or cinder (breccia); and lava flows. Basalt in the tops of subaerial lava flows and cinder cones will often be highly vesiculated, imparting a lightweight frothy texture to the rock.
