The ratio of clay to other minerals is variable. Shale is characterized by breaks along thin laminae or parallel layering...

 34 feet (10.4 m) above the bottom. Above this shaly part lies the Irondale ore bed, which is separated from the Big Seam of iron ore by a few feet of shale and of sandstone layers that carry large and small waterworn pebbles. Next above lies the Big seam, approximately 17 feet (5.2 m) thick, above which these is about 38 feet (11.6 m) of red sandstone that carries small quartz
Quartz
Quartz is the second-most-abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz,...

Red Mountain Expressway Cut

In 1970, the "Red Mountain Expressway" was completed after many years of work cutting through Red Mountain.
