The mining industry therefore stagnated and up to the early 1980s, as there were no significant new investments in Ghana‟s mining sector.
Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone. When there is a significant amount of clay or silt, geologists refer to the rock as argillaceous sandstone. The color of sandstone varies, depending on its composition.

Quartz and feldspar account for about 60 percent of slide area. Grains are mostly xenoblastic with curving boundaries and random orientation. Maximum grain size is 3.6 mm (feldspar phenocryst), modal size covers a significant range from about .15 to 1.4 mm. Many of the larger quartz grains present strain induced wave extinction.
The Precambrian Grenville rocks of the Appalachian/Piedmont region, located along the spine of the Appalachians, peek through the sedimentary rock cover such as in the Adirondacks of the Inland Basin region (Figure 6.10). Associated with the Grenville rocks in Pennsylvania and Maryland are significant deposits of zinc ore, in its most common form, sphalerite (ZnS).
