Bedrock is the rock, usually solid, that underlies soil or other unconsolidated, superficial material (regolithes). The most common bedrock in our country is what usually is called the crystalline basement.This was formed roughly one to two billion years ago, through igneous, sedimentary and metamorphic processes.he bedrock is characterised by its rock types. The rock types, igneous, sedimentary and metamorphic rocks are in turn built from combinations of rock-forming minerals. The rock may be dominated by a number of minerals or of one or two separate minerals, called major minerals.
