Granitic type soils
WebThe nature of the saprolite is influenced by the type of rock from which it develops, and it determines the chemical and physical properties of the associated soils. Saprolite covers are commonly thick on rocks such as granite, granitic gneiss, schists and sandstone, but they are thin over basaltic or mafic rocks. WebComments: Granitic Flatrocks are clearly closely related to glade and barren communities on other rock types, sharing features of ecology, vegetation struc ture, and species composition. Thus, this community type could as easily be termed “Granitic Glade.” The flatrock name has been retained because of its long and well-established usage.
