Members of the family Geodermatophilaceae, order Actinomycetales, contain bacteria isolated mainly from soils, seawater, and stone surfaces that have been grouped into the three genera Geodermatophilus, Blastococcus, and Modestobacter. Members of Geodermatophilus have been found mainly in soils, Blastococcus spp. have been found in a marine sediment and in stone interiors and Modestobacter spp. have been found on stone surfaces and in polar regolith. Members of the genera Geodermatophilus and Modestobacter have been found to be unusually resistant to oxidative stresses while those of Blastococcus were found resistant to some heavy metals and metalloids. This family is close to the genera Acidothermus, Cryptosporangium, Frankia, Nakamurella, Sporichthya, and Fodinicola and was grouped with them into suborder Frankineae. A recent rearrangement has resulted in the elevation of suborder Frankineae to order Frankiales (Normand and Benson, Order VI. Frankiales ord. nov. In: Bergey's Manual of Systematic Bacteriology, vol 5. The Actinobacteria. Bergey's Manual Trust, Athens, pp 509-511, 2012) containing families Acidothermaceae, Cryptosporangiaceae, Frankiaceae, Geodermatophilaceae, Nakamurellaceae, Sporichthyaceae, and Fodinicola.
