Mountains
| These are soils developed on hornblende pyroxene granulites with some banded pyroxene granulites | Strongly dissected ridges | 50-more than 80 | Rockland and shallow to moderately deep, excessively drained dark yellowish-brown gravelly clay loams and sandy clays on saprolite occurring at variable depths |
Moderately to strongly dissected ridge crests and slopes | 30 - 80 | Shallow/deep to very deep, well to somewhat excessively drained, yellowish-brown to yellowish-red gravelly sandy clay loams to clays and moderately deep to deep well to somewhat excessively drained, brown to dark yellowish-brown, gravelly sandy clay loams. Topsoils are relatively thick and deep to very deep, moderately well to well-drained, dark brown to brown gravelly sandy clay loams to sandy (clays) with thick black sandy clay loam to clay loam topsoils. Surface stoniness and rock outcrops are common. | ||
Talus Slopes | 10 - 25 | Scattered rock outcrops and cliffs of rockfall and deep to very deep well-drained dark grayish brown to yellowish-brown, sandy clay loams to sandy clays. Topsoils are thick, sandy clay loams. Surface stones are common. | ||
Developed on muscovite biotitemigmatites | Strongly dissected hills | 45-80 | Rockland and shallow, excessively, drained, very dark gray, extremely gravelly sandy clay loams | |
Piedmonts | Developed on colluvium derived from hornblende pyroxene granulites and micaceous gneiss | Foothills | 15 - 45 | Deep to Very deep, well-drained, red to dark reddish-brown, clays with dark brown topsoil. Stone lines comprised mainly of fresh angular quartz gravel and stones are common. |
Glacis | 2 - 15 | Deep to very deep. Well-drained, reddish-brown to dark red, clays with weak to moderate structure | ||
Developed on colluvial/alluvial deposits derived from pyroxene granulites and micaceous gneiss | Alluvial fan | 0 - 2 | Very deep, well-drained, highly weathered, red, sandy clays to clays with humiferoustopsoils | |
Developed on colluvial/alluvial derived from biotite muscovite migmatites. | Alluvial fan | 2 - 10 | Very deep, well-drained, dark reddish-brown, sandy clay loams to sandy clays, with very thick loamy sand topsoils and very deep, excessively drained, very pale, sands and sandy clay loams with weak structure and profile development. | |
Peneplains | Developed on muscovite biotitemigmatites | Isolated hills | 10 - 30 | Rock outcrops and shallow excessively drained, gravelly sandy clay loams and sandy clays. |
Developed on colluvium with variable mineralogical composition | Ridge crests | 0 - 2 | Deep to very deep, well-drained, dark reddish-brown (reddish-brown) to red clays with moderate structure and profile development. The topsoils are brownish loams. Thick, ferruginous, gravelly subsoil layers are common | |
Ridge slopes | 5 - 8 | Deep to very deep, well-drained, brownish sandy clay loams to clays with moderate structure and profile development | ||
Developed on muscovite biotitemigmatites | Ridge crests and slopes | 2 - 5 | Moderately deep to deep, well to excessively drained, brownish and very pale sands on mixed bouldery and rocky subsoil and Deep to very deep, well-drained, brownish. Sandy clay loams to sand clays with poor to moderate structure and profile development. | |
Valleys | Developed on alluvial-colluvium with variable mineralogical composition | Ridge terrace | 0 - 1 | Very deep moderately well to imperfectly drained, very dark brown to brown, sandy clays to sandy clay loams with variable salinity and levels and very deep, moderately well to imperfectly drained, dark brown heavy cracking clays with thick, very dark grayish brown, clay topsoils |
Flood plain | 0 - 1 | Very deep, moderately well to imperfectly drained, dark brown heavy cracking clays with thick, very dark grayish brown clay topsoils and very deep, moderately well to imperfectly drained, very dark brown to brown, sandy cays to sandy clay loams with variable salinity and sodicity levels and very deep, poorly drained, dark brown to very dark brown. stratified and mottled sands and sandy clays |
