Typic Aquisalid:

	This soil is typical of those found in the Basin and Range Province of the US. White crust at the soil surface is a mixture of various soluble salts. High salt content in the upper profile inhibits the growth of most plant species.

Fine, kaolinitic, thermic Typic Kanhapludult:

Piedmont region of the southeastern USA.
-Virginia to Alabama.

Parent Material
- felsic, igneous, and metamorphic rocks

The Bt horizons typically have clay textures ~70% clay.
- kaolinite and hydroxy-interlayered vermiculite.
