SOIL HORIZON DESCRIPTION:
Fines seem to be washed out of
the upper part of the A-C horizons.
Ah1: 0-7 cm; Brown (10YR 4/3)
sandy loam, very weak coarse granular structure, very friable, many fine and
very fine roots, slightly calcareous, 15% 0.2-2 cm gravel, made of basalt
(70%) and pumice (30%), no rock fragment weathering, clear smooth boundary.
Ah2: 7-40 cm; Dark greyish
brown (10YR 4/2) loamy sand, structureless, many fine and very fine roots,
slightly calcareous, 30% 0.2-2 cm gravel, made of basalt (70%) and pumice
(30%), no rock fragment weathering, clear smooth boundary.
40-68 cm; Yellowish brown (10YR 5/4) sandy loam, structureless, few very fine
roots, slightly calcareous, 10% 0.2-2 cm gravel, made of basalt (70%) and
pumice (30%), no rock fragment weathering, abrupt wavy boundary.
C2: 68-100 +cm; Brown (10YR
5/3) sandy loam, weak fine and medium subangular blocky structure, very
friable, no roots, slightly calcareous, 30% 0.2-2 cm gravel, made of basalt
(70%) and pumice (30%), no rock fragment weathering, original Minoan IV
ochric horizon (0-40 cm); calcaric soil material (40->100 cm); no Arenosol
because of >35% coarse fragments between 0 and 40 cm:
(1999): ochric epipedon (0-40 cm); Psamment
because texture is assumed to be loamy fine sand or coarser in the
particle-size control section (very fine sand fraction not determined, but it
is unlikely that there is 50% or more very fine sand):
