Data for the horizon
Horizon sampled: C1
Depth sampled: 132-178 cm
Physical and chemical data available: See reference
Macromorphological description of horizon: 2.5 Y 5/6 moist sand; massive structure; 2.5 YR 4/6 lenses
Micromorphological description of horizon: Enaulic related distribution pattern (Bullock et al., 1985). The skeleton grains for the most part touch and therefore support each other.
Aggregates of finer material occur in a small part of the total space between skeleton grains. The finer material in the aggregates is isotropic. The pattern is weakly developed and approaches a manic related distribution pattern.
