Semi-detailed Soil Survey of the LIuidas Vale Area, St. Catherine-St ...

THE SOILS
The second entry of the legend is Lithology (see Sub-chapter 2.4). A
differentiation is made between Parent rocks which denotes the nonconsolidated
bedrock underlying the soil profile, and Parent materials which
is an unconsolidated derivative of one or several types of parent rock. The
different parent rocks/materials as distinguished during the Lluidas Vale
Survey are listed in Table 10.
Within the miscellaneous land type, two subdivisions are recognized: ponds
(p) and rural residential areas (u).

F Fluvio-colluvial deposits
The third entry is for soil characteristics; a short description of the major
soil(s) within the mapping unit is given.
Each mapping unit description starts with a code (for correlation to the map),
and is followed by the name of the major Soil Series, a short description of
the characteristics of the major soil(s) and the USDA Soil Taxonomy
classification name.
The code is made up of three symbols referring to the legend entries, the
first for landform, the second for lithology and the third for soil
characteristics (arabic figure). In case the mapping unit includes only one
soil (whereby 25% of inclusions are allowed), the mapping unit is called
Consociation (see Glossary) and the code will look like (e.g.) B03. If two or
more major soils are distinguished within the map unit, x or y are placed in
between the second and third abbreviation, and the code will look like (e.g.)
PRxl or BOyl. The "x" indicates the mapping unit is a Complex; the "y"
indicates an Association. A complex has such an intricate soil pattern that
