### sch.3-sec.7 Meaning of weathered rock
Weathered rock is loosely consolidated material—
in which there has been minimal biological activity; and
that is more like fresh, unweathered rock than the soil material above.
For subsection (1) , the material may be any of the following as defined under the field handbook—
partially weathered rock;
saprolite;
decomposed rock.
Features distinguishing weathered rock from soil are—
a markedly increased occurrence of rock fragments compared with soil layers above; or
a presence of a ‘ghost rock’ structure in which the material has the outline of rock layers or fragments but is as soft as the overlying soil layers; or
a predominance of ‘mealy’ material with a characteristic gritty appearance similar to fine ‘crusher dust’ or ‘deco’.
