sch.3-sec.7Meaning of weathered rock

### 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’.
