Wackestone
Encyclopedia
Wackestone is a matrix-supported carbonate rock that contains over 10% allochems
in a carbonate mud matrix. This is part of the Dunham classification
of carbonate rocks. In the other widely used classification due to Folk
, an equivalent description would be, for example, an oopelmicrite, where the allochems
in question are ooids and peloids.
Allochems
Allochem is a term introduced by Folk to describe the recognisable 'grains' in carbonate rocks. Any fragment from around ½mm upwards in size may be considered an allochem. Examples would include ooids, peloids, oncolites, pellets, fossil or pre-existing carbonate fragments...
