Allochem
text:
Allochem is a term introduced by Folk to describe the recognisable "grains" in carbonate rocks. Examples would include ooids, peloids, oncolites, pellets, fossil or pre-existing carbonate fragments. Fragments are still termed allochems if they have undergone chemical transformations – for example if an aragonite shell were to dissolve and be later replaced by calcite, the replacement would still be deemed an allochem. The allochems are typically embedded in a matrix of micrite or sparry calcite.
