Abstract


In many fine-grained limestones, the differentiation of mechanical compaction and early cementation is difficult because of the frequent lack or ambiguity of compaction indicators. Here, a new, complementary criterion is proposed for the assessment of compaction in fine-grained carbonates: the deformation of thin-walled organic microfossils within the sediment. It is shown that they are reliable indicators of compaction. Two general styles of preservation can be distinguished: early cemented limestones contain spherical to slightly deformed microfossils whereas mechanically compacted carbonates always show flattened specimens.
