Intraclasts Wikipedia

Intraclasts are irregularly shaped grains that form by syndepositional erosion of partially lithified sediment. Gravel grade material is generally composed of whole disarticulated or broken skeletal fragments together with sand grade material of whole, disaggregated

limestone Characteristics, Uses, & Facts Britannica

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil

Micropaleontological study of the limestone olistoliths

Three main groups of calcareous olistoliths were separated, related to limestone age: Tithonian, Berriassian and Barremian-Aptian. Each group is characterized by its micropaleontological content. Tithonian limestones are rare among the limestone olistoliths.
