Introduction. Descriptions of cone-in-cone and arguments over its genesis date back to the eighteenth century. The common characteristic that defines the structure is that it is an accumulation of a mineral (usually calcite) comprising fibrous or bladed crystals which form conical aggregates within a rock. These nodules show the close association of a classical micritic/microsparitic internal sediment with areas where cone in cone structures prevail.
