... flows. The system is sealed internally by massive hemipelagites. When in channel axis, the net is almost 100% with an effective porosity around 22-25 pu and a slight clay content never exceeding 5%. Calcite cementation may occur locally and reduces porosity to almost zero in meter-thick beds. Levees...
