👉 Bedding fluid, also known as pore fluid, is a liquid or semi-fluid substance that fills the microscopic spaces between sedimentary grains in sedimentary rocks. This fluid, which can be water, gas, or a mixture of both, plays a crucial role in the diagenetic processes that transform loose sediment into solid rock. It facilitates chemical reactions by dissolving and redepositing minerals, aiding in cementation, dissolution, and the overall consolidation of sedimentary layers. Bedding fluid can also influence the physical properties of the rock, such as porosity and permeability, by altering grain-to-grain contact and creating pathways for fluid movement. These processes are essential in the formation of various sedimentary rock types, including sandstone and shale.
