WebIt depends on several factors: (1) chemical composition of the rock ( i.e., mineral content), (2) fluid content (type and degree of saturation of the pore space); the presence of water increases the thermal conductivity ( i.e., enhances the flow of heat), (3) pressure (a high pressure increases the thermal conductivity by closing cracks which ... WebMetamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure).
