A first-order model for temperature rise for uniform and differential compression of sediments in basins
We deduce algebraic expressions for temperature rise for ideal cases of uniform and spatially varying compression of sediments of single mineralogy. According to the results of the present work, the temperature rise is related to the coefficient of volume expansion, isothermal compressibility, dimension, bulk density, and specific heat of the sediment columns. Rise of temperature due to compression of sediment is effectively inversely proportional to the volume coefficient of expansion (or contraction) of sediments. Compression-related temperature rise is expected to augment diagenesis. A more realistic model of temperature rise dealing with the rate of compression of sediments that of the pore fluid(s) and the vacant pore space individually would be required.
