Claim Text:
1. A method for validating or calibrating a sedimentary basin model by determining an age depth relationship, the method comprising: obtaining a mathematical model of a sedimentary basin plotting the age-depth relationship of rocks to be validated or calibrated, i. obtaining a porous sample of sedimentary rock from a predetermined depth, the sedimentary rock including calcite, ii. determining the geologic age of the sedimentary rock, iii. dissolving calcite from the sample of the sedimentary rock using a dilute acid, iv. determining a Ca isotope ratio of two different Ca isotopes, v. determining the age of a solution in the sedimentary rock by determining a Sr-isotope ratio of vi. determining the Ca isotopic ratio of a Bulk Solution by referencing the age of v. with known correlations or measuring the Ca isotopic ratio using Phanerozoic seawater from the pores of the sample of the sedimentary rock, vii. calculating the difference between the Ca isotope ratio step iv and step vi, viii. determining the CaCO ix. determining CaCO x. using the product of step ix to validate or calibrate the basin model.
