Numerical modeling of thermal evolution in the contact aureole of a 0.9Â m thick dolerite dike in the Jurassic siltstone section from Isle of Skye, Scotland

► Volatilization & finite-time intrusion mechanism represent natural conditions. ► Bomb geothermometer is reliable to estimate peak temperature in boiling zone. ► It is consistent with EASY%Ro to calibrate thermal history in boiling zone. ► Reliability of EASY%Ro model at contact metamorphic conditions is verified. ► Estimated TOC based on EASY%Ro model presents good agreement with measurement.
