Kinetic effect of heating rate on the thermal maturity of carbonaceous material as an indicator of frictional heat during earthquakes

摘要: Because the maximum temperature reached in slip zone is significant information for understanding behaviors during an earthquake, maturity of carbonaceous material (CM) widely used as a proxy detecting frictional heat recorded by fault rocks. The degree maturation CM controlled not only but also heating rate. Nevertheless, has been estimated previously comparing natural rocks with that synthetic products heated at rates about 1 °C s−1, even though this rate much lower than actual earthquake. In study, we investigated kinetic effect on process performing organochemical analyses slow (1 °C s−1) and fast (100 °C s−1) rates. results clearly showed higher can inhibit reactions CM; example, extinction aliphatic hydrocarbon chains occurred 600 °C 1 °C s−1 900 °C 100 °C s−1. However, shear-enhanced mechanochemical effects promote may offset high We should thus consider simultaneously both mechanochemistry to establish more rigorous estimating
