Abstract:

ission-track analyses of apatite and zircon show that an uplift-cooling event occurred in Qinshui basin 26.2-11.5Ma ago. It occurred earlier in the northern and southern parts, and later in the central part. Qinshui basin experienced a large uplift-cooling event from Oligocene to Miocene, as a result, the formation temperature decreased and the hydrocarbon generating process in the Permo-Carboniferous coal measure strata ceased.

Key words: Qinshui basin, tectonic-thermal event, cooling event, fission track
