摘要:

磷灰石、锆石裂变径迹分析资料表明沁水盆地在26.2~11.5Ma前发生过一次抬升冷却事件,具有盆地南、北部抬升冷却早,中部抬升冷却晚的特点,渐新世—中新世的抬升冷却与青藏高原在新近纪的大规模隆升有关。新生代渐新世—中新世发生大规模抬升冷却,地层温度降低,石炭-二叠纪煤系地层生烃过程停止。

关键词: 沁水盆地, 构造热事件, 冷却事件, 裂变径迹

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
