Apatite fission track analysis was carried out to study the thermal evolution and timing of hydrogen generation in the Huahai Basin. 利用裂变径迹分析方法测量了取自花海拗陷的钻井磷灰石样品的裂变径迹年龄和长度。
Apatite fission track data suggest that the early Cretaceous strata in the Liupanshan basin were subjected to two burial heating events. 磷灰石裂变径迹研究表明，六盘山盆地白垩系地层经历两次埋深加热事件。
