Chronology of periglacial structures in Northern China
Abstract Structures of assumed periglacial significance in Northern China include (1) ice‐wedge casts, (2) frost cracks and (3) involutions. On the basis of involutions and palynological analyses, the earliest period of periglacial conditions (Nangou Periglacial Stage) occurred 2.5‐3.15 × 10 6 years...
