Geochronology of multiple dating methods on quaternary drilling hole: a case study from Shinaimiao core in the transition zone from the eastern foothills of the Taihang Mountain to the North China Plain.

The main body of Hebi City is located in the transition zone between the mountain and the plain on the north bank of the Yellow River. It includes two major geomorphological units, the bedrock uplift area of the Taihang Mountain and the sedimentary area of the North China Plain. The Shinaimiao (SNM) core locates in Hebi City of China, belongs to the accumulation plain of the eastern foothills of the Taihang Mountains which is part of the North China Plain, and composed by quaternary alluvium and flood deposits in lithology. The SNM core is 126.64 m deep. Environmental magnetism and ESR dating method are used to divided the lower and middle Pleistocene, and determine the quaternary bottom boundary. OSL and radiocarbon (¹⁴C) dating methods are used for the division of the middle and upper Pleistocene, and Holocene. Quaternary stratum of SNM core is divided by multiple dating methods, which have provided the basic data for the study of urban active fault detection and environmental evolution in Hebi City and its vicinity.
