Abstract (751) HTML (233) PDF (5295KB)(83)
Abstract:
The Qilian Mountains are situated on the northeastern margin of the Tibetan Plateau and serve as the leading edge of the plateau's northeastward expansion. The Menyuan Basin, characterized by typical basin landforms, provides valuable insights into the region's neotectonic activity and geomorphic ev...
Quantitative staging of alluvial fan geomorphic surfaces in arid areas based on SAR imagery: A case study of the Shule River alluvial fan in the western desert region of the Hexi Corridor
YANG Yongzhong, REN Junjie, LI Dongchen
2023, 29(6): 842-855. doi: 10.12090/j.issn.1006-6616.2023080
Abstract (545) HTML (137) PDF (6361KB)(27)
Abstract:
The alluvial fans and river terraces formed by river processes effectively record past tectonic activities, climate changes, and geomorphic evolution processes. Accurately dividing the alluvial fan into stages is the basis for the subsequent research. Previous researchers used L-band SAR backscatter...
Evolution of sedimentary environment at the ZKA01 borehole in the north wing of the Yangtze River Delta since late Quaternary
LIU Xianguang, YANG Jinwei, JIANG Ren, LIANG Feigang, XIA Bin, WANG Ju, HU Li, SUN Fengrui, DONG Junlin

Abstract (606) HTML (211) PDF (3677KB)(34)
Abstract:
The late Quaternary chronostratigraphic framework and marine transgression have long been research focal points in the Yangtze River Delta. The frequent channel oscillation and river incision in the Yangtze Delta have led to the frequent absence of complete stratigraphic records. Complete marine tra...
