Influence of lithologic erodibility on alluvial fan area, western White Mountains, California and Nevada
  • Influence of lithologic erodibility on alluvial fan area, western White Mountains, California and Nevada
  • Lithology, through its influence on sediment production, may have an important effect on the size of alluvial fans and, hence, on fan-basin morphometric relations. The purpose of this study is to evaluate the influence of lithologic erodibility
The influence of lithology on hillslope development in the area of the Jacupiranga Alkaline Complex and its surroundings (São Paulo, Brazil)
  • The influence of lithology on hillslope development in the area of the Jacupiranga Alkaline Complex and its surroundings (São Paulo, Brazil)
  • Brazil ; Cenozoic ; Climatic variation ; Lithology ; Slope ; Slope dynamics ; Slope gradient ; São Paulo ; Weathering
  • This study examines the relationship between lithology and slope form in an area characterised by a highly varied range of different rock types occurring alongside one another : the Jacupiranga Alkaline Complex. As both the tectonic evolution
  • and the sequence of palaeoclimates have probably been very similar within this small region, variations in the slope forms can be assumed to be primarily related to structural and lithological factors.
