Presentation Transcript

  1. Erosion, Weathering and Regolith Development Cliff Riebe, Jesse Hahm, Heather Rogers & Steve Holbrook

  2. Altitudinal variations in vegetation Alpine slopes Lake Tahoe Sierra Nevada Dense conifer forests San Francisco Mountains 85 km Fresno Las Vegas Oak woodlands Pacific Ocean

  3. However, altitudinal variations in climate do not explain everything! Bald Mountain Southern Sierra CZO catchments

  4. Holbrook et al. in revision Important for understanding: • water cycle • soil-water storage • timing & amount of melt runoff • pedogenesis • weathering, erosion and landscape evolution What controls the presence/absence and thickness of regolith?

  5. Influence of geology on vegetation: Bulk geochemistry, including bedrock P

  6. Influence of geology on vegetation: Mineralogy?
