  1. Laterite (Pedology 🟤)

    Laterite is a soil type rich in iron and aluminum that often forms in hot, wet areas; most such soil is found in the tropics. Nearly all laterites are of rusty-red coloration due to high iron oxide content. Laterite soils develop by intensive and prolonged weathering of the underlying parent rock, usually under conditions of high temperatures and heavy rainfall...

  2. Unravelling The Dance Of Earthquakes - Evidence Of Partial Synchronization Of The Northern San Andreas Fault And Cascadia Megathrust

    “Previous paleoseismic work has suggested a possible stress triggering relationship between the Cascadia subduction zone and the northern San Andreas fault based on similar event timings. Turbidite successions correlated to both systems may support this hypothesis. Historic earthquakes in 1980 and 1992 in the Cascadia subduction zone and the 1906 earthquake on the northern San Andreas fault left turbidite records that are temporally well constrained by bomb-carbon−supported age-depth models..."

  3. Soft sediment folds for #FoldFriday These gorgeous blocks of downslope slump folds, with a syn-sedimentary, mini erosive unconformity above, are from the Upper Ordovician Ardwell Farm Formation, exposed on the shore south of #Girvan. #Hunterian museum collections. #Geology #Sedimentology #FridayFold
