Illustration of turbidite formation. Turbidites
form when terrestrial sediments tumble from the top of
the steep continental slope into deep water in a densitydriven underwater landslide. Turbidites would eventually
lithify into the graywacke and shale of the Franciscan
Complex. Turbidites typically display a fining-upward
sequence known as graded bedding.
