RULE OF ‘V’s

RULES OF‘Vs Traces of dipping layers (a) that intersect uneven ground or 'topography (b) Left hand side: Map view of layer in stream valley. Right hand side: cross c section view of dipping layer (after Marshak and mitra laboratory manual)

RULES OF ‘V’s Traces of dipping layers that intersect uneven ground or ‘topography’. Left hand side: Map view of layer in stream valley. Right hand side: Cross section view of dipping layer. (after Marshak and Mitra laboratory manual.)

Outcrop patterns illustrating the rule of Vs: (a) horizontal layer,(b) layer dipping upstream (c) vertical layer

Outcrop patterns illustrating the rule of V’s: (a) horizontal layer, (b) layer dipping upstream, (c) vertical layer
