By the end of this section you should be able
to draw the outcrop pattern
and topographic pattern of:
Horizontal beds
Vertical beds
Downstream dipping beds
Upstream dipping beds
and topographic pattern of:
Horizontal beds
Vertical beds
Downstream dipping beds
Upstream dipping beds
This presentation is to be completed in conjunction with exercise sheet 1.

Слайд 3 The Law of “V’s”!
V-outcrop patterns can be used to
deduce the dip direction of inclined strata and estimate the amount of dip.
Beds dipping downstream V-downstream
Beds dipping upstream V-upstream
Beds dipping downstream V-downstream
Beds dipping upstream V-upstream
School of Earth and Environment
Слайд 4The Law of “V’s”!
Outcrops of horizontal beds will always appear
parallel to contour lines.
Outcrops of vertical beds will always parallel the direction of strike, regardless of terrain.
e.g. vertical dike intruded into older strata
Vertical structures are usually easy to spot on satellite imagery, air photos

If you are finding it hard to visualise the concepts covered in this exercise then:
Review the explanations at the beginning of the exercise.
Also have a go at building the 3 dimensional model of V-outcrops on the following slide and included at the back of the worksheet.
