* How to reconstruct the pattern of strike of the rock layering pattern is as follows: plot the data needed; create key strike/dip contour; reconstructs the geological structure if any; and reconstructs the pattern of strike and dip.

Three main elements are commonly found in a geological map is Map Units, Contacts and faults, Strike and Dip.

'''Map Units''' show different from rock type and other earth materials,showing with the specific color and symbol.

'''Contacts''' between two maps showing where the different units of the types of rocks bordering the other rock types.If the border is cear, it will be showing with a thick line,but If the border is uncertain, only showing by the dotted line.

'''Faults''' is the location where there is a transfer plate, on a geological maps, the fault line indicates where an experienced unit slid, pushed up or dropped down relative to the binder adjacent units.

'''Strike and Dip'''  symbols show the orientation of rocks to the field of fracture. Long lines show the strike, and the short line is dip. Dip is usually also accompanied by a number and direction, which shows how much the angle of outcrop of rock.
