An east-west line of section in the Rusty Ridge Quadrangle cuts across a folded

Question

An east-west line of section in the Rusty Ridge Quadrangle cuts across a folded sequence of Carboniferous strata. A portion of this line of section is shown below. In order to draw a cross section along this line, it is necessary to determine the apparent dip in the direction of the line of section and project these apparent dips onto your cross section.

a) Calculate the apparent dip in the line of section for each measurement as stations w, x, y, and z.

b) Draw a cross-section along A-A’ using the above data and projecting onto the line.

Explanation / Answer

The east - west line of section in the Rusty Ridge Quadrangle cuts across a folded sequence of Carboniferous strata.

The dip in w,x,y and z must be found out.

The apparent dip in line section of w=(60-0)=60

Dip in line section of x=(60-45)=15

Dip in line section of y=(45-30)=15

Dip in line section of z=(45-30)=15

The cross section of line from A to A' is drawn and as the dip is 15,the line is sliped according to the measurement.
