Question

Boreholes were drilled at A, B, C and D which
are at the corners of a rectangle, whose
sides are 1000 m. and 1500 m. The 1000 m.
sides are parallel to E-W line. A is at NW, B is
at NE, C is at SE and D is at SW corners
respectively. A limestone bed was reached
in the boreholes at the following depths, at B
700 m., at C 400 m., and at D 700 m. Find
the strike direction, dip direction and dip
amount of the limestone bed. Also find at
what depth the limestone bed be met A.​

Answer 1

Explanation:

Boreholes were drilled at A, B, C and D which

are at the corners of a rectangle, whose

sides are 1000 m. and 1500 m. The 1000 m.

sides are parallel to E-W line. A is at NW, B is

at NE, C is at SE and D is at SW corners

respectively. A limestone bed was reached

in the boreholes at the following depths, at B

700 m., at C 400 m., and at D 700 m. Find

the strike direction, dip direction and dip

amount of the limestone bed. Also find at

what depth the limestone bed be met A.
