What reading level is Geology book?
To quickly assess the difficulty of the text, read a short excerpt:
Vertical face of rock, such a. S a cliff or the wall of a quarry ; but in such a case, in order to determine its full amount, it is necessary that the face Displacement of Rocks.
463 should be, like AOD (fig. 131), perpendicular to the strike; if for instance a measurement was made on faces such as ABO, A CO, the observed angles would be less than the full amount of the dip.
In practice it often happens that we cannot find a vertical face run- ning along the full dip, but we can generally get m...easurements of the apparent dip along two faces making a large angle with one another, from which the amount and direction of the full dip may be determined either by the formula given in the note below, * or by the following graphical method.
Let OA, OB be the bearings of the two faces on which dips are measured, and let the dip along OA be 1 in m, along OB 1 in n. Take in OA Oa = m, and in OB Ob = n: join ab, and draw OC per- pendicular to ab. Then OC is the direction of the full dip, and the amount of the full dip is 1 in OC.
