Abstract

On the calculation of the thickness of inclined strata.

1.	The curve in Fig. 2, constructed from Fig. 1, gives the thickness, at any angle, of dipping strata between two points, whose distance is 100 in the direction of maximum slope.
2.	When the rock is only uncovered in narrow sections (such as in shore lines, rivers, etc.) these, as a rule, run in another direction than that of the dip. If the horizontal line in Fig. 2 represents the angle between the strike and the section, the vertical column gives the a mount of dip along the section, in percentage of that in the direction of maximum slope.
3.	The actual thickness of dipping strata in drilling cores is also obtainable from Fig. 2. Here the horizontal line assigns the angle between the bore hole and the strata.
