The two-circle contact goniometer was devised to supplement the two-circle reflecting goniometer, by furnishing a means for the measurement of medium-sized crystals not provided with sufficiently good reflecting faces for the successful use of the latter instrument. The contact goniometer has however proved itself adapted, in a greater degree even...

New graphic methods for determining the depth and thickness of strata and the projection of dip
Harold S. Palmer
1919, Professional Paper 120-G
Geologists, both in the field and in the office, frequently encounter trigonometric problems the solution of which, though simple enough, is somewhat laborious by the use of trigonometric and logarithmic tables. Charts, tables, and diagrams of various types for facilitating the computations have been published, and a new method may...
