These curves can serve as a guide when choosing a combination of points that is advantageous for direct intersection, and in this regard, they seem to be more rational than those shown in the diagram, 2 curves of equal accuracy. The latter curves retain their value for graphical or mechanical balancing of the position of a point determined from more than two points. In this case, using these curves, we can easily determine all the definitions of a point corresponding to a given combination and can take it into account when deriving the balanced value of the coordinates of the latter.
Recently there has been some revival in the literature on faults and other displacements of layers and veins, and this revival concerns even the purely geometric side of the issue, which seemed to be completely exhausted. We propose another conclusion of crossings and from them faults, re-faults and other displacements, in which these latter are arranged in a row in decreasing or increasing order of the formation doublings present in them, from which, as a consequence, follows the determination of the shortest and most convenient routes for exploration of the dropped part of the formation. Along the way, we will have to touch on the modern, extremely imperfect in the geometric sense, terminology and classification of faults and other displacements."
