Abstract (in english)
   Two old basic graphical methods of paleostress reconstructions include right dihedra method (Angelier - Mechler 1977) and M-plane method (Arthaud 1969). These two methods are two marginal cases of general inverse method based on one-fault inverse analysis. using fault coordinate system, where l-axis is stria lineation, n-axis is normal to fault plane and m-axis complete right-hand orthogonal system 1mn, it is easy to derive equation for Lode parameter u1= (2 - -)/( - ) in dependence on direction of and respectively. This function limits field of possible directions ith decreasing of u L max (Fig.2a) and -field with increasing of u Lmin. The field of is equivalent to right dihedra quadrant for u 1 as one extremen and it is reduced to part of M-plane for u=-1 as the second extreme (Fig.1). Base on it we can make equal-area plot for field of and with isolines of (Fig.2b, c).
   With these plots we can determine upper and lower limits of u (uLmax, uLmin), and corresponding fields of and respectively.
