ABSTRACT:
The preferred geological orientation of geological formations is determined by geological measurements. These measurements are represented by original vectors which are converted into lineations which represent the extension of the vectors to their intersections with a unit sphere. One of the original vectors is designated as a reference and the half axes of all lineations within 90.degree. of the reference are selected and transformed into unit vectors. The selected unit vectors are vector averaged to produce a resultant vector and the magnitude is determined. The steps are repeated for each of the original vectors and the resultant vector having the maximum magnitude is selected as the preferred orientation of the formation.
