Lineament analysis of the edge-enhanced Palm Valley Landsat nw images
has defined major E-W, N-S, and a NNW-SSE, NNE-SSW conjugate set of li
neaments. Two stages of deformation are proposed to have resulted in t
he development of the Palm Valley arcuate anticline. The stage-one def
ormation, with the maximum principal stress art oriented in the N-S di
rection, generated the major gently plunging, E-W trending anticline.
The stage-two deformation, with the maximum principal stress sigma 1 o
riented in the E-T lr direction, was responsible for transforming the
gently plunging, E-W trending anticline into an arcuate anticline. The
western limb was rotated from EMI trending to WSW-ENE and the eastern
limb from E-W trending to NW-SE trending. The first-stage shear fract
ures on the convex side of the arcuate anticline were transformed into
extension fractures in this second stage. The surface and drill loggi
ng fractures study of do Rozario and Baird (1987) indicates that surfa
ce and subsurface fractures are related. Hence, the fracture system of
the Palm Valley arcuate anticline can aid subsurface gas exploration
in the area.
