| Abstract | The compilation of geologic exploration data from a complex Franciscan terrain near Clearlake, California, was systematized by dividing the geology into three constituent geometric systems, which are a fault system, a lithotope, and a structural vector field. It is inferred that the high heat flow is due to deep-seated magma that fed a line of cinder cones and andesite flows. The country rock of the proposed Hot Dry Rock facility will be autochthonous Franciscan metagraywackes on the south limb of the High Valley antiform. The metagraywacke ahs a foliate texture resulting in a strong mechanical axial anisotropy that caused exceptional deviation of the Audrey A-1 well. |
