Investigation of an intrusion of Middle Jurassic Golden Valley showed the structure to be more complex than previously described. The intrusion appears to be located on a thrust which has brought Precambrian quartzite and schist up Ordovician conglomerate. The magnitude the movement is not easily determined' due to uncertainties concerning the thickness of the Cambrian sequence in this vicinity. The fault is considered to be a Lower Palaeozoic feature which has controlled the site of intrusion of the dolerite, possibly with concomitant Jurassic movement. The dolerite intrusion also appears to be related to a high in the Precambrian basement and possibly a Cambrian volcanic centre.
