RE:RE:RE:RE:RE:RE:RE:RE:Keats OzMegacopper, my theory is that because of the shallow dipping westerly Grub Line thrust fault, other structural events were happening in the hanging wall (upper layer), opening up and creating near vertical normal faults like the Appleton and JPB faults. With more movements on the thrust fault, additional splay (crosscutting) faults were developed between the Appleton and JPB faults. How's that retiredgeo? not perfect, but close?
