dc.descriptionCemetery Ridge is a northwest-trending group of low-relief hills in a remote area in southwest Arizona. Geological mapping by Grubensky and Demsey (1991) and Gilbert and Spencer (1992) identified the basic rock types and structure of the Ridge. Haxel et al. (2015, 2018, 2021) and Jacobson et al. (2017) subsequently found that quartzofeldspathic schist at Cemetery Ridge is part of the Orocopia Schist, a Late Cretaceous low-angle subduction complex that underlies much of southern California and southwest Arizona. They also found that the Orocopia Schist at Cemetery Ridge contains tectonic blocks of oceanic peridotite, chiefly harzburgite and serpentinite, unique in southwest Arizona and probably transported from western California.en_US
