I've spent very little time there, unfortunately, but last year I made a point of driving through the purple patch on that map, which is the largest exposure of peridotite in the 48 states, if not North America. I came home with some nice samples <a href="http://geology.about.com/od/more_igrocks/ig/peridotite/" rel="nofollow">and photos</a>.Andrew Alden, Oakland Geology bloghttps://www.blogger.com/profile/17369367151045054784noreply@blogger.comtag:blogger.com,1999:blog-5211670216140060946.post-61613530487895407802010-02-24T20:08:46.699-08:002010-02-24T20:08:46.699-08:00California really is a geologic mess, along with S...California really is a geologic mess, along with SW Oregon's Siskyous which run east and west and share some of the same marble found in Kings Canyon/Sequoia.

But when my apt. flooded a few years ago, I lost all of my undergrad notes and texts, along with all my slides.<br /><br />Still, I can offer one anecdote: On a trip with Jad D'Allura from SOU (Ashland) we made a stop along the Klamath River. In one ~50 yard outrop, we saw a talc-chrysotile schist (peridotite parent), a felted amphibolite (basalt parent), and bedded cherts. That group was probably originally one broken chunk of sea floor. The next block contained mica schist and blocky beds of wollastonite, probably a carbonate shelf and shale facies. The third block was a somewhat metamorphosed turbidite series. To see all of these environments represented in 50 yards is hard to conceive.Lockwoodhttps://www.blogger.com/profile/05960762797349483760noreply@blogger.com
