I...<I>It's not just that metamorphic rocks are strong. It's that they remember. They've been through a lot - they still contain traces of their history as sedimentary rocks, sometimes in their textures, sometimes only in their chemical composition. They've been buried and heated and squashed, but they haven't succumbed to melting (or at least, not entirely). Their minerals tell the story of their burial and exhumation; their structures tell of the strains that they have endured. It's hard to tease out their stories, and much of what they experienced has been erased by more recent events. But still - these are rocks worth understanding. These are rocks with sisu.</I><BR/><BR/>Gorgeous description, of both rocks and hobbits. Why must rocks have fossils to be interesting? Fossils tell the story of life, which is very cool, but you make a great case for these rocks telling the story of the planet. Also very cool. -- Tracy :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7563205518828267408.post-29476983786342084752008-07-24T20:42:00.000-07:002008-07-24T20:42:00.000-07:00greywackes boring?!

Either way, like the metamorphic rocks recording an important history of temperature, pressure, and associated tectonic conditions, the composition of greywackes hold clues to ancient mountains that are long since gone.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7563205518828267408.post-24396104110072132182008-07-24T15:19:00.000-07:002008-07-24T15:19:00.000-07:00I just want to say thanks for a great blog!

This post really helped me to feel much more secure as an undergraduate deciding to study geology and geosciences. Your description of the rock's relationship to history rekindled exactly what originally put me in awe of the geology around us all. Thanks for a wonderful and inspiring post.<BR/><BR/>Kyle Reeves.Kylehttps://www.blogger.com/profile/07688019027018640877noreply@blogger.comtag:blogger.com,1999:blog-7563205518828267408.post-42376080587895494662008-07-24T12:52:00.000-07:002008-07-24T12:52:00.000-07:00I think metamorphic rocks are magical and gorgeous...I think metamorphic rocks are magical and gorgeous, but then I live and work on a passive continental margin, so I may be a wee bit baised.Anonymousnoreply@blogger.com
