Geologists love interesting rocks. Blueschists have always been one of my favorite rocks. Unique and odd mineralogy, interesting metamorphic history - evidence of low-temp and very high pressures. Such a unique environment, and from subduction zones, easily one of the most unique environments on the planet. Whats not to like?
Just brought back a nice wee bit of phyllite from my trip through the Cévennes (French Massif Central) in footsteps of Robert Louis Stevenson. Default rock is metasediment schist, basement of the former Hyrcanian mountain range; also granite known in French as 'horse tooth granite " for its centimetre size feldspar crystals.
