Call for Posts: Accretionary Wedge #42 – Countertop Geology

January 10, 2012 in Accretionary Wedge

Ok, folks.  This is my first time hosting the Accretionary Wedge and I plan on making it memorable.  One lucky entrant (chosen at random) will receive a special geologic prize pack containing one volcanic bomb, one piece of mantle peridotite, one piece of fresh Pennsylvania anthracite, one rough diamond cube, one vial of ash from the 1980 eruption of Mt. St. Helens, one vial of ash from the 640 ka eruption of Yellowstone collected myself in southern Utah, a piece of garnet amphibolite from the Barton garnet mine where the amphiboles actually steak the show from the garnets, and whatever else I decide to throw in there.  All you have to do is post a wedge entry on your own blog or send it to me and I’ll post it for you.  Either way, you’re automatically entered.

AW #42 Call for Entries: Countertop Geology

Have you seen a great countertop out there?  Sure, everyone says it’s “granite”, but you know better.  Take a picture, post it on your own blog or send it to me and I’ll post it for you.  Do you think you know what it is or how it was formed?  Feel free to include your own interpretation and I’m sure others will enjoy joining in the discussion.  Ron Schott suggested that we expand the entries by including any decorative stone material that has been separated by humans from it’s source.  This includes buildings, statues, etc.  There’s a lot of really unusual stuff out there, so make sure to find a good one.  The deadline will be the end of January, but I’ll be posting entries as they come in.

A few months ago, I took a picture (above) of a countertop in a New Jersey restaurant and posted it to Twitter (@volcanoclast).  I spend a lot of time examining countertops, stone walls, stone statues, and pretty much any object made of stone and I love that the material has been transported from Who-Knows-Where and is completely detached from any in situ clues to its provenance.  You could be in the NJTransit area of New York’s Penn Station and staring at pink fossiliferous Italian limestone that has no business being there (really, it’s beautiful).

With the proliferation of stone countertops, this topic is open to anyone with a curious mind and thing for rocks.  That’s what makes this such a great topic for the Accretionary Wedge.  Even people who have no idea what they’re looking at, still know a beautiful rock when they see one.  If you’ve never participated in an Accretionary Wedge before, this is your chance.

Anyone can enter, so professors, get your students involved!  Let’s make this this biggest Accretionary Wedge ever!

I’ve got a great countertop in mind for my entry, so stay tuned…
