Friday Rock Blogging: Aplite Dike
- Lovely, but mundane, mottled granodiorite forms.
- Equally lovely pale aplite (quartz+feldspar) muscles its way into a weak spot.
- Stripe!
- Broken stripe! Awesome!
Also, Joe has a Thursday Rock Blog up. (Update: also Kim!) The bandwagon, she lumbers along…

Thanks for the Shout out! your the first person to ever acknowledge my blog (except for my friend jay who wrote an email to all my friends called me a “jerk”).
BTW…ain’t nothing like a cross cutting relationship between some dikes and some intrusives to make you imagine the outcrop’s geologic history…
