Obsession - s/t 2013. Everything gets involved.

First of all, I am sorry to post this so late. The album came out 4 month ago.
I am happy to show the world the interaction of Music and Geosciences. The Obsession's new album came out in March, 2013. I am proud to see my picture on the cover of album. I am grateful to my best friends/bandmates for their support,  for playing the music and being with me. 
Listen and download (free) music:

I would like to give a short explanation. Basically, this pegmatitic rock (microclinite) consists mostly of large (>10cm) microcline-perthite crystals. Rarely, anhedral grains of albite (not perthite) could be found embedded in microcline. On the picture you see: gray irregularly colored mass - microcline; two striped bends across the picture - perthites; black-white crystal in center - albite.

The most interesting fact is that central albite grain is, most likely, relict from alkali granite that existed here before the rock turned into microclinite. Since the relict grain is more calcic, it shows higher relief than perthite bends. More "scientific" look:

Mc-microcline, Ab8 - relict albite, Ab2-3 - perthitic albite. XPL (crossed Nicols)
The rock location: Gremyakha-Vyrmes alkaline complex (1.8 Ga), Kola peninsula, Russia

Don't let be science boring!
