I like the updates they made to the original design.

Looks like bivalve shells to me. The thin white curved ones are on edge, the others are parallel to the surface. They just look different depending on their orientation.

Garnet amphibolite, Gore Mountain, NY. My first ever field trip and the moment I decided to be a geologist.

Wow. What a great question. I’m going to say no. Volcanic material rises due to 1) Explosive force or 2) Convection in a rising column of ash and gas. No explosion is powerful enough to breach the upper atmosphere. Eruptive columns get closer, but eventually cool down enough to stop rising.

Amphibole in the center with pyroxene.

This is one of the thin section pictures. It had some garnets.

Who knows if it’s the same rock, but it sure does look like it.

My first thought was “I wonder if it’s from New Hampshire?”, because I collected a rock like that maybe 35 years ago. Years later, someone found another and asked what it was, so I made thin sections and had chemistry done. It was an amphibolite with a likely basaltic andesite protolith.
