Halloween in Kilkee

Staurolite is a regional metamorphic mineral of intermediate to high grade. It occurs with almandine garnet, micas, kyanite; as well as albite, biotite, and sillimanite in gneiss and schist of regional metamorphic rocks. A special property of staurolite is that it often occurs twinned in a characteristic cross-shape. In handsamples, macroscopically visible staurolite crystals are of prismatic shape. They are often larger than the surrounding minerals and are then called porphyroblasts.

Ellie and I have been asked a whole bunch of times if we're sisters, and sometimes if we're twins, so we decided to go as twins for Halloween. Then we found out we were going to be on a geology field trip, so naturally, we HAD to do a geology themed costume.

The actual mineral staurolite.
