Porwaki koło Wlenia nature reserve. Pogórze Izerskie. Cretaceous sandstone xenoliths in a former tertiary volcanic chimney, crystallized into the columnar joint. Basically it's a sandstone of a basalt-like appearance. Some of the xenoliths retained their former structure.

Matilijas at la Madre Grande. #Romneya sp.. I don’t know how to tell R. trichocalyx and R. coulteri apart from the seed pods. But they’re both #matilijapoppy, which look like big sunny-side-up eggs when in bloom. The rock formations here are beautiful. I’m sure that they must have had some significance to the ancient Kumeyaay. I know that there’s a peak relatively nearby that plays an important role in a solstice ritual that people still participate in to this day. I think this one rock has some #xenoliths in it? #jamulca #kumeyaayland (at Jamul, California) https://www.instagram.com/p/CUYPB4VLnIC/?utm_medium=tumblr

I have accumulated a decent collection of rocks so far in my time as a geology student!

The photo quality is going to be awful, and I'll probably make a new post when I get home for the summer and have a decent camera.

I collected several xenoliths during my trip to Hawaii with one of my professors! They all show different percentages and sizes of olivine, though I haven't had an opportunity yet to study them in a lab setting.
