Back on Oʻahu and Big Island in late January and super excited to get to (re)visit mantle and crustal xenoliths of the Koʻolau Honolulu Volcanics as well as those of Hualālai, Mauna Kea, and unusual Mauna Loa ultramafic mantle xenoliths hosted by tholeiitic basalt.

Kilbourne Hole peridotite mantle xenolith with area of dark orthopyroxene crystals formed via the rock-melt reaction MG2Si04 + Si02 → 2MgSi03. Part of a complex history involving rock-melt interaction, refertilization, and multiple metasomatic events.

I started some chibis of my favorite Disgaea characters around halloween. But I never got around to finishing a whole batch till now! I very much treasure these goobers (❁´◡`❁)

Here's another one, but in this case the xenolith of peridotite smushed the anorthosite xenolith underneath it.

Fun igneous geology: here's a rigid xenolith of peridotite in gabbro, with a less rigid xenolith of anorthosite that was smushed on top of it as the mushy pile of partially molten gabbro compacted under its own weight. On Sgurr na Stri, Isle of Skye, in the Scottish Highlands.

She'd let her guard down. This was a totally unusual feeling. She hadn't thought of him in well, centuries. Xenolith.
Some things are forgotten for a reason.
She ignored all the mystery around her. She would gaze longingly at the sea, just...
The ocean. That's all she needed.

The results are in, and the people have spoken: Xenolith is a pretty neat idea.
And what's more, it's an idea with plenty of potential still untapped... so we're going to get tapping. Feel free to follow if you'd like to hear about that when it happens!

X is for Xenolith, stone within stone. What essence remains when we’re no more than bones?

Olivine is my second fav mineral after pyropic garnet and am super loving this forsteritic olivine ring. Peridotite xenolith in phonotephrite is from the classic location of the San Carlos volcanic field.

There is also a clinopyroxene xenocryst to the left of the xenolith. eruptions here were phreatomagmatic and thus highly explosive. Plant fossils preserved in the tuff are often so well preserved we can identify them down to the species.

My entry to the #LudumDare58 Compo is now up! In Xenolith, you must pick up the baton from those who played the game before you, and make a little progress before you hand over the reins yourself...
Because the game only lets you play it once.

This is one of the dykes found near Ayer's Cliff, just SE of Magog, Quebec. It's a set of three dykes, one of which has the deep-derived xenoliths. That one dyke has weathered much faster, perhaps due to a higher carbonate content.

I was a field and lab geologist at the USGS. I have mine, too, in case anyone needs to know the source of that carbonate xenolith we found in a Montana diatreme almost 50 years ago.

looks a bit like a xenolith or a dike/sill, an inclusion of something much more mafic than the paler host rock maybe? it *looks* like there're even a couple of chunks of the host rock pulled into the darker mass, something common with injections or sills. Neat looking!
