🚨PAPER ALERT🚨

This is a #serpentinite #shearzone.
It is part of a #subduction complex where oceanic serpentinites were subducted, sheared, carbonated, exhumed, and coupled with sediments that we recently described on the Island of Elba, Italy. A 3ad

The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku.

How is your day going? Today I have found the first record of #Argiope trifasciata from #Tuscany, close to where I live. This #spider likes arid environments and it is spreading north as the #climate warms. Closest observations to this one are from Corsica, Sardinia and Naples. 🕷️🦋 #nature

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.

Yokonami melange, a paleo-megathrust, and so, so much chert, near Kure, Shikoku Island, Japan
Two geologists pointing out enormous coastal outcrops of steeply-dipping ribbon chert. Closer view of the folded and steeply dipping cherts, with two geologists standing on outcrop. Down-looking view of block-in-matrix melange of scaly mudstones with sandstone blocks. Outcrop photo of brittle fault rocks at the top of the Yokonami melange, with pencil for scale. This has been interpreted as a fossil plate boundary fault zone.

On the left, "tsunamiman and jishinman", the villains of our story (jishin = earthquake in Japanese)

Mind blowing rocks of Rosso Levanto: mantle peridototes that were carbonated and then weathered on the ocean floor of the Piemont-Ligiria ocean.

There's truly no shortage of stunning leaf-footed bugs. This species is Pachylis laticornis!

Just deleted my science twitter and made a bsky... My feed was getting full of crazy stuff, and I pretty much just want to see things about rocks, earthquakes, and fluffy dogs/cats.

One of the samples that I was working on today, a hefty slab of "Duke Stone" metaignimbrite from the Piedmont of North Carolina. This is the rock that was used to build the Gothic architecture of Duke University. Made in a pre-Appalachian volcanic eruption, it got squeezed as Pangaea was assembled.⚒️
