My office has become very big and breezy this week, with more cavorting fighter jets than usual. Spectacular #geology in the lake district. #fieldwork

If you're at #EGU and interested in hearing what #autistic students have to say to you about #geoscience #education and #inclusion, we'll be sharing their voices on Thursday (1st May) at 12:10-12:20 CEST in Room 2.21.

Olivine olivine, and some more olivine in a peridotite.

A nice transition from katophorite (brown) into ferro-eckermannite (blue) and then aegirine (green) in the interstitial space of a peralkaline syenite

A nice schist with muscovite, kyanite/sillimanite, chlorite, and twinned plagioclase.

A relict olivine crystal being insidiously replaced by serpentine in a forsterite-diopside marble.

Tried a diff. approach w/ PPT slides this year. Rather than slide numbers, the slides transition from morning through to evening to indicate progression, with diff. animals throughout.

Gives the chance to sneak one easter egg into each lecture too.

Clinopyroxene, plagioclase, and abundant leucite (hiding in plain sight) in a tephritic lava from Vesuvius, Italy

A coarse grained, amphibole-bearing glomerocryst (right) contrasted against crystal-rich, porphyritic basaltic andesite (left).

Aegirine in a peralkaline syenite from the Azores.

The darker patch in the middle (and the crystal above) is ferro-eckermannite or arfvedsonite, a Na-rich amphibole.

The surrounding grey crystals are a cumulus framework of alkali feldspar.

Interlocking olivine, clinopyroxene, and plagioclase feldspar in a relatively pristine gabbro.

FoV = 2.5 x 1.5 cm

I used to do this somewhere else: a nice contact between coarse agpaitic syenite and finer grained metaluminous syenite.

The latter includes a mixed mineral assemblage with forsterite and diopside derived from mixing with hawaiitic magmas.
