Think I got the coolest birthday present ever! 😍☄️ #pallasite #meteorite #teamolivine #outofthisworld #thinsectionmaybe?

Snow day = grain picking day

Our SEG Student Chapter is extremely thankful for all the support and mentorship Roger Morton has given our economic geology students. If you'd like to attend his Celebration of Life, please see the info in the link - UofA SEG student executive committee. edmontonjournal.remembering.ca/obituary/roger…

Fancy a whisky drink with some Acasta “gneiss” cubes? ⛏🥃#oldestwhiskystones #geologylife #writingmythesisnow...

Successful mineral auction this year. All those hours making coasters and whisky ice cubes paid off... #mineralcollectors #geologistlife

My contribution to #ThinSectionThursday shows garnet rims forming between clinopyroxene and plagioclase, while garnet is also breaking down to spinel. Orthopyroxene (containing garnet exsolution) is also surrounded by this corona of clinopyroxene and garnet. Lots going on!

Back to wearing clean lab suits again...this time to see the Apollo sample collection (all organised by mission number). Very, very cool! Did the old microscope trick to get a better view of the troctolite. #satisfiedgeologist ⛏#explorationinterns #lunarscience #mineralogy

Before going to space, Astronauts go to geology camp! Geology helps us discover information about the early history of the Moon, Earth, and inner solar system. Studying rock and soil samples from the Moon & Mars will be crucial in our journey of human space exploration. #Artemis

Preparing some jadeite and eclogite samples for my undergrad student. Neat little BSc project!

Throwback to “peridotite peak” - part of the ophiolite complex in northern British Columbia. You might be able to spot it on Google Earth! Sad to miss out on field season this year but I’m looking forward to Fiji and Greenland next year! #GeologistsDay #StayAtHome

Stony-irons are mixtures of metal & silicate rock. Most beautiful are pallasites, with green olivine (peridot) crystals in metal matrix. Their origin is highly debated. Maybe they come from core-mantle interface of a differentiated asteroid, maybe they form by asteroid impacts
