The pillow rinds have preferentially weathered, outlining the basalt pillows formed at least 3.75 and perhaps as long ago as 4.3 billion years ago. Now metamorphosed to amphibolite grade. In the Ujaraaluk unit of the Nuvvuagittuq Greenstone Belt, near #Inukjuak, northern #Quebec. #McGill University #EarthSystemScience #PillowBasalt #Hadean 1/2

Cambrian Potsdam sandstone exposed at Pointe du Buisson, on the south shore of the St. Lawrence near Montreal. The sandy veins cross-cutting bedding have been interpreted as Seismites that record earthquake shaking and soft sediment deformation 500 million years ago. What do you see, @keepitrheol ?

Dee Gardner @glacierpique.bsky.social“They were able to identify the presence of two rather unique crystals on the surface of washed rind cheeses: struvite and ikaite.”

#Leucite is used to make dental porcelain (or rather, leucite + glass from melting feldspar incongruently). Thiis is becuase it:
is immune system compatible
is machinable
is fracture resistant with low porosity
it doesn't easily stain or discolour
and most importantly, its thermal expansion matches the metal anchorImage from: J.R. Mackert et al (1986)The effect of the leucite transformation on dental porcelain expansion, Dental Materials 2: 32-36

Congratulations to Dr. Keavin Moore, who successfully defended his PhD thesis, "Coupled Models of Water on Terrestrial Planets Orbiting M-Dwarfs"
(supervised by Nic Cowan)Keavin's models predict that water dissolved in a magma ocean, combined with recycling hydrated crust back into the mantle, can both limit water loss during the early active phase of a red dwarf star.
