OK petrologists, this is probably the most interesting outcrop I've been to. Calling it 'tire tread' texture. Reminds me of the doublets at Stillwater. Oblique to quartzite contact to the left and main body of gabbro to the right. Didn't even stop for #geologylunch. @EnvUoA

Not sure if anyone I know is still on Twitter/X but I'm moving to bluesky. Find me there @cutenzrockguy.bsky.social

@nz_stroms @NZSeds @EnvUoA Driving the electric car, I couldn't even rev the engine a bit to get the horses to move.

Five years of planning and IAVCEI 2021...2023 is finally over!

[Michael Rowe @mcrowerocks]

Great to see our students @tuff_bickies and thomas stolberger getting credit for new discoveries. Even if @GeoscienceNZ president can't pronounce the species names! @EnvUoA

[Michael Rowe @mcrowerocks]

Congratulations @NZSeds for winning the prestigious GSNZ Hochstettler lecturer award. Very well deserved, we can't wait to hear about your submarine landslide work! @EnvUoA

1st day of our fieldtrip as part of the LifeSprings Mars sample return mission planning meeting. Looking at various terrestrial samples of digitate sinter. Wai-O-Tapu champagne pool. @EnvUoA

Congratulations @ShreyaKanakiya on getting the last chapter of your PhD published (far more efficient than I was(am?)!) @EnvUoA

@eruptionsblog @AEGFergason I'd definitely be in the 5th category, I have trouble keeping up with the limited social media platforms that I already manage

[Michael Rowe @mcrowerocks]

@eruptionsblog Wouldn't you want to know what it said BEFORE you purchased it?

[Michael Rowe @mcrowerocks]

It is always great to see a Masters student translate their thesis to a publication- it doesn't happen for everyone so well done @tuff_bickies. Also loving Oxford Uni Press's new open access agreements with NZ Universities. @EnvUoA

Congratulations Jie Wu. Final PhD chapter is now out, open access. https://t.co/g1kyCdqbkA

Now I need to find a new project in the Jemez Mountains...

@janinekrippner It's so much better than someone throwing gravel at you.

My final Chilean edition #geologylunch is a reminder to always watch for crossing alpacas.

[Michael Rowe @mcrowerocks]

@GeophysicsWebb @fracturedfola @EnvUoA Yes it has a strong cumulate texture. Just a very odd orientation and dimensions with respect to the gabbro.

[Michael Rowe @mcrowerocks]

@FaithfullJohn @EnvUoA It's continuous with the gabbro although there are discrete feldspathic and amphiobole rich domains bounding between it and the main gabbro body. There is a clear physical boundary at the other contact eith the quartzite so I'd say it is part of the gabbro.

[Michael Rowe @mcrowerocks]

More fun with dikes (diorite this time) intruding black Devonian to Carboniferous metasediments. PhD student Eduardo and field assistant Marcelo for scale. @TectonoFluids @EnvUoA

[Michael Rowe @mcrowerocks]

@klksnow @TectonoFluids Yes you can take orientations of the planes of the feldspathic 'treads' and they seem to remain relatively constant (at least up the outcrop in photo- measurements get harder as the outcrop gets higher).

[Michael Rowe @mcrowerocks]

@klksnow @TectonoFluids I should also say it extends about 20 to 30 m uphill, well past the more feldspathic texture that is immediately adjacent to it (which pinches out near to top of the image)

[Michael Rowe @mcrowerocks]

@tacinellijohn @EnvUoA Good question. There is no evidence that it is physically distinguishable from the larger gabbro body even though it looks very dike like.
