Exhuming my thesis, part III

Update 1: follow-on post here on the series revisiting maps or posting off-web.

Update 2: added an intriguing speculation on the adjacent Sudbury Nickel Irruptive

Following on Parts I & II here & here, here is an article on the breakup of Nuna Province in current N China: it gives new impetus to plate tectonics around 1.5GA - see Part II for another example -  such dynamic processes were proposed in my thesis paper over 40 yrs. ago here, where I applied recent plate dynamics to the Proterozoic of Southern Province of N Ontario Canada of similar age and make-up of Nuna Province. I looked at it from a structural geologic perspective, using intrusives cross-cutting relationships as date markers. The new paper actually dated similar intrusives in present day N China.

More maps, in 3D now

Update 2: found a textbook example of  "carving upstream" in this gorgeous video of the Uinta Mountains of Wyoming

Update 1: more offshore canyons crowning Antarctica found with new digital terrain data and give us a beautiful map @ bottom

This follows on the previous post here of an ongoing series of maps created for outlets that aren't necessarily on the web  - see label:revisit here and label:3D here - this is partly because I'm disengaging from socials; and that itself was partly because I had to let go of significant chunk of work on the internet for lack of resources (see §2 here). See my remaining web presence in the banner menu of the web view here.

My web footprint

Let me highlight the importance of the recent topic of AI my Community Interest Company delved into and I used in various forms shared in the last post here. Open this blog's  desktop version here, look at the stats at its right... and you'll see why the curve below spikes at far right here!
