What causes intraplate deformation in South America? Andean topography & geologic structures point to flat slab subduction, ridge subduction, tectonic inheritance. #Andes #foreland #basin #geodynamics #subduction @txgeosciences @UNLVGeoscience @TAMUArtSci https://t.co/syTmbyFcPl

what, not interested in the topic? too dry? not juicy enough?

Shallow #earthquakes in the #Andes:

🔸What's going on in #Ecuador?? 😬
🔸Hints at #SlipPartitioning in the north and south. 🥰
🔸Northern #Peru is awfully quiet! And also seem to have been cheated out of its rightful share of #volcanoes. 🤨

Any geoscience/hydrology scientific illustrators out there? Might have funding to help me build educational content for the citizens of New Mexico all about water resources! DM me if interested!

Check out the hairpin turns in the Uraricoera and Takutu rivers in the northern Amazonian state of Roraima. These rivers formerly drained north into Guyana and now drain south into the Branco and then Negro rivers.

I like making big blue maps of remote places. Here's my latest: https://t.co/9OjONTDuEA

Pedro Val (@topoerosion) liked studying geology. But when he learned about how tectonic activity can change the flow of rivers, he “didn’t want to know about anything else.” @theAGU

Halgurd mountain (3607 m; 11834 ft) a stacking pile of pillow lava basalts! Once upon a time a newly formed Neotethys oceanic crust between the Eurasian plate and the Arabian plate, now the highest peak of the Zagros mountain range in the Kurdistan region of Iraq! @InsideNatGeo

River drainage networks of England show the effects of both tectonics and erosion, with many smaller basins draining to the periphery, but the development of some larger interior basins by river capture, as in the Trent and Severn basins.

Also environmental conditions in the past. Nothing in the Amazon makes sense except in light of the Pebas megawetlands that covered over 1 million sq km from 22-10 million years ago.
