Main: [[Following worldbuilding tutorials]] Previous: [[Artifexian 13- (attempt 2)]] Next: [[Artifexian 15 - Island arc collisions & accreting terrain]]  ## Notes - select rift, copy geometry to digitze tool, `I` to insert verteces at start and end of line to make it into a full rift (from subduction zone to oceanic plate edge), `L`, create feature - set old failed rift to end at current date - create new failed rifts - duplicate continent, make one half, duplicate, make other half, set old continent to end at current date - make clones of ocean crust & do separate parts, change plate IDs but not dates, and then remove original ocean crust - same process for island arcs that need to be split - if subduction zone needs splitting, select, `T`, change plate IDs - decouple cratons - take the bottom entry in the plate you want to decouple, copy it, paste it above it - change the time of the pasted line to the rifting event time - change comment to "End following (craton name)" - copy that line and paste it above it - change comment of the newly pasted line to "Start moving independently" - change the last 3 digits to `000` - don't save yet, go into GPlates, go to time of rifting, `Ctrl + P`, equvalent rotations, find coords of plate you want to move - put those coords in the values for when it starts moving independently - copy that line, paste it above it, change comment to "Drift correction", set start date to `1.0` - make sure the cratons are following the correct ID on start/end, they only need new lines if moving independently - save file, refresh in GPlates, move forward 50Ma from rifting event, check using pole manipulation & highlight children - move continents (including the others) & check speeds - save everything - drift correction - save everything - fix flowlines - delete affected flowlines - go back to rifting event (for each continent?) - select rift, copy geometry to digitize tool, `M`, create feautre, flowline - add (and extend?) subduction zones at point of rifting - 50Ma step forward from point of rifting - add new ocean crust - select flowlines, digitize, `G`, add crust towards coast - add island arcs next rifting (microcontinent) - select continent, copy to digitize tool, isolate microcontinent, create feature continental crust #### My progress from last time: ![[13.gif]] added in the raster colours that I skipped over previously, this is just before splitting the left continent ![[Pasted image 20240522144452.png]] I have no idea what's going on with that middle bit of ocean crust being a lighter colour - I thought it might be some overlap but I can't seem to select anything that would be causing that 🤔 I'm not too worried about it because I don't think I'll be using the ocean crust parts visually in my end result. --- I think I made a mistake somewhere when I deleted and re-added the flowlines because this is a hot mess 😬 ![[14a.gif]] - incorrect left/right ID - right was set to 1000 instead of 900 - I think I forgot to split that rift as well when the left continent split apart ![[14b.gif]] - corrected up to 1850Ma but then something else looks like it needs splitting, looks like its between ID 100 and 300 (left continent splitting) because the ID 100 is dragging the flowlines with it - turns out I hadn't set the flowlines left/right on the bottom left continent correctly and they were at 100/900 like at the start of the simulation ![[14c.gif]] - tweaked those IDs but now the flowlines for 300/900 (pink) aren't touching the landmass properly and are overlapping it in some places 🤔 not sure what's going on there I'm going to risk leaving it as is and continue from here 🤞 I have no idea if the overlapping oceanic plates will be an issue later down the line 🙃 Next up following *this* episode and splitting off a microcontinent off the bottom right --- # 😵 I'm having fun moving the continents around but I am 100% *not* enjoying all of the faff with the flowlines, making continental crust, and remaking things all the time. My flowlines have become into a tangled spaghetti-like mess and I'm wondering if it could've been made easier with more simplified landform shapes(?) ![[14e.gif]] With all the messy layers hidden, it's looking great 😂 I'd want to continue it more though and see it through a full reformation & split again ![[Pasted image 20240522221118.png]] But with the absolute mess I've made (due to not paying close enough attention to overlapping flowlines) I'm not sure what to do next. - Attempt 3 but simpler? - or ditch GPlates and just wing it artistically? --- I think I'll try a third time but simplify things and take it slower 😅
