Geological History Draft

[MysteryMan23]

Okay, so I've been working on my planet's geological history for a while, and I've come up with a rough draft of sorts. Now, I'm not certain if this is really what I want to go with; there may be major flaws I haven't spotted, and I really want to make sure I have a good foundation for my map before I continue with it.

My main concerns are with the peninsulas that attach themselves to the pink continent. Do they move realistically? And are there any other problems that you can notice? Thanks.

Wow, that image is pretty cool. The green and gray peninsulas should be fine, though the green one would probably dig itself into the pink elephant a little more, like India into Asia. The blue one, I'm not sure of. It looks a little small, but I don't know whether that actually matters or not.

[MysteryMan23]

Thank you, Matrix.

Does anyone else have any input? If not, I'm sticking with this as the basis of my map going forward.

I liked how the projection distorted the image, so we know you're thinking about it in spherical terms. I had a hard time trying to figure out exactly where the divergent fault lines were, though, at least in the north. The red continent changes direction; is that because a new subduction zone started to the south, or a new divergent plate boundary opened up in the northern ocean? Also, what happens to the plate that's between the yellow and blue continents? Is it being subducted on all sides, or is it bisected by another plate boundary?

@Hydroeccentricity: Thanks for the compliment. I actually made a point of making sure my tectonic history occurred on a sphere, even though I needed a special program (which ended up being gplates) in order to get anywhere with that.

I honestly think it's more likely that a new divergent plate boundary opened in the northernmost ocean, which caused downward motion in both the red continent and the pink continent. As for the "yellow and blue" continents, I'm not sure which ones you mean. I assume the "yellow continent" is the one that ends up in the south-west part of the map. If so, then the only other shapes on the map that come close to being blue are the tiny cyan one and the bigger greyish one. Both remain quite a ways away from the yellow continent most of the time, so I'm really not sure what you're referring to.

@Matrix: My general idea was that mountains formed between the green peninsula and the rest of the continent as their continental shelves collided. Same deal with the little cyan peninsula. In fact, much the same happened with the two large continents in the east, hence the "islands" appearing between them.

I'm really not sure what you're referring to.

For someone who correctly worked out their plates on a sphere, you're using a very limited definition of "between"
The indigo continent, if that's a better term for it, does in fact have a space between it and the yellow one. That huge ocean. What's happening there?

[MysteryMan23]

@Hydroeccentricity: Indigo? Really? I'd say it's more purple, but eh.

In any case, I would say that on the west coast of the yellow continent and the east coast of the purple continent, you would indeed find subduction zones. I'm not 100% certain what the exact structure of the plate between those two continents is like; it may only exist between those two continents or it could also be between the pink and the red continents. At this point, I haven't made a final decision. This is just a draft, after all.

@Hydro: Anything else you want to say on my current draft of my world's geological history?
