Crust Age #56

Open TheNewParad1gm opened 4 years ago

TheNewParad1gm commented 4 years ago

I was really hoping to use crust age to allocate shield regions on my map, unfortunately only ocean crust seems to have an age, with continental crust being a uniform shade.

Is there a reason for this... and could it be changed?

I was going to do this so that I could start adding in a few other mountain range areas, as I find that all too often there are very few ranges formed. I often end up with 'patches' of higher ground rather than chains of mountains, and can't seem to produce something which looks overly convincing (compared to our earth norm). Even when left for 4.3Gy I still ended up with things like this mostly. I'd have thought at this age there'd be a number of mountain chains on continents that aren't at plate boundaries, from historic plate collisions. Hegenos4-34_Topo

It actually does have an age, but it doesn't show up in the display since it's typically an order of magnitude older than ocean crust, and I figured people wanted to focus on the ocean age since that affects plate motion.

That's definitely a good reason though, I hadn't considered using it to find the shields. I'm trying to think about what we can do to satisfy both use cases. A general solution might be to add a slider for the user to specify color scale ranges, but it's not as simple a fix. Would it make sense to you if we toggled between ocean crust age vs. continental+ocean crust age based on whether oceans are visible?

A toggle would be simple and easy to understand and really useful. It doesn't really matter if it's all together. I'm swapping out various other views as underlays to make my own maps anyway.
