One thing I have noticed with lava and water reactions is that it only produces obsidian.  Now that is nice in terms of rock type for building, but obsidian is only made from felsic lava.  Felsic being iron poor, and obsidian is produced from cooling lava.  What I propose is that lava cooling produces rocks other then obsidian like granite (if underground) or rhyolite (same molten material, different cooling rate) if felsic or basalt if mafic in nature and everything in between.

Yeah, all igneous extrusive rocks should be able to be produced by magma.

However, igneous intrusive rocks, such as granite, form much too slowly to form in the game.

Forming either pahoe'hoe or a'a would be a nice touch. You do NOT want to trip over a'a.

I'd imagine that you'd yell out with cries of "a'a" if you did.

Maybe so, but I was just tossing the idea out there.

"Mama cooling"?  Heh

Anyhow, I like this suggestion.  I don't think the game tracks whether our magma is felsic or mafic, though.

I don't think that would be to hard though, just have two types of magma, if they mix then the third kind is made.

You could treat it like stagnant and salt water, but the problem is the three magmas behave differently.

[Starver]

If you've got different types of magma, then should some now advance really slowly (compared with current in-game magma-flows) and some actually be very rapid indeed!

It would certainly make my boring old magma-tapping method a bit more exciting (or need a bit more local research) if there was a possibility that my carefully-honed plans that in part assume a slow flow-rate turned out to be in error on this point...

Also, the self-same method tends to end up with an isolated channel of magma.  I imagine that as it cools (initially from the point the heat-pipes from the forges above are inserted, in order to obtain the working temperatures needed), my magmaduct that is dislocated from the main core-fed magma chamber would eventually become solid (albeit still hot-to-the-touch) rock, of whatever sub-variety.

Silica content is key: Magma could have the consistency of olive oil to molasses left in the fridge overnight. Generally, thin flows make pahoe'hoe and thick ones a'a.

And silica content affects what the magma/lava cools into. High silica, rhyolite or obsidian, low silica, basalt.

Oh goddammit it, now you've done it... another day wasted on Wikipedia.
