40d Talk:Magma

Are you certain that steel is a requirement for metals in contact with magma? This info conflicts with the Magma smelter article, which state that using Fire-safe materials is enough. Don't have a fort with magma yet, but could someone check which one is correct?Thexor 19:23, 31 October 2007 (EDT)

If i disable temperature can my dwarfs swim through the magma unharmed? Will it still cause water to steam? Diabl0658 22:28, 31 October 2007 (EDT)

Does the type of rock around the mountainous areas hint at magma? If you check out this article and this site list a bunch of common volcanic rocks: Granite, Rhyolite, Diorite, Andesite, Gabbro, Basalt, Peridotite and Komatite. Perhaps some clues as to where to find magma?

It may be possible to find magma vents by searching for extrusive igneous rocks (such as basalt, felsite, rhyolite and andesite), but continental shelves and deep earth are just naturally made of intrusive igneous rock (such as granite, diorite and gabbro). It's generally indicative of rock that has been pushed up to the surface (or erosion has withered the rock down), and not a volcano.

So areas with surface igneous rocks such as basalt, felsite, rhyolite and andesite have a high chance of finding a source of magma below the surface? I'd like to know if it's entirely random or if there is some order or pattern to it. Schm0 08:38, 5 November 2007 (EST)

On a completely different topic: I keep setting up on magma vents but not actually having a magma chamber visible. I assumed one problem was the lack of a border on my plot (so somehow the volcano was actually outside my plot), but even after making it bigger there was still no magma (...but it did have a fancy cave)...This has happened the last 4 times I've tried to start on a volcano, and the world regenerating takes quite a while for ~10 named volcanoes, and then all of the livable ones don't actually have magma.--UltimaGecko 16:50, 3 November 2007 (EDT)

Tempurature

Does magma increase the temperature of things around it? Can it be used to melt ice? --Ikkonoishi 20:26, 3 November 2007 (EDT)
