Catpaw, check out the suggestions forum. It sounds like you have a lot to contribute.

Well, rock hardness is quite do-able, although I must disagree with the suggestion of moh's scale. Thats more for scratch resistance of minerals. Ie: diamonds are very 'hard', but shatter on impact.

What we want is really just called rock strength (ie. unconfined compressive strength). Its an engeneering measure describing how strong the rock is, for supporting or for digging out. You can actually estimate it with a hammer. Weak rocks are usually sedimentary, such as salt and gypsum. Hard rocks are usually fine grained volcanic such as basalt. The scale ranges from 0-200 (ish). Some info: http://www.google.ca/url?sa=t&source=web&ct=res&cd=3&url=http%3A%2F%2Fwww.itc.nl%2Flibrary%2FPapers%2Farti_conf_pr%2Fhack_huisman.pdf&ei=wljBSIyxApqSgQLlia3VBg&usg=AFQjCNEk4silMs40TbPpSG-CV6rKHZB7Aw&sig2=64e3en4wvq5MpMgxyhH16g


I think I've got a set of example numbers in a textbook..


As to rock groupings, look to bowens reaction series (for igneous rocks). http://en.wikipedia.org/wiki/Bowen%27s_reaction_series . Minerals that are more than one spot away (vertically) are unlikely to co-exist, because at the time of formation, they would be chemically unstable and transform into the material in-between. So, no quartz near olivine.
You can then look at rocks (multi-mineral combinations). I think Toady has done this part, as we see the difference between extrusive and intrusive volcanics. It might be worth grouping the acidic and basic volcanics seperatly. Obsidian is very acidic (it is quartz-y) so will not occur in basic volcanic rocks.

If you look at igeous rock at wikipedia, down at the minerological classification of volcanics, you see a table showing what volcanic rocks should go together. (felsic == acidic == granite, mafic == basic == basalt).

Another thing. In magma chambers (where you get lots of intrusive igneous rock), you get vertical separation (layering) based on the temperature of crystalization. As a magma body cools, the high temp minerals crystalize first and sink to the bottom.

If this info is handy, I have more

Why not move this to the wiki? The wiki interface is much better for building an updated list.

My mayor has a new demand. "item in Throne Room/Office"

Is this a bug, or am i supposed to guess what item he wants?

I tried assuming he wanted just any item, & placed a few new pieces of furniture in his office, but it didnt seem to help.

Happened to me too. Time to lock your hammerer up.

(I have no idea if traps work after a fortress is abandoned, either way, it should be rather interesting)

AFAIK, they work, but you can't avoid them.

Yeah, you need less than 7/7 water, as when the water goes from, say 4/7 to 5/7 there is a chance it will move something, but going to 7/7 just instantly submerges the object.

Ah, thats useful to know. My original design had the water drop directly onto the object from above from a hatch, but since thats just dropping a 7/7 depth square of water onto the thing instantly I guess that wouldn't work.

drop the water 1 square to the side, so that it spreads out first?

Lol, I just now noticed that your avatar is an owl or a pair of owls Neoskel. I have been thinking of the breast feathers as teeth in a mouth, and this was a relevation.

Oh. Yeah, owls are much less disturbing. Thanks for sharing your noticing

I'm suprised none likes the "fill the world with ice" idea, no takers at all?

I like the idea. A giant ice cube. Build a floor on a top level that can open/close, pump water over a level, open the skylight, freeze. Repeat on each level.
