Should nuggets be labelled as such in the list? Before they are mined they are referred to as 'Native <metalname>', and are only labelled as nuggets once mined. Perhaps the table should be changed to indicate this. --TangoThree 09:14, 20 January 2008 (EST)

Before they are mined, they can't be smelted. It doesn't really matter which approach is used, as long as it is consistent; this article consistently refers to the post-mining state. VengefulDonut 14:13, 20 January 2008 (EST)

Should we take the Chromite out of the 'Found In' section for Platinum? Chromite is found in Olivine, and Platinum is already found in Olivine.--CrushU 21:58, 14 March 2008 (EDT)

Separate query - anyone know why Toady One requires native gold/silver to be smelted? You don't have to smelt rock to get the gold or silver out, it is gold or silver and you can either melt it for casting or work with it directly. (Historically most gold or silver mined has been melted down so it could be cast into bars for ease of transportation, but its still perfectly plausible to work with it in its raw state - rarely have the metalsmiths/jewelers been so close to the mining operations as in this game). I believe this is also true of native copper (hence why copper weapons/tools vastly predate iron equivalents). Smelting is the process of extracting metal from rock, not just melting it down. --Squirrelloid 16:06, 21 April 2008 (EDT)

Gold Nuggets

So, I'm currently evaluating some gem occurrence data, but noticed that there is no native gold veins that are wholely interior to gabbro (with quite a few gold veins discovered thus far). They may occur at the border of gabbro and other layers, and thus possibly extend into the gabbro, but nothing that could be said 'yep, that was generated in gabbro'. This leads me to believe gold does not occur in gabbro, and gold present in gabbro is only incidental due to a vein running over into it from another stone layer.
(For reference, I've dug 1x140 square tunnels on 55 z-levels such that they are all directly above each other, for a total of 7700 tiles dug out and ~15500 tiles revealed beyond that. I've then mined out all gem clusters i've found, and am working on mining out all veins i've found. The tunnels cross a biome boundary, with transitions of andesite/basalt, diorite/marble, and diorite/gabbro. Gabbro is by far the most common rock tunneled through, followed by diorite, as the diorite/gabbro transition layers are the bulk of the layers)

Any problem?--Dorten 04:28, 29 April 2008 (EDT)

Gold occurs in all igneous. Gabbro is igneous. Gold does not occur in gabbro: a contradiction.

Based on gem occurrence patterns I hypothesize that each main layer (such as gabbro) is limited by the code to only a certain number of inclusions (such as gold), and after this inclusion list is full nothing else is created. For instance, maps will have a lot of one specific type of agate, rather than a little of each; or rock crystal is nowhere to be found in ten maps, and then appears in 15 small clusters in exactly one layer in one map. Any thoughts? Anydwarf 23:11, 29 April 2008 (EDT)

I'm starting to see correlation in gems within rock masses, even across z-levels. There may be something to this. It would also explain why I have a boatload of gold veins, but none in Gabbro. OTOH, I'm starting to think there's more to the mineral/gem generation that just what rock type the layer is - I've been getting some gem types repeatedly associated with areas where the rock layer is 'broken', ie, rock layer type boundaries (say Diorite meeting Gabbro) or next to an ore vein, whereas I'm finding different gems totally internal to rock layer types. This actually makes sense geologically, but I want more data before I say anything definite. --Squirrelloid 23:34, 29 April 2008 (EDT)

I have found the start of a vein of gold in gabbro, so I think that he was just getting some odd, extremely specific thing. I don't know. Destor 14:47, 26 September 2008 (EDT)

You'd have to find a gold vein completely inside a gabbor layer to rule out the vein having just finished running into a different stone layer. I have malachite veins in my current game that terminate in andesite, mudstone, and even soil layers because they kept running past a stone boundary.

Similar to my above query - I haven't seen a single gold vein in granite this game (and wasn't paying sufficient attention in previous games to notice). I have found plenty of Bismuthsite, Silver, and Casserite in granite though.

It still strikes me as highly plausible that the ore/gem generation algorithm is more complex than just 'is it the right class of rock?'.

Native Aluminum

According to the soil article Aluminum occurs in soil as well, but this table and the Native Aluminum article make no mention of it occuring in soil. Can someone verify if it occurs in soil? --Xonara 03:07, 16 January 2009 (EST)
