Test 5:

Civ has access to iron but no copper. Few variety, adamantine almost non existent and abundant tetra. I thought the magma sea didn't changed much.

Same seed.
Aquifer, flux and 2 biomes. 5000 Scarcity.

A good value of tetra. Maybe 4500 scarcity is better. However, old test 4 site didn't have any metal at all in the new world gen and scarcity setting. Overall, the world seems like have less metal. Civ got copper but no iron.

Hate to inteject again, but are you testing the same embark size and location each time?

Much gold. Test site 4 still have no metals. I'm almost sure that site embarking is just luck,as 10k gold for 4500 scarcity is way too much. Also, no flux layer, shouldn't have gold here. Civ got no copper nor iron.

Hate to inteject again, but are you testing the same embark size and location each time?

No, actually. I'm trying to see some global change, some pattern. But let's get to site 4 and see the results.

Test site 4.a, exactly the same place.

No metals at all. Scarcity 4500, 3 biomes, no flux.
Adamantine variation. It's the same place, I took an screenshot. Hmmm.

4.b, exactly the same place. 3500 scarcity.

Embark mentioned only deep metals. 510 galena. 3500 metal scarcity, same as the original test site 4 test. Seed is the same, just history, creature and name seed are not fixed.

[Girlinhat]

I'm getting lost in my search for circles, and frustrated by it.  Seems that no one has an old-school method to plot points anymore, they all demand that you use an actual graphics display to draw the circle... anyways, I kinda lost track on what you were doing   But, if you want real Science!!, you should embark with the same seed and the same location, with the only difference being scarcity.  Perhaps do this for a few variations of scarcity and then throw it up all at once as a table?

Saw your topic about circles in grid some time ago. Good luck with your search! Can't help you, sorry, I'm not good in drawing, cutting or doing anything that needs a geometrical shape. =/ Only 1x1m squares used in archaeological excavations.

I started doing this a while ago, still, the site has some variation. Strange. I will take a few screenshots and regen the same world with the same scarcity, to see if the metal distribution changes.

Conclusions:
Inconclusive.
Metal scarcity affects a little the internal shape of the site, and the frequency of non-economic ores, not just metal ores.
In example: 4.c got 12k Tetra and 460 galena and 1.2k microcline(non economic stone), and in 4.e got 6k galena and 35k microcline, yet not one unit of tetra. 4.d didn't have metals listed, only 1k of cobaltite.

Same seed and site was used in all tests, and it will return the same valor if you put the scarcity you used before. Yet, the metals don't assume a mathematical behavior, such as an Arithmetic progression, Geometric progression or in a exponential function, etc such as one could expect. It seems it adopt a random pre generated behavior. So, with 2000 metal scarcity you can get no metal, in 2500 you can get 6k tetra, in 3000k you could get 4k galena and no tetra.

[parlor_tricks]

Bravo - you've made a science experiment riveting.

Particularly the way the !!Science!! becomes more Science with tighter constraints.

Incidentally - from 4.a to 4.e it seems that metals are not genned at all, and only at the lower levels do we see metals start to appear. - Is it possible that the geographic layout of the location (sedimentary region/metamorphic region) is influencing the type of minerals/metals that can be generated? (I assume this is the case - more volcanic regions should have more metals imho)
What region are we looking at it?

Maybe the geographical is influencing, yes. I embarked with Gold + flux, and embarked with gold + no flux. Can't say this obeys the metamorphic, sedimentary, etc layers. In theory, a volcano should have and abundance in basalt, maybe obsidian if it was near a lake or depending the climate zone it is located, with a a good amount of chert and chert-arenite.
Iron ores seems the most rare to get. Also, the less is the Mineral Occurrence Setting, the more non metal stone appears in certain areas. Besides that, I think this whole thing is random.

Region:
volcanic activity in the word is default. The non default gen are cavern layers (1) and cavern openness/denseness

It seems to be remarkably random, but a general "rule of thumb".  This was far too small of a pool to make and conclusive claims, but we ALL know how random the world generator can be.  If you were to repeat the test several more times with several different seeds, and started to graph the results, you'd probably get a vague curve.  After all, we've all had a .18 map with nothing on it, and .19 maps with so much ore you wonder how the whole world hasn't collapsed on itself.

It's never prospected whole layers, it only prospects cluster types.

It has hidden functionality to prospect layer stones:

dfprospector.exe -ab

Enter that on the command line, or make a .bat file in the same directory with that as the only line.

It would be hilarious if there was a new bug and we have somehow been missing layers of hematite in the previous tests.

Would the results be different in more mountanious/volcanic regions? From what I remember hematite should be in igneous layers and sedimentary.
