In the last 5 days, I've skimmed through tens of articles, books and mineralogy websites to get a better grip on Ore Genesis.

Soil 60% Done
Soil layers stay much the same, though non-pottery clay has been renamed to "mud", to lessen confusion.
Some ore such as Lignite and Bog Iron can be found as small clusters in most soils and as veins in peat, as well as Mangan Nodules in Ocean Sediments.
Clay will appear as large Clusters in soil, rather than whole layers, and most embarks will probably have clay as a result. Further more, Laterite/Bauxite Clusters in soil may be a way to add certain oxide ore in soil. Gypsum Clusters in sand, is another way to find carbonate ore in soil layers.

Layer Stone
The aim here is to provide a few new geodomes for minerals to appear in, that are each part of a mineralogical family.
If to rocks are essentially very similar in composition and what it contains, they should generally be regarded as the same, ex. Norite & Gabbro or Thoelite and Basalt.
Large Clusters in Layer stone
To add reaction environments such as skarns, weathering, gossam, intrusions etc. the following are hypothetical inclusions in layer stone.
not all of the minerals shown will make the final cut, but I've included them to create a scope of possible outcomes.

Minerals and ore:
I've Dug about the Mineral books to find nearly all commersial ores that are used today, and added a small note to each one where to find them.
Most common environments are still skarns and sulfide enrichment zones. It will be a challenge to incorporate it all into a working system in DF, and some of the minerals will probably not make the cut, to reduce bloat. Most of all, the list is a guide to which environment I should focus on, i.e. Carbonate skarns/gauge, laterite, hydrothermal deposits, Porphyry deposits, ultra mafic enrichment environments, evaporites and so on.

Metals
I removed most of the Alloys to make room for more metals. Some metals are beyond Medieval technology and some hvae fantasy names, but are based on real alloys/superalloys. Only Vanadine and Thorium have unrealistic fantasy values, with real vanadium being super hard but brittle, and thorium being a very terrible radioactive metal.
The alloys build on the steel industry mostly, reducing the ammount of steps for normal steel, but adds a few steps for higher grade steel, with thematic rather than realistic names, i.e. Rune Steel and Mithril.
