Ore Generation

When an ore is generated, if there was a type of stone (Stone, Red/Black Granite, Basalt, Marble, Netherrack, or End Stone) in that location, the ore takes on that stone's base type (note that ores can not generate in other blocks, such as dirt). So if an Iron Ore generates on Netherrack, the ore has a stone type of Netherrack, but is still Iron.
