Ores
Ores are primary crafting materials necessary for game progress. They generally must be crafted into bars at a Furnace, after which they can craft several essential tools, weapons, armor, and other items. Some items require raw ores themselves, most commonly bricks and potions. Raw ores can also be used as plain blocks for construction. Ores are …

What are the tiers of the ores in Terraria?
As of 1.2, every world gets either one or the other generated: Standard Ores can be found almost everywhere underground: Copper or Tin. Iron or Lead. Silver or Tungsten. Gold or Platinum. Demonite or Crimtane. Demonite and Crimtane are rarely generated, so that's why The Eater of Worlds and the The Brain of Ctulhu drops them in …
Regional metallogeny of Tungsten-tin-polymetallic deposits …
With the accumulation of ore-forming geological data related to tungsten-tin deposits in Nanling region (Table 2), although controversial, it has been concluded that mineralization related to magmatic activity in Nanling region is of long-term nature and inheritance (Chen et al., 1989, Wang et al., 2018). For example, the famous …
Tungsten Ore
Tungsten Ore is an early game ore which spawns in the Underground and Cavern layers as well as on Floating Islands. Its primary use is to make Tungsten Bars, which can be used to make the Tungsten tier of equipment. The equivalent of Tungsten Ore is Silver Ore, which will sometimes replace Tungsten in a world. Tungsten Ore has a small …
