Ore deposit 460 is a large uranium-molybdenum deposit located at the the superimposition of multi-group fractures and volcanic apparatus. Uranium-molybdenum ore bodies occur in the sub-volcanic rock within the volcanic feeder and in the crypto-exploded breccia.  S isotopes indicate that the ore materials are derived from the magmatic hydrothermal fluid and dominated by the crustal materials. The ore fluid is mainly meteoric water heated at depth. Genetically, the ore deposit is a hydrothermal deposit related to sub-volcanic rock.
