The Jiguanshi silver and gold ore deposit was developed inside a rock body The ore body is vertically infilling vein - like and dominated by silver and gold - beating massive pyrite ores with REE = 109. 248 - 4. 18, Eu = 2. 40 - 0. 90. and LREE/ HREE = 12. 81 ~ 8. 94. The REE chondrite normalization model is in a right - dipping form. The melallogenic substance is sourced from the 20 ~ 30km deep ultrabasic magma resulted from the dissolving and separation of the intermediate - acid magma.
