Information Extraction And Metallogenic Prediction Of Molybdenum And Copper Deposits In Huoluotai ? District,Mohe County,Heilongjiang Province

Molybdenum anomaly in the mining area has a large area of inner belt,many high-value points,and is a planar anomaly,which is well matched with copper anomaly.The front element arsenic is distributed around the molybdenum anomaly,and most of the physical visit polarizability anomaly is distributed inside the molybdenum anomaly,showing a circular distribution.The alteration and mineralization characteristics of zk32-1core constructed in 2018 are very similar to those of the standard porphyry type.In conclusion,the mining area has In order to find out the prospect of porphyry copper molybdenum deposits of industrial significance,it is necessary to carry out further drilling engineering to further understand the mineralization and alteration in this area and to search for ore-bearing porphyry bodies.This area is located in?-47-1-1 Fukeshan-huoluotai Au Cu Mo ore concentration area.Area IV is characterized by surface alteration and mineralization,from inside to outside and from deep to shallow:Potash?microclinization?zone,sericite?or mica quartz?zone and qingpan lithification zone;industrial mineralization is mainly developed in the middle and lower part of Sericite lithification zone and potash zone.It is found that the phase states of fluid inclusions are three-phase inclusions containing carbon dioxide,sub mineral inclusions and gas-liquid two-phase inclusions.The fluid homogenization temperature is 146⁴41?,the salinity is 6.13%⁴5.88%,and the density is 0.65¹.139 g/cm³.The fluid in Zone IV is high salinity and CO₂ rich.The main factors of mineral precipitation are fluid boiling and temperature reduction.The anomalies of medium high intensity and low resistance IP and Mo,Cu,Pb,Zn are ore-induced anomalies.The concentration areas of Mo and Cu anomalies basically reflect the deep mineralization and enrichment center.The porphyry alteration zoning in Area IV is obvious,the shallow part is greisenization,the deep part is potassic,the hydrothermal activity and mineralization are strong,and the prospecting potential is large.Therefore,the deep prospecting should be carried out around the northern Mo?Cu?concentration center and the middle high polarization and low resistance area.The deep alteration features of the mining area are representative in line 32.Take zk32-1 as an example:0-70m is the main vein silicification and disseminated pyritization.There are good molybdenite?16m industrial grade ore body,average grade 0.07%?developed in this alteration zone.In the 270⁴30m section,there are mainly veinlet silicification and disseminated pyritization,and the quartz vein frequency is 6¹5/m,among which molybdenite is filled According to the analysis results of basic samples,they are all above mineralization,and there is a 27m low-grade ore body with an average grade of 0.04%.According to the existing results,several ore bearing porphyry bodies formed in the same period are found in the huoluotai ore concentration area,which has a good guiding significance for the future exploration of copper molybdenum porphyry type ore?point?deposits in the north section of Daxinganling.The study area has obvious alteration characteristics of porphyry copper molybdenum deposits.The next step in this area is to trace and control the discovered ore bodies,which has the potential to find medium-sized copper molybdenum deposits.
