Geological Characteristics And Genesis Of Guirenfeng Rubidium Deposit,Guangdong

The Guangdong Guirenfengyu deposit is located in the southern section of the Wuyi metallogenic belt in Guangdong Province.It is a newly discovered and prospected antimony deposit in recent years.The census of Guirenfeng Mining Area is a small-scale molybdenum deposit.New rare metal minerals have been discovered through comprehensive exploration.It is estimated that Rb2 O resources are large and the grade is high.The strontium ore body is found in the altered rock in the contact zone of the rock,and the genesis belong to the magmatic high-temperature gas-liquid deposit.The strontium element is mainly present in the metamorphic rock mica mineral,which can be confirmed by the optional ore test.Effective recycling.At present,the types of antimony ore industries mainly include alkaline feldspar granite type,pegmatite type and salt lake brine type.Other types of antimony deposits are small in scale or have not been developed and utilized on a large scale.The discovery of the Guirenfeng deposit provides a new idea for the prospecting of antimony deposits in China.In-depth study of the Guifeng peak deposit,summarizing the law of mineralization and enrichment,and exploring the genetic mechanism,has important theoretical and practical significance for guiding the comprehensive prospecting of rare metals and finding the same type of antimony deposit.Based on the previous research work,this paper summarizes the mineralization enrichment rules and discusses the genesis of deposits by conducting research on mineral geology,petrography,rock ore geochemistry and mineral geochemistry of the Guifengfeng polymetallic deposit.Have the following understanding of the Fengfeng polymetallic deposit:1.Molybdenum mineralization and strontium mineralization are in the same symbiotic relationship.From the plane and depth direction,the mineralization range of molybdenum and niobium is basically the same,and the molybdenum ore body almost overlaps with the niobium ore body,but the niobium mineralization range is much larger than the molybdenum mineralization range.The rock mass contact zone structure controls the morphology and occurrence of the ore body.Different lithologies,metamorphism levels,and strontium content are different.Generally speaking,strontium is relatively concentrated in sandy rocks and rocks with high metamorphism.2.The study of geochemical characteristics of rocks shows that the granite peaks of the noble peak are rich in silicon,alkali,weak aluminum and high-differentiation.The trace elements show the relative enrichment of large-ionic lithophile elements,especially the Rb and K elements are rich.Set;Ba,Sr,P,Ti loss is obvious.Rare earth elements have the characteristics of obvious light rare earth enrichment and heavy rare earth loss.Based on the geochemical characteristics of the rocks and the regional tectonic setting,it is believed that the Guirenfeng granite is a crust-generated granite formed in the extended tectonic setting,and the genetic type of the granite is initially classified into S-type.3.The noble peak polymetallic deposit is closely related to the late Jurassic concealed granite body and belongs to the magmatic high temperature hydrothermal deposit.
