河南栾川县松树台钼钨矿床及其控矿岩体地质地球化学特征
The geological and geochemical characteristics of Molybdenum Deposit and its ore-controlling rocks in Songshutai Luanchuan County Henan Province
摘要
Abstract
The Songshutai hidden Molybdenum‐Tungsten deposit lies in Huangbeiling metallogenic belt of the famous Nannihu molybdenum ore field .The area shows a good prospecting potential according to the widely distribution of Minor intrusions and well‐developed faults .Orebodies occur in the contact zone of marble and granite porphyry of Sanchuan formation ,with molybdenum ore types of marble ,skarn and gran‐ite porphyry .The deposit resource of MO and W can reach medium‐scale with a high grade .The respective‐ly average grades of Mo and associated W are of 0 .12% and 0 .08% .Huangbeiling Porphyritic granite relat‐ed closely to the mineralization ,is a kind of caic‐alkaline rock with high grade of silicon and K .The rock show s some features as follow s :the average contents of SiO2 ,Na2 O + K2 O are respectively of 73 .83% and 8 .97% ,σ=2 .01‐3 .28<3 .3 ;And LREE shows relative enrichment .The elements of Ce and Eu show nega‐tive anomaly with the respectively average value of δEu andδCe of 0 .40 and 0 .56‐0 .78 .The rock is much poorer in Sr and Ba but richer in the large ion lithophile elements .T hese features are similar to those of Nannihu and Shangfang granite .It can conclude that Songshutai molybdenum deposit can be classified as porphyry‐skarn type ,being the same type with Nannihu and Shangfang molybdenum deposit .The ore bodies may extend to the endless depth and with greater prospecting potential .关键词
