内蒙古维拉斯托锡多金属矿床含矿斑岩体钾长石斑晶的有序度及成因探讨
THE ORDER DEGREE AND ORIGIN OF K-FELDSPAR PHENOCRYSTS IN THE MINERALIZED PORPHYRY OF THE WEILASITUO POLYMETALLIC DEPOSIT IN INNER MONGOLIA
摘要
Abstract
The study of order degree and structural temperature of K-feldspar can provide significant information about the forming physicochemical conditions of deposit.Infrared spectroscopy is used to test the K-feldspar phenocrysts from the mineralized porphyry in the Weilasituo polymetallic deposit.The result shows that the order degrees range from 0.85to 0.95,with triclinities of 0.7-0.9.The structural temperatures are 547.17-578.36 ℃,suggesting that the K-feldspar phenocrysts are microcline.It is confirmed that the K-feldspar is a product of hydrothermal alteration.关键词
