Abstract

Abstract

Analcime phonolite is a rare alkaline volcanic rock.Using the electron microprobe, X-ray powder diffraction, scanning electron microscope, and Raman spectroscopy, this paper studies characteristics of rock-forming minerals, coexisting relations and crystallization sequences of the analcime phonolite from the Damxung area, Qinghai-Tibet plateau.Phenocrysts are euhedral analcime and feldspar, while the groundmass is composed of K-feldspar, salite, titanomagnetite, and limonite.Analcime is primary and crystallizes in the late magmatic stage.Phenocrystal feldspars have secondary rims of K-feldspar, and their cores are plagioclases.Crystallization sequences are the plagioclase core of feldspar phenocrysts, analcime and K-feldspar in the rim of feldspar phenocrysts, K-feldspar in the groundmass, salite, titanomagnetite and limonite.The balance between analcime and melt places constraints on the P/T regime (5-13) ×108 Pa and 600-640 ℃ respectively, implying depths of origin in the deep crust.
