山东昌乐锆石的谱学特征及变生程度
Spectroscopic Characteristics and Metamict Degree of Zircon from Changle of Shandong
摘要
Abstract
The spectroacopic characteristics and metamict degree of zircons from Changle in Shandong are discussed by using LA - Raman spectra, IR absorption spectra and gemmological characteristics. LA - Raman spectra show that the zircons are crystalloid zircons and weak-metamict zircons, because H/W ratios(1 007 cm-1) are higher than 600 (625 -5 412 ) with one exception(441). IR absorption spectra show that crystal-Unity of zircons are similar, because all the H/M ratios (610 cm-1) are 20 - 23, 20 - 22 after heat treatment in oxidizing condition(600 ℃) and 28 -30 in reducing condition(600 ℃). It can be concluded that the zircons are crystalloid zircons; the gemmological characteristics are also similar to the crystalloid zircon. All the experiments above hold that the samples are typically the high-type zircon and metamict coefficient of zircons becomes bigger notably and crystallinity is improved after heat-treatment in reducing atmosphere.关键词
