板状绿柱石产于花岗岩云英岩化边部或晶洞壁的白云母-钠长石-绿柱石-水晶的矿物组合中,钠长石呈自形晶,绿柱石的洁净度与透明度相对较差。晶体测量表明,晶体的单形晶面发育依次为c{0001}→s{11 2-1}→p{10 1-1}→m{10 1-0}→v{21 3-1}、n{45 9-4}、a{11 2-0}。微分干涉显微镜(DIC)及扫描电镜(SEM)研究表明:各单形晶面上生长纹(微形貌)反映面网结构的对称性,c{0001}单形晶面上的六边形溶蚀坑(50～170μm)是由平行晶体C轴的各单形晶面生长层从晶体中心向外叠堆组成,层生长机理制约晶体生长全过程,平行双面(c)的生长层较薄(5～8μm)且较稳定,六方双锥(s)生长层较厚且圆滑,六方柱(m)生长层由晶体中心往外其厚度由厚逐渐变薄(12～20μm),台间隔由窄变宽。晶体溶蚀是从面网密度最大的c{0001}开始,溶蚀面积依平行双面(c)、六方双锥(s)单形晶面由大变小,六方柱(a)、复六方双锥(v、n)单形晶面因面网密度小而未受到溶蚀。据矿物共生组合、流体包裹体均一法测量与拉曼光谱(LRS)分析表明板状绿柱石是在中–高温(303℃)、过饱和度较大、成矿介质的钠长石化发育且热动力环境相对稳定的条件下形成,气液包裹体主要由H2O、CO2及微量CH4、N2组成,CO2及微量CH4、N2可能与碳酸盐围岩有关。
Platy beryl is produced in the mineral assemblage of muscovite-albite-beryl-quartz in the granitic cloud-weathered margins or cave walls, where albite appears to be a self-shaped crystal, with the purity and transparency of the beryl Poor. The crystal measurements show that the single crystal growth of the crystal is c {0001} → s {11 2-1} → p {10 1-1} → m {10 1-0} → v {21 3-1}, n {45 9-4}, a {11 2-0}. Differential scanning microscopy (DIC) and scanning electron microscopy (SEM) studies show that the growth pattern (micro-morphology) on each single crystal plane reflects the symmetry of the net structure, hexagonal corrosion on c {0001} The pits (50-170 μm) are composed of single-crystal plane growth layers stacked parallel to the C-axis of the parallel crystal and stacked outward from the center of the crystal. The layer growth mechanism restricts the entire process of crystal growth and the growth layers with parallel double-sided (c) 5 ~ 8μm) and more stable, the hexagonal bipyramid (s) growth layer thicker and sleek, hexagonal (m) growth layer from the center of the crystal thickness gradually thinning from thick (12 ~ 20μm) width. The crystal dissolution starts from c {0001}, which has the highest density of surface network. The dissolution area is parallel to both sides (c). The single crystal plane of hexagonal double cone (s) (v, n) single-faceted crystal face due to the density of small surface without being corroded. According to the symbiosis of mineral assemblages, homogeneous analysis and Raman spectroscopy (LRS) analysis of fluid inclusions show that plate-shaped beeshort is at mid-high temperature (303 ° C) with large supersaturation and the albite development of ore-forming medium is hot Under the relatively stable dynamic environment, gas-liquid inclusions consist mainly of H2O, CO2 and trace amounts of CH4 and N2, while CO2 and trace amounts of CH4 and N2 may be related to carbonate rocks.
