石英颗粒 meaning in Chinese
quartz grain
Examples
- The feldspathic sandstones belong to this formation of composite sources metamorphic , sedimentary , and igneous sources , but mainly from metamorphic source due to the high abundance of brown cl colors of quartz
上述情况表明，研究区长石砂岩物源母岩包括变质岩、沉积岩与火成岩，但从发育大量棕色石英颗粒来看，物源以变质岩为主。 - As quartz fraction in loess is separated by the tedious process of etching with fluorosilicic acid for 6 days , 20ml 30 % fluorosilicic acid per gram , not only the feldspars in loess could be removed completely , but also less quartz could be etched away in loess
溶蚀实验表明，用40 hf溶蚀40min对石英的损失太大，不适合黄土中石英的分离。用30氟硅酸（ 20ml冶）溶蚀约6天，分离黄土中的石英颗粒，既可以溶蚀掉长石颗粒，又对石英的损失较小。 - The mineral rock - silica rock mostly composes of three kinds of silica qualities , and the first structure jasper silica rock , the second icrocrystal quartzite , the third the quartz grain clast . cement is carbonate , contain a little amount carbonate loach . silica rock , commonly assume edge angle or hypo - edge angle
区内的含矿岩石?硅质岩主要由三种硅质成分构成，第一种为显脱玻?霏细结构的碧玉质硅质岩，第二种为微晶石英岩，第三种为石英颗粒内碎屑。 - The cathodoluminescence ( cl ) analysis shows the quartz reflects an abundance of brown color , blue - purple , dark blue , dull color , and no cl color for quartz overgrowth , while feldspar shows light blue , yellow - green , yellow - brown , green and brown cl colors . the calcite reflects bright orange - yellow for non - ferroan calcite and dull orange - brown cl colors for ferroan calcite
阴极发光分析证实，砂岩中石英颗粒阴极发光颜色较深，主要位棕色、蓝紫色、深蓝色，石英加大变不发光；长石颗粒阴极发光颜色主要位浅蓝色、黄绿色、绿色、棕黄色等；无铁方解石阴极发光颜色为鲜艳桔黄色，铁方解石阴极发光颜色为暗桔黄色。
