摘要
通过对贵州省凯里黄飘地区红花园组进行地层剖面实测和岩矿样品镜下观察鉴定与分析,共识别出6种碳酸盐岩微相,即:MF-1包壳生物碎屑亮晶灰岩; MF-2生物碎屑泥晶灰岩; MF-3鲕粒亮晶灰岩; MF-4具窗格孔泥晶灰岩; MF-5叠层灰岩; MF-6集合颗粒亮晶灰岩。通过与Flügel(2010)的镶边碳酸盐岩台地标准微相类型进行对比,认为黄飘地区红花园组碳酸盐岩形成于台地边缘滩与滩后(局限台地与开阔台地)沉积相带。综合分析表明黄飘地区下奥陶统红花园组经历了3期相对连续完整的次级海进-海退旋回。
Based on section measurement, sample collection, indoor section, microscopic observation and analysis in Honghuayuan formation in Huangpin area of Guizhou, 6 different kinds of carbonate micro-facies are reeognized：MF-1 Coated bioelastie grainstone, MF-2 Bioelastie waekestone, MF-3 Ooid grainstone, MF -4 Fenestral paekstone, MF-5 Laminated stromatolite limestone, MF-6 Aggregate-grain grainstone. By compare with standard mierophase type of marginal carbonate platform pattern facial belt proposed by Flugel （2010） , it＇ s suggested that carbonate rock in Honghuayuan formation was formed in sedimentary facial belt of plafform-margin shoals and behind the shoals （restricted platform and open platform）. The generated analysis shows it experienced 3 periods of transgression-regression sedimentary cycle in Honghuayuan formation （ lower Ordovieian） in Huangpiao area.
