adj.[地]微晶灰?guī)r含量高的

The metamorphic micritic limestone intercalated with metamorphic muddy siltstone in the lower part is assigne... 上部以變質(zhì)細(xì)粒砂巖為主夾變質(zhì)粉晶灰?guī)r,厘定為納興組。

Blackish micritic limestones frequently accreted with grayish mudstones.They were the results of deep to semi-deep lacustrine environments. 深灰色泥晶灰?guī)r常與灰黑色泥巖伴生，是深湖-半深湖環(huán)境產(chǎn)物。

Middle-Upper Cambrian dolomites in Shimen,Hunan Province,are mainly composed of anhedral micritic dolomite,euhedral and subhedral granular dolomites,grain dolomite. 湖南石門中上寒武統(tǒng)白云巖極其發(fā)育,類型多樣,不同類型的白云巖其成因機理和白云石化模式各不相同。

Micritic dolostone occurs widely in the Middle and Upper Cambrian and is yellowish brown and brickcolored red, in which parallel laminae, bird's-eyes and mud-cracks are developed. 準(zhǔn)同生白云巖廣泛出現(xiàn)于中上寒武統(tǒng)，巖石呈土黃色、磚紅色，具紋層、烏眼、乾裂構(gòu)造。

Triassic ammonites,fossil plants and radiolaria occurred in normal sedimentary micritic limestone,detrital rock and silica rock and represented the sediment age of the Bayankelashan Group. 其中三疊紀(jì)的菊石、古植物、放射蟲等標(biāo)準(zhǔn)化石分子產(chǎn)于正常沉積的泥晶灰?guī)r、碎屑巖、硅質(zhì)巖等巖層中,代表巴顏喀拉山群的沉積時代,且在縱向與橫向上控制程度高。
