fauna belongs to the Zhujiang sub-form of Huanan form with typical characteristics of the Pacific graptolite fauna.───動物群屬于華南型的珠江亞型,具有典型的太平洋型動物群的特點。
optical anisotropy of zooclast graptolite in some Paleozoic strata of China has been studied using reflectance cross-plot analysis.───應用反射率十字圖解研究了中國部分地區下古生界地層中動物有機碎屑筆石的光學各向異性。
nature of graptolite fauna, the correlation of the graptolite-bearing strata with that in other area and the Cambrian-Ordovician boundary are also discussed.───還對筆石動物群的性質進行了分析,與鄰區和國外相當地層進行了對比,并討論了本區寒武系與奧陶系界線。
These provide base for the correct measurement and valuing of graptolite reflectivity .───從而為筆石反射率的正確測定和取值奠定了基礎。
Ordovician graptolite fauna characteristics and sedimentary environment of Gongcheng, Guangxi, Chin───廣西恭城奧陶紀筆石動物群特征與沉積環境
Silurian High Resolution Graptolite Biostratigraphy and Biotic Recovery in Ziyang, China───中國紫陽志留系高分辨率筆石生物地層與生物復蘇
Discovery of Early Silurian graptolite fossils in the Qimantag Group in the western sector of the East Kunlun───東昆侖西段祁漫塔格群早志留世筆石化石的發現
A global correlation of the graptolitic strata of this interval is preliminarily proposed, and the biogeographic distribution of Early Devonian graptolite species is discussed in the present paper.
The black graptolite shale facies indicate a deep - water, half enclosed and anoxic sedimentary environment.
These provide base for the correct measurement and valuing of graptolite reflectivity.
But the most surprising fact about this is that all these events took place during the deposition of a single graptolite zone.
