Mississippian (early Carboniferous) radiolarian biostratigraphy of northern Thailand (Chiang Dao area)

Well-preserved Carboniferous radiolarian faunas were obtained from ribbon-bedded siliceous sediments (radiolarites) north of Chiang Dao city, Chiang Mai province, northern Thailand. These sediments are rich in identifiable radiolarian faunas, including more than 44 species and sub-species belonging...

Five Early Carboniferous radiolarian assemblage zones are recognised and compared to those of Germany, France and North America. They are, in ascending order: the Albaillella paradoxa gr. assemblage; the Albaillella indensis gr. assemblage: the Albaillella cartalla-Albaillella furcata furcata assemblage which includes the Palaeolithocyclia rota subassemblage; and the A. furcata rockensis-Latentifistula impella gr. assemblage. The age assignment of each assemblage is well-controlled by co-occurring conodonts, which are abundant during this time interval in the area. The Thai radiolarian assemblage zones are rather similar to those of Germany and North America, indicating that the albaillellarian form has a global distribution and can be readily used as a world key indicative fauna.
