摘要
The paper presents results of palynological studies of the coal-bearing Carboniferous in Central Kazakhstan. A quantitative dynamics of major genera of miospores reflects an overall succession of the Carboniferous miospore assemblages. Visean Serpukhovian assemblages are dominanted by Lophozonotriletes fuscatus, Acanthozonotriletes cristifer, A. inclusus, Punctatisporites glabratus, Crassispora ignorata, C. scrupea, Cyclobaculisporites trichacanthus, Lycospora breviapiculata, L. echinata and Vallatisporites decrescens. Rare Punctatisporites bertschoguriensis , Stenozonotriletes marginellus , Vallatisporites appilicatus , Verrucosisporites serobiculatus , Retieulatisporites caneellatus, Granulatisporites areuatus are recorded, which are not found in assemblages from overlying sediments. Bashkirian-Moseovian assemblages are dominated by Lyeospora subtriquetra, L. pusilla, Vallatisporites ciliaris, Apiculatisporis mollis, Cyelogranisporites testieulatus, Calamospora mierorugosa, Sehopfipollenites principalis, Psilohyrnena psiloptera, Florinites grandis and Granulatisporites piroformis miospores. Cristatisporites latispinus, Angulisporites didymus, Thymospora obseura and Torispora securis are also present, as well as single Apieulatisporis eurvispinus, Raistriekia inordinata, Marsupipollenites retroflexus, Entylissa eaperata, Potonieisporites grandis and Cordaitina sp. A similar succession of miospore assemblages is recorded in the Carboniferous deposits of Europe and North America, which allows carrying out correlations, despite an endemic characters of many species of Paleozoic miospores from the coal-bearing Carboniferous of the Kazakhstan Province in the Euramerian Paleofloristic Region.
The paper presents results of palynological studies of the coal-bearing Carboniferous in Central Ka-zakhstan.A quantitative dynamics of major genera of miospores reflects an overall succession of the Carbonifer-ous miospore assemblages.Viséan Serpukhovian assemblages are dominanted by Lophozonotriletes fuscatus,Ac-anthozonotriletes cristifer,A.inclusus,Punctatisporites glabratus,Crassispora ignorata,C.scrupea,Cyclobacu-lisporites trichacanthus,Lycospora breviapiculata,L.echinata and Vallatisporites decrescens.Rare Punctatis-porites bertschoguriensis,Stenozonotriletes marginellus,Vallatisporites appilicatus,Verrucosisporites scrobiculatus,Reticulatisporites cancellatus,Granulatisporites arcuatus are recorded,which are not found in assemblages from overlying sediments.Bashkirian--Moscovian assemblages are dominated by Lycospora subtriquetra,L.pusilla,Vallatisporites ciliaris,Apiculatisporis mollis,Cyclogranisporites testiculatus,Calamospora microrugosa,Schopfi-pollenites principalis,Psilohymena psiloptera,Florinites grandis and Granulatisporites piroformis miospores.Cris-tatisporites latispinus,Angulisporites didymus,Thymospora obscura and Torispora securis are also present,as well as single Apiculatisporis curvispinus,Raistrickia inordinata,Marsupipollenites retroflexus,Entylissa caperata,Potonieisporites grandis and Cordaitina sp.A similar succession of miospore assemblages is recorded in the Carboniferous deposits of Europe and North America,which allows carrying out correlations,despite an endemic characters of many species of Paleozoic miospores from the coal-bearing Carboniferous of the Kazakh-stan Province in the Euramerian Paleofloristic Region.
