Abstract��
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�� Viséan 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 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��Schopfipollenites principalis��Psilohymena psiloptera��Florinites grandis and Granulatisporites piroformis miospores�� Cristatisporites 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 Kazakhstan Province in the Euramerian Paleofloristic Region�� |
