ODZWIERCIEDLENIE STRESU ŚRODOWISKOWEGO W PALINOFLORZE PÓŹNEGO PERMU W POLSCE

Abstract

IMPACT OF THE ENVIRONMENTAL STRESS ON THE LATE PERMIAN PALYNOFLORA FROM POLANDAbstract. The abnormal pollen grains of the Lueckisporites virkkiae Potonie et Klaus species were recorded in the Late Permian microfloristic assemblages from Poland. These morphologically mutated miospores were already described by Visscher in the Permian succession of Western Europe and became inteipreted as evolutional forms called norms (1971.1972). The most probable reason of such aberration was the environmental stress accompanied the catastrophic climatic changes in the Late Permian resulted from the high volcanic activity (Foster. Afonin. 2005).
