the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

This paper presents a paleoenvironmental reconstruction from palynological analyses of a sedimentary core of Holocene age, drilled at municipality of Garopaba (Santa Catarina), Southern Brazil. A total of 46 samples was collected for palynological analyses in the 450 cm-long core PCSC-3, as also three samples for radiocarbon dating and granulometric analyses. The palynological content includes ...

statistical studies on palynology contents of late cretaceous to paleocene age gurpi formation in a surface section in zagros basin,sw iran indicate changes in abundance, species diversity, ratio of spiniferites to cyclonephelium (s/c), palynological marine index(pmi) values and organic facies. these palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...
