Variations from dry to aquic conditions in Vertisols (Esplugafreda Formation, Eastern Pyrenees, Spain): Implications for late Paleocene climate change

Menispermaceae from the Cerrejon Formation, middle to late Paleocene, Colombia.

The origin and processes creating the high diversity of plant species in neotropical rain forests and their floristic composition and multistratitified forest structure are still uncertain. Here, we studied one of the most common leaf morphotypes of the Cerrejón flora (middle-late Paleocene, ca. 60-58 Ma), Guajira, Colombia, that contains one of the oldest records of neotropical rain forest flo...

Miospore assemblages from Late Ordovician (Katian-Hirnantian), Ghelli Formation, Alborz Mountain Range North-eastern Iran: Palaeophytogeographic and palaeoclimatic implications

Well-preserved miospore assemblages are recorded from the Late Ordovician (Katian-Hirnantian), Ghelli Formation in Pelmis-gorge at the north-eastern Alborz Mountain The palynomorphs were extracted from siliciclastic deposits which are well-dated by using of marine palynomorphs (acritarchs and chitinozoans). The encountered miospore assemblages consist of 14 genera (28 species: 26 cryptospores a...

Palynomorphs’ response to sea-level fluctuations: a case study from Late Cretaceous – Paleocene, Gurpi Formation, SW Iran

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...

Monitoring of the Vallcebre landslide, Eastern Pyrenees, Spain

In 1996 and 1997 a monitoring network was set up at the translational slide of Vallcebre. Fourteen boreholes were equipped with piezometers, wire extensometers and inclinometers. Since then groundwater levels changes and wire displacements have been automatically recorded every 20 minutes. Superficial displacements have been periodically measured with differential GPS. The monitoring network ha...
