the forumad ophiolite in the northwestern part of the sabzevar region has embraced the largedepleted harzburgites and dunitic bodies associated with podiform chromitites. in some deposits, chromitegrains have segregated as nodules. the stretched shape along with high cr2o3 and tio2 contents are thecharacteristics of the nodules. compared to the other tethyan nodular chromites, the forumad nodul...

The study of a rich Middle Oxfordian arnrnonite succession from Kachchh CW India) supplies new evidence to support the open biogeographic connections between Submediterranean and lndo - East-African Provinces. studied assemblage is precisely dated as Upper Transversarium Zone, (Middle Oxfordian), on basis representatives Perisphinctes Larche­ria , this finding being first record West-Europe...

Abstract The paleoenvironmental and paleogeographic development of the Norwegian–Greenland seaway remains poorly understood, despite its importance for oceanographic climatic conditions Paleocene–Eocene greenhouse world. Here we present analyses sedimentological paleontological characteristics deposits (between 63 47 million years old) in northeast Greenland, investigate key unconformities volc...

In the past 10 years an abundance of new models aimed at finding a better or even the ultimate solution for the structure and evolution of the Mediterranean Tethys have been published. These models are based on new geophysical (mainly paleomagnetic) results, refined stratigraphic and facies data, and sometimes even on detailed geochemical analyses. They were constructed with the help of paleaog...
