Late Oligocene–Early Miocene paleosols of distal fluvial systems, Ebro Basin, Spain
The study of paleosols can be a vital tool in the paleoenvironmental interpretation of continental deposits because their physical and chemical characteristics are a reflection of variations in aspects of soil formation. Changes in paleosol characteristics can be used to determine the architecture and nature of parent material, paleosol maturity, topography, climate and soil-forming organisms (...
متن کاملGEOLOGICAL NOTE Global Aridity during the Early Miocene? A Terrestrial Paleoclimate Record from the Ebro Basin, Spain
Paleosols are an important tool in the paleoclimatic and paleoenvironmental interpretation of continental deposits and can provide a high-resolution proxy for paleoclimate. Results from geochemical climofunctions applied to Early Miocene strata exposed in the Ebro Basin, Spain, demonstrate that mean annual precipitation was the dominant control on paleosol type and indicate that the paleoclimat...
متن کاملLower Tithonian ammonites from the Chaman Bid Formation in northeastern Iran, Koppeh-Dagh Basin
The type section of the Middle and Upper Jurassic Chaman Bid Formation is in the western Koppeh Dagh Basin (Northeast Iran). It is unusually thick and contains a rather rich ammonite fauna, ranging from Bathonian to Tithonian. The ammonites described here come from a 134-m-thick interval in the upper part of member (D) in the middle part of the formation, consisting of an alternation of grey li...
متن کاملThe first megatheropod tracks from the Lower Jurassic upper Elliot Formation, Karoo Basin, Lesotho
A palaeosurface with one megatheropod trackway and several theropod tracks and trackways from the Lower Jurassic upper Elliot Formation (Stormberg Group, Karoo Supergroup) in western Lesotho is described. The majority of the theropod tracks are referable to either Eubrontes or Kayentapus based on their morphological characteristics. The larger megatheropod tracks are 57 cm long and have no Sout...
متن کاملTRACE ELEMENT STUDY ON THE MIXED CARBONATE-PYROCLASTIC SEDIMENTS (LOWER MIOCENE, CENTRAL BASIN, IRAN)
Geochemical investigations have permitted the refinement of the environmental interpretation of the f-Member of the Qum formation, Central Basin, Iran, which has been established through detailed microfacies (MF) analysis. The analysis revealed that the f-Member carbonates consist of eight distinct microfacies designated by the letters A through H. On the basis of petrographic characteristi...
