Sedimentological evidence of the level and climate changes of Lake Zeribar in the Holocene
Lakes are very interesting sedimentary environments for the study of ancient climate, changes in sedimentary environments and lake level changes. Lake Zeribar is situated in the Zagros Mountains, Kurdistan, Iran. The main purpose of this research is to examine grain size sediments, geochronology and clay mineralogy accumulated in Zeribar Lake in order to check the water level fluctuations, clim...
متن کاملMonitoring of environmental changes of Tabriz plain at Quaternary sediments
Abstract Sediments provide a continuous, sensitive record of changing conditions of environment and processes within plain and in the surrounding plain, thus they contain significant archives of past environmental change on the continents. Valuable informations on regional and global scale patterns of past climate variability in the Azarbayjan region have been documented by numerous paleocli...
متن کاملIran's Climatic Change in the Holocene
Introduction Paleoclimatics studies can respond the many uncertainties about past climate change; an issue that is being studied seriously in the world but less attention has been paid in Iran. The Late Quaternary can be considered as Holocene. Holocene, which spans over 11,000 years ago; In general, it is considered as a period with relatively warm and stable climatic conditions. However, rec...
متن کاملResponse of conifers to UV-B and climate in mountain areas
The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship in trees when the level of ultraviolet-B radiation changes regardless of climate variations. In this study, the consideration was given to the ...
متن کاملBedrock landsliding, river incision, and transience of geomorphic hillslopechannel coupling: Evidence from inner gorges in the Swiss Alps
[1] The formation of inner gorges cut into bedrock has been explained as relief rejuvenation by fluvial incision in response to rapid base level drop, repeated glaciations, frequent pore pressure–driven landsliding focused at hillslope toes, or catastrophic outburst flows from natural dam failures. Prominent inner gorges occur in soft Mesozoic Bündner schist and lower Tertiary flysch units of t...
