Title

SPATIAL DISTRIBUTION ANALYSIS OF LOESS DEPOSITS IN SOUTH AND SOUTHEAST OF CASPIAN SEA

Pages

  7-9

Abstract

 Introduction The word “Loess” has been derived from the German word “Los”, meaning LOESS, which was used for the first time by Leonard in 1824. Regarding the definition of LOESS presented by many authors, aeolian origin and silt fraction dominance have been accepted as the two main attributes of LOESS deposits. Wind- blown deposits of LOESS are characterized by a lack of stratification and uniform sorting and occur as blanket deposits (Bell, 2000). The common mineralogical composition of LOESS deposits is as follows: quartz, feldspars, carbonates, mica and heavy minerals in the silt fraction. According to Pye (1995), four fundamental requirements are necessary for its formation; a dust source, adequate wind energy to transport the dust, a suitable accumulation area, and a sufficient amount of time.
