DESCRIPTION:Abstract: Segregation in mixtures of granular materials is a t
 opic which is \nof interest to a broad range of scientists from physicists
 \, to geologists \nand engineers. The phenomenon involves the spontaneous 
 de-mixing of an \ninitially mixed state into its constituent components un
 der the action of \nflow. We will discuss these issues and present the res
 ults of experimental \ninvestigations into particle segregation in a binar
 y mixture which is \nsubject to periodic horizontal forcing. The initially
  mixed state undergoes \na surprising selforganization process such that t
 he two constituent \ncomponents separate to form patterned structures. The
  pattern formation \nprocess shows critical dependence on the concentratio
 n ratio of the \nmixture. Detailed features of the observations appear to 
 be in accord with \nnotions from equilibrium phase transitions.\n
