This paper specifies the whole course that sediment cleavage
function can not reflect sediment function , still exists sediment
mixture function on the contrary. After analyzing the
transformation relation between the element of sediment area rock
with the element of denudation area original rock , as well as
realizes that whether sediment cleavage function or sediment
mixture function is priority ,the element of sediment area rock is
inharited in sediment course ,reflects the character of denudation
area original rock element in a certain extent , its sediment
sequence opposes to original statum sequence ,to sum up this is
sediment reverse order disciplinarian. This paper indicates that
this disciplinarian has direction meaning to forecast deposited
stratum distribution and to direction stratum contrastion partition
and to help locale decision-making and so on.
