Some problems of coastal placers formation at the south-eastern Baltic coast with view to their development during the Holocene

Abstract

The analysis of recent dynamics of sea coast and marine placers location as well as heavy minerals distribution within the productive sand layer when compared with the lagoon coast evolution during the Holocene showed the marine placers formation during the Holocene to be inherited from earlier stages. They are connected with processes of bars and barrier-beaches formation and deep differentiation of debris under condition of relatively closed systems of ingression coasts during the early Holocene. Now they do not receive any noticeable supply any more. Normal component of the load movement remain the leading factor in the placers formation.
