It was established that mineralogical composition of coastal deposits was a result of provenance and its hypergenous changes, transformation of material within transit zone, and accumulative conditions of inshore zone. Contents of stable minerals increase in deposits of the inlets confined to mouths of the small streams and in horizons of the sections, formed during regressive phases. Unstable minerals amount is higher in deposits of inlets, confined to mouths of the large river. The clay mineral fraction of shelf sediments consists mostly of illite. Authigenous pyrites dominate in deposits of ria bays, lagoons and relict lakes, formed during transgressive phases. Volcanic glass, found in deposits, is product of Holocene eruptions of Baegdusan (Baitushen) Volcano.展开更多

The new government in Japan is now headed by DPJ and its alliance–Social Democratic Party and People's New Party, substituting for LDP-Komeito coalition government, an alternation of two conservative parties, though not in a strict sense of the two-party alternation. The election intensified the conservative politics in general, though different from the hawk conservative force in the post-cold war period. The Japanese political currents see a trend of 'de-rightwardization'. This will help to improve Japan’s relations with its Asian neighbors. Yukio Hatoyama calls for building 'fraternity society' and fostering 'fraternity' spirit in diplomatic affairs. He is for the view of attaching equal importance to U.S. and Asia.展开更多
