The Matto submerged forest was found in spring of 1998 as stumps, roots and erect trunks from the continental shelf at depth between 20 and 30 m, and in 2 to 3 km off the recent marginal area of the Tedori-gawa alluvial fan at Hama-sogo and Kurabe, Matto City, the Hokuriku region, Central Japan.

The spatio-temporal distributions and tectonic environments of the Meso-Cenozoic igneous rocks in SE China and Japan are discussed mainly,as well as their similarities and differences are summarized in the paper.

In this paper, we make a comparative analysis and correlation test for the seismic activities in the South Japan and the Ludong-Huanghai block (a secondary tectonic unit in the North China) and approach the relationship between the energy release processes of these two areas by using co-integration analysis and Granger causality test for the time series of random variables.
