Goishi Coast, hall ka sakikakuiwaiwamyaku

We observe breeding of the Japanese Islands

Chert dyke of hall ka saki is near small peninsula extending to the south from the west Tachi district of matsusakihanshimaseisoku, and it is appointed to natural monument of country. (access is difficult by subsidence now.)
It is stratum which sand and mud deposit in geological feature of dyke neighborhood in turn in 130 million years ago (the Cretaceous in the first half of the Mesozoic), and was enacted, but there is there crack diagonally, and it is said that rich rock deposits to for silicon later, and there was in the crack.
Stratum from to (the Cretaceous in the first half of the Mesozoic) at the time is distributed over southern (mainly Ofunato, Sumita, Rikuzentakata, Kesennuma) of Kitakami Mountains continually 130 million years ago from (the Paleozoic era shiruru period) at the time 440 million years ago when there was southern northing zone in the north edge of huge continent gondowana.
As there are extremely few places that can observe stratum of these times in succession in Japan, it is valuable at all in knowing breeding of the Japanese Islands.
We can know environment that there was on Asanami - land from abundant fossil to produce at the time.
We can see Permian stratum in city area from the Silurian in the Paleozoic era in Ofunato market day.
