抄録

Kanagawa Prefectural Museum of Natural History has reposited surface peel and moulage specimens collected from real outcrops, mostly of Quaternary volcanic ejecta of Hakone Volcano and related sedimentary layers, as well as other specimens of natural history collections. They are useful for observing tephra and understanding geological processes in laboratories, and are therefore suitable for exhibition and education in museums. Surface peel specimens have the same meaning as natural outcrops. Their clearer colors and textures than the real outcrops could help researchers to recognize unknown tephras or sedimentary structures. Nowadays it is more important to keep those peel specimens as geological evidences, because of disappearance of real outcrops related to road construction, land development or concrete spraying on outcrops. Substantial collection of such peel specimens provides information on geological textures and structures, for example about volcanic fall and flow units, turbidite sequence, load cast, slump, liquification, small-scale deformation structures such as fault and joint, etc., and can be repeatedly examined in related sciences. Collection building and database of such specimens are also meaningful for natural history researches.
