| Outline of Final Research Achievements |
The present study is focused onto the natural occurring jadeitites, especially on the jadeitite veinlets cutting across the jadeitite or its related rocks (e.g., albitite and rodingite). The existence of the vein-type jadeitite is considered to be one of evidence for the hydrothermal origin of jadeitite. In the present study, jadeitite veinlets cutting across albitite have been newly found from the Ohya-district, Hyogo Prefecture. The veinlets are consisted of jadeite crystals elongating parallel to the veinlets, whereas the jadeite crystals in the jadeitite veinlets from the other localities (e.g, Tsugaike-district, Nagano Prefecture) elongate perpendicular to the veinlet-wall boundaries. Two types of the jadeitite veinlet, one from the Ohya-district and another from the Tsugaike-district, have been compared and examined in details.
