Natural science}, month = {2016-10-28}, note = {The olivine sand from Kawashiri Beach was studied by chemical and X-ray analyses. At least six groups of olivine are mixed in the olivine sand in this region, and they are classified according to the composition of the silicate-melt inclusions in them. The composition of the olivine sand ranges from Fo_70 to Fo_75, and the sum of the Mn_2SiO_4 and Ca_2SiO_4 content is less than 1 (mol %). These crystal chemical data for the olivine sand not only provide basic mineralogical information about it, but they also help us to estimate the origin of it.}, pages = {45--53}, title = {Olivine sand from Kawashiri Beach in Kagoshima, Japan}, volume = {52}, year = {} }
