内容記述 Because the qualities of phosphate rocks produced within the Ryukyu Islands are related to their locations, further research is undertaken on their micro-elements such as zinc and copper.\nIt is found that there are phospahte rocks containing a considerable amount of\nzinc (0.1-0.7%) and that such phosphate rocks without exceptions are produced in\npocket forms on hills near seashores.\nIt is ascertained that there is a positive correlation between the amount of zinc and the amount of iron, aluminium and silicate contained within the rocks. \nFurther, iron and aluminium phosphate rocks being produced within calcium caves, were investigated as well as bat-guano inside the cave. \nIt was found that a large amount of copper (0.6-1.2% in the ash) was contained in the bat-guano.\nVertical sections of the accumulated bat-guano was investigated with a view to understanding the decomposition of the bat-guano with the behavior of copper.It was ascertained that copper becomes soluble and flows out upon the decomposition of the bat-guano without entering into the phosphate rock and that zinc and calcium behave similarly. In contrast. iron, aluminium and silicate tend to remain as phosphate, so that it is clear that iron and aluminium phosphate formed inside calcium caves contain very little copper, zinc and calcium.
