The sandstones show distinct variations in chemical composition as well as mineralogical one in relation to geologic ages and provinces.The kind and nature of source rocks of sandstones are we11 reflected in such properties of clastic fe1dspars as abundance of total fe1dspars,alkali feldspars/plagioclase ratio and chmical composition. Average chmical composition of the sandstones in Japan are briefly discussed in comparison with those in the world.}, pages = {55--66}, title = {日本の砂岩の化学組成}, volume = {40}, year = {1981} }
