Abstract
We need the amounts of 26Al productions in meteorites in space to determine the terrestrial ages of meteorites. The amount of 26Al productions were estimated by major elemental compositions of meteorites or cosmic-ray fluxes.
Here we present a new production rate of 26Al that is applicable for not only chondrites but also HED meteorites. We estimated the amount of productions of 26Al by major elemental compositions in meteorites based on the correlation between 26Al contents and elemental compositions in nineteen meteorite samples fallen recently.
