Measurements of Silica Excess in Plagioclase in Chondrules from Primitive Carbonaceous Chondrites: Implications for 26Al-26Mg Systematics
Abstract
Chondrules in 3.05-3.1 CCs contain plagioclases that retained silica excess, so that they are suitable for 26Al-26Mg chronology. Moreover, the preservation of silica excess might be more sensitive to secondary processes than Mg diffusion.
