Table S1. Composition of olivine in Vigarano. Shown are means for each chondrule and standard deviation of the averaged data set (n analyses; dividing by √n yields the uncertainty of the mean). If n=1, the analytical error (1 sigma) is given instead. Concentrations are in parts per million (1 ppm = 1 µg/g) and are LA-ICP-MS data except for Fe (EMPA). b.d. = below detection limit, n.a. = not available. Unless otherwise noted, chondrules are type I.

Table S2. Composition of olivine in the CR chondrites Renazzo and Acfer 187 Shown are means for each chondrule and standard deviation of the averaged data set (n analyses; dividing by √n yields the uncertainty of the mean). If n=1, the analytical error (1 sigma) is given instead. Concentrations are in parts per million (1 ppm = 1 µg/g) and are LA-ICP-MS data except for Fe (EMPA). b.d. = below detection limit, n.a. = not available. Unless otherwise noted, chondrules are type I.

Table S3. Composition of low-Ca pyroxene in Vigarano and Renazzo. Shown are means for each chondrule and standard deviation of the averaged data set (n analyses; dividing by √n yields the uncertainty of the mean). If n=1, the analytical error (1 sigma) is given instead. Concentrations are in parts per million (1 ppm = 1 µg/g) and are LA-ICP-MS data except for Fe (EMPA). b.d. = below detection limit, n.a. = not available. Unless otherwise noted, chondrules are type I.

Table S4. Composition of Ca-rich pyroxene in Vigarano and Renazzo. Shown are means for each chondrule and standard deviation of the averaged data set (n analyses; dividing by √n yields the uncertainty of the mean). If n=1, the analytical error (1 sigma) is given instead. Concentrations are in parts per million (1 ppm = 1 µg/g) and are LA-ICP-MS data except for Fe (EMPA). b.d. = below detection limit, n.a. = not available. Unless otherwise noted, chondrules are type I.

Table S5. Composition of mesostasis in Vigarano, Renazzo and Acfer 187. Shown are means for each chondrule and standard deviation of the averaged data set (n analyses; dividing by √n yields the uncertainty of the mean). If n=1, the analytical error (1 sigma) is given instead. Concentrations are in parts per million (1 ppm = 1 µg/g) and are LA-ICP-MS data except for Fe (EMPA). b.d. = below detection limit, n.a. = not available. Unless otherwise noted, chondrules are type I.

Table S6. List of analyzed chondrules. Shown are classification, modes, and the diameter of the equal-area disk. (*) denotes largely altered mesostasis and (**) indicates that the chondrule lies at the edge of the section so that its size is underestimated.
