The matrix of a meteorite often contains metals, predominantly iron. The matrix of Weldona has a high metal content, while Barratta has much less metal in its matrix. Their classification reflects these differences: Weldona is an H-chondrite ("H" for high metal) and Barratta is an L-chondrite ("L" for low metal).
