Descrição
Resumo:Allende is an emblematic example of carbonaceous chondrite which fell in Pueblito de Allende (Mexico) in 1969. This meteorite is especially important due to its primitive composition, as one of the main representative examples of the first stages of the Solar System. In this study, a new multianalytical characterization of this chondrite has been carried out, focusing on the mineralogy and geochemistry of the chondrules and the matrix using several techniques: optical microscopy, SEM-EDX, electron microprobe and Raman spectroscopy, the latter has proven to be very useful providing information about the mineral and its structure
