Ca‐poor Pyroxene Raman Characteristics in H Ordinary Chondrites

In this work we present the zoning of the Ca‐poor pyroxenes polymorphs and its Raman characteristics of crystal within chondrules in H3.3, H4, H5 and H6 ordinary chondrite suite. Applying the Principal Component Analysis (PCA) method to the Raman data and plotting the first and second principal components, we were able to differentiate their petrologic types in four separate fields.
