Abstract
Some of the garnets in eclogites within the quartzo-feldspathic gneisses of Nordfjord, West Norway, are zoned with higher calcium, iron and manganese in the cores and more magnesium at the rims. The zoning is discussed in terms of the apparent distribution coefficients of Fe2+/Mg between garnet and clinopyroxene (which will be aberrantly high for the garnet cores) and in terms of the metamorphic evolution of the eclogites.
