Abstract

SummaryChlorine is estimated in nine hornblendes (0·13–1·12%) and nine biotites (0·19–0·62%) from the Kondapalli charnockites for the first time, using the electron microprobe. The data obtained suggest that these Kondapalli minerals are unexpectedly and unusually rich in Cl, which is well equilibrated in the five available coexisting hornblende-biotite pairs.
