S. Theodorikas, A STUDY OF K-FELDSPARS FROM THE SERRES-DRAMA PLUTONIC COMPLEX, NORTHERN GREECE, Neues Jahrbuch fur Mineralogie Monatshefte, (8), 1998, pp. 337-353
The variation in the structural state of potassium feldspars from the
Serres-Drama plutonic complex, Northern Greece, from X-ray diffraction
study is discussed. Monoclinic potassium feldspars occur in monzoniti
c rocks, which may have cooled with a much lower volatile content, whi
lst triclinic potassium feldspars occur in quartz monzonite, granodior
ite and granite which probably cooled in the presence of a greater vol
atile content.
