Zonal structure in plagioclases

, 1926
The purpose of this paper is to record the results of a series of observations on zonal plagioelases made with the aid of the Fedorowstage. Some of these results may add to our present knowledge of zonality in general. It is necessary, first of all, to give a definition of what we mean by zonal structure.
