They found the nepheline - albite eutectic to be at 1068°C at Ne:4Ab76 (by
weight). Bell & Roseboom (1969) determined phase relations at 32 and 40 kbar (
Fig. 146(b) and (c)). There have been many studies of the reaction jadeite =
albite + ...

174) which can crystallize either in a high- or a low-temperature form (high- or
low anorthite and high- and low-albite). High- plagioclase is restricted to volcanic
rocks whereas low-plagioclase is found in plutonic and meta- morphic rocks.

The need to select M-l, M-2, D-l, and D-2 so that they can be represented as
vectors in the four-dimensional space of the sample vectors is analogous to the
need to describe the plagioclase compositions in terms of combinations of albite
and ...

Albite schists in the southwestern part of the Dalra- dian series in Scotland and
northeastern Ireland are associated with limestone and chlorite-epidote schists.
Like the albite schists of York County, Pa., they have a relatively high soda
content.
