Abstract
Various unmixing phenomena are observed in feldspars from solvsbergites and trachytes. The response to heat treatment of these feldspars is predetermined by the original unmixing processes. The cooling history of some solvsbergites is interpreted on the basis of the feldspar study and additional observations made on xenoliths, and evaluation of time intervals between the eruption of several trachytic flows is offered.
