NEPHELINE AS A SOURCE OF AMORPHOUS PHASES IN SUPERGENE PROCESSES

Abstract

In order to specify the effect of technogenic factors on the composition of natural waters, the behavior of nepheline particles <0.002 mm in size at a temperature of 18–20°C and pH 7.4–8.6 has been studied. The results obtained show that finely ground nepheline passes into an amorphous phase over a few days or months. The study is based on the data on natural and technogenic water in the area of the Khibiny alkaline pluton.
