| Abstract: | Kalsilite—a typical mineral of ore-bearing zones of the Khibiny and Lovozero plutons—was formed after low-Si and high-K nepheline
in one of three ways: (1) by relatively high-temperature replacement of Na with K; (2) due to orthoclase-kalsilite poikiloblastesis
in foidolites and overlapping foyaites; or (3) by replacement of nepheline with zeolite. |
