    link.springer.com/article/10.1134%2FS1075701510080088 New minerals, shlykovite and cryptophyllite, hydrous Ca and K phyllosilicates, have been identified in hyperalkaline pegmatite at Mount Rasvumchorr, Khibiny alkaline pluton, Kola Peninsula, Russia. They are the products of low-temperature hydrothermal activity and are associated with aegirine, potassium feldspar, nepheline, lamprophyllite, eudialyte, lomonosovite, lovozerite, tisinalite ...

    www.sciencedirect.com/science/article/pii/S0008884620304622 K-shlykovite and Na-shlykovite do not co-precipitate within the same concrete, not even in those exposed to the mixture of KOH/NaOH solution. (2) EDS results show an average Ca/Si ratio of 0.17–0.22 with little variations for all crystalline ASR products independent of exposing alkaline solutions and temperatures.

    www.sciencedirect.com/science/article/pii/S0008884619301139 Na-shlykovite is formed in presence of Ca, when Na is the only alkali. K-shlykovite is formed in presence of Ca when K is the only alkali or at high K/Na ratio of 6.1. A nano-crystalline product labeled ASR-P1 phase is observed in the presence of both K and Na, preferably at lower K/Na ratios 1.0 and 2.3. (ii)
