方解石(Na，O，Al，0，4SiO，2HZO)由于易于合成(第11部分)，已被用作在可再生和相对容易获得的条件下高产率地制备矿物和矿物型化合物的起点。方沸石(或白榴石，Ei，O，A1，0，4SiO)已在水热作用下转化为霞石、橄榄石、鼻石、方钠石、钾长石、角闪石、α-辉石，以及各种没有自然生成对应物的物种。它们包括在第一部分中描述的锂沸石T，I，O，A1，0，2Si0，4HZO，沸石化合物K20，A1，0，3Si0，3H20，以及含有插层氯化钾或溴化钾和氯化钡或溴化物的四种矿物型化合物。盐通常可以用水热法提取，有时需要重结晶。给出了这些物种和其他物种的形成条件以及光学和X射线数据。方解石和白榴石的许多变质作用可以在不同条件下逆转，从而实现这些矿物与其他物种之间的各种双向反应途径。这些途径对于沸石和花岗岩形成的化学以及岩石和土壤形成矿物的共生具有重要意义。
Because of the readiness with which it may be synthesised (Part 11) analcite (Na, O, A1, 0,, 4SiO2, 2HZO) has been used as a starting point for preparation, in high yield, of minerals and mineral-type compounds under reproducible and relatively accessible conditions. Analcite (or leucite, Ei, O, A1, 0,, 4SiO2) has been converted hydrothermally into nepheline, cancrinite, nosean, sodalite, barium felspar, potash felspar, kaliophilite, kalsilite, hieratite, a-eucryptite, and various species without naturally occurring counterparts. These include, idev al., a lithium zeolite, T, i, O, A1, 0,, 2Si0,, 4HZO, described in Part I, a zeolitic compound, K20, A1, 0,, 3Si0,, 3H20, and four mineral-type compounds containing intercalated potassium chloride or bromide, and barium chloride or bromide. The salt could usually be extracted hydrothermally, sometimes with recrystallisation. Conditions of formation, and optical and X-ray data, of these and other species have been given. Many of the metamorphoses of analcite and leucite can be reversed under different conditions, so that various two-way reaction paths between these minerals and other species can be realised. Such paths have significance for the chemistry of zeolite and of granite formation and in the paragenesis of rock and soil-forming minerals.
