A number of the rocks which fall in nordmarkase and pulasku.se carry small
amounts of nephelite, so that they have been called nephelite-svenites, but not
enough, according to the classification proposed, to place them in the order
russare.

NEPHELITE BOCKS. In the norms of the foregoing rocks small quantities of
nephelite appear. These mark a transition from the syenites and trachytes proper
to the phonolites and nepheline syenites, in which the lcnad minerals replace the

NEPHELITE BASALT AND ALLIED ROCKS. In the Hitchcock collection are
several rocks which in the current nomenclature must be called nephelite basalts,
although this name unduly emphasizes a very subordinate constituent. It is
probable ...

The constitution of the natural silicates
THE NEPHELITE TYPE. If, now, we start out from the normal aluminum
orthosilicate the first and simplest replacement possible is that of a single
aluminum atom by three monads, giving a compound of the general formula Al3(
Si04)3R'3.

Nephelite Syenite (PLATE 20) Nephelite syenite is more than a variety of syenite,
for it shows some of the variations that the true syenites present. It is
characterized by the presence of nephelite and generally sodalite, in addition to
the ...
