A summary of progress in mineralogy and petrography ...
Another rock very characteristic of the region is called laurdalite. This is a coarse-
grained nepheline-syenite, with or without olivine; It contains more nepheline and
sodalite than does laurvikite, and the former mineral is porphyritically ...
William Shirley Bayley, 1889
This use of it excludes such types as Litchfieldite, Laurdalite, Lujaurite, and many
others, but includes Brbgger's and Derby's Foyaites. At the same time it appears
probable that the majority, if not all, of those authors who have used foyaite as ...

The dosodic laurdalo.se includes, besides the typical laurdalite, the tinguaite and
mica-syenite of Hedrum. the soda-minette of Hao. with some other nephelite-

... diopside and aegirine in large quantities. The eleolite frequently changes into
analcite. The rock, though quite acid, as the analysis shows, is nevertheless an
eleolite syenite, closely similar to laurdalite.2 SiO, Al20:i Fes02 CaO MgO K20 ...

Laurdalite, beumite, nepheline porphyry, foyaite, and hedrumite are the nephelite
rocks described in this memoir. A remarkable rock found in Dimgannon Township

These were followed by a series of syenites: laurvikite, mics.syenite, and
nephelite-syenite, laurdalite. The laurvikite, or augite-syem'te, occupies a large
area and has marginal facies that are porphyritic and grade into
rhombenporphyry.

The igneous rocks are essexite, nordmarkite, and laurdalite, together with various
associated dykes. Dresser states that the several types of rock resulted from three
separate intrusions, the essexite coming in first, with the nordmarkite later ...
