The Ice River igneous complex, exposed in the
southern part of Yoho National Park in the Field area, British
Columbia, is an asymmetrical laccolith made up of several
varieties of undersaturated alkaline igneous rooks. Nepheline-
sodalite syenite and urtite, two of the major types, are
described.
Several theories on the origin of undersaturated
alkaline igneous rocks are discussed and it is concluded that
Daly’s limestone syntexis theory best explains the origin of
the Ice River complex.
In the vicinity of Garnet Mountain and Aquila Ridge,
the north-west extension of the laccolith has contact
metasomatised enclosing limestone and limestone inclusions.
The mineralogy and petrology of several extensive skarn zones
which carry pyrochlore and radioactive minerals are described.
The concentration of certain elements in alkaline igneous rooks
is considered and the, addition of Na, K, Cb, Zr and others to
Ice River limestone is described. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
