A complex system of dykes known as the "V" Intrusive lies about 1.2 km south of the Potash Sulfur Springs complex (No. 117) (Erickson and Blade, 1963, Fig. 4). The dykes, in order of decreasing age, are of malignite, melteigite, microijolite, sannaite, feldspathoidal syenite, pulaskite, alkali syenite, alkali syenite aplite and fluorite-pyrite-silica veins (Steele and Wagner, 1979, p. 395).
