Lorne-Maroon Section

r

The Lorne-lMaroon section includes most of the area of the
drainage basins of Maroon, Hall (Falls), and Douglas creeks,
tributarics-of Kitsuagelluni lake, anc of Fiddler and Lorne creeks,
tributarics of the Skoona. To the south the bouncary of the section
is the contact of a large area of granodiorite. The section has
attracted much attention because of the occurrence of placer gold
in the creoks anc the presence of numerous lode deposits carrying
a high gold content.

The arca is mainly underlain by the bedded rocks of the

younger , secimentary=volcanic group. Conglomerate anc tuff in
places occur in thick, massive beds. There are several separate
conglomerate horizons. Albite-rich intrusives occur throughout
the area. There are dykes, most of which are noarly vertical, and

sills which, following the bedding, have lower dips. Individual j
