Geological cross-section A–A'. A southwest to northeast section from the Seagull intrusion, across the Black Sturgeon River, to Magee Lake.

Geological cross-section B–B'. A south to north section from the Seagull intrusion, through the Disraeli intrusion, to Muskrat Lake.

SOURCES OF INFORMATION Base map information derived from the Ontario Land Information Warehouse, Land Information Ontario, Ontario Ministry ofNatural Resources, scale 1:20 000.

INTRUSIVE CONTACT Clastic Metasedimentary Rocks a The rock unit codes for this legend were designed for use with a database of geoscience information related to the Lake Nipigon Region Geoscience Initiative. As a result, not all codes used in the database are in this legend, and only major rock units are shown on the cross-sections.b Predominantly metasedimentary rocks, but large areas underlying most of the cross-sections probably contain varied amounts of hornblende granite, muscovite granite and the biotite tonalite suite.
