| Summary | (Plain Language Summary, not published)
This publication presents data to support age interpretations for volcanic and plutonic rocks from the Woodburn Lake area, north of Baker Lake in the
Kivalliq district of Nunavut. The rocks form part an ancient volcanic sequence that formed 2.7 billion years ago and host important gold deposits (e.g. Meadowbank mine). The ages were determined using natural radioactive decay of Uranium to Lead
within the mineral zircon, an important accessory mineral that crystallized at the same time as the rock. The data can be used to understand when and how the rocks in this area formed and how they may correlate to other units in the area in order to
develop better geological models. |
