Figure 3. Probability Density plot of compiled published bedrock ages and detrital single grain ages <ca. 100 Ma from the a) the Western Alaska Range, Central Alaska Range, and the Wrangell Arc combined (ARZS arcs), b) Western Alaska Range, c) the Central Alaska Range, d) the Talkeetna Mountains, and e) the Wrangell Arc. Data in tables S1, S2, S3, and S4. Kula slab subduction period (100-60 Ma); slab window (60-50 Ma); Pacific slab dominated (50-30 Ma); and Yakutat slab dominated (30 Ma to Recent). Note the Western and Central Alaska Range Arcs have continued magmatism to ca. 25 Ma before a Yakutat slab related cessation in magmatism till arc reinitiation ca. 1 Ma (Trop et al., 2019; Jones et al., 2021; Brueseke et al., 2023).
