Comparison of single grain U–Pb zircon analyses from the Mount Givens Granodiorite (blue; Frazer et al. 2014) and the Fish Canyon Tuff (red; Wotzlaw et al. 2013). Horizontal axis sequences analyses from youngest to oldest for one Fish Canyon Tuff sample and twelve Mount Givens samples distributed throughout the intrusion. These two rock units are comparable compositionally and likely comparable volumetrically. The scale for both samples is the same, but note the difference in absolute age for the Mount Givens Granodiorite (left axis) and Fish Canyon Tuff (right axis). Maps show outlines for the Mount Givens pluton and the La Garita caldera (the source of the Fish Canyon Tuff) at the same scale. Inset: A typical zircon from the Mount Givens Granodiorite. The Mount Givens Granodiorite records an age range that is over an order of magnitude greater than that for the Fish Canyon Tuff.

Figure 9. (A) Cape Horn roof pendant and underlying Mount Givens pluton. Roof rocks (Kings Sequence metasedimentary rocks) are the darker colored and more jointed rocks in steeper face seen in upper right part of photo. They also can be seen along skyline to the left. The Mount Givens granodiorite is the lighter colored rock seen in center of photo. Roof rocks are sharply truncated at the base by a highly discordant “cookie-cutter” pluton contact (behind trees in lower right). Two, vertical, several-meter-wide granodioritic dikes in center of photo intrude the northwest-trending, steeply dipping wall-rock cleavage of the roof rocks. A similar dike can be seen just above the large tree to the left; this dike cuts a cupola of roof rocks. These relations show the discordant nature of the roof and the control played by crustal anisotropy. (B) Folded Mount Givens dike in Cape Horn pendant. Thin sections show that the dike does not exhibit solid-state deformation, indicating synintrusive contraction strain in the wall rocks. Hammer to upper right is for scale. (C) Folded Mount Givens dike in the Cape Horn pendant. Note dispersal of magma in the fold hinge. No solid state deformation occurs within this dike. Hammer in middle of photo is for scale. (D) View looking southeast, showing the contact between the Mount Givens pluton (lighter rocks on right) and Jurassic-Triassic metavolcanic rocks in the Mount Goddard pendant (darker rocks on left). Contact transects 1200 vertical m of relief, indicating a vertical, eastern pluton margin.

Figure 11. Simplified schematic cross sections showing sequential stages of magmatism in northern lobe of Mount Givens pluton. Vertical exaggeration is 2×. E—equigranular facies; MC—megacrystic facies; CM—Cow Meadow granodiorite. (A) Plan view showing northeast-southwest cross section line (X–X′) for B–E. (B) Emplacement of stage 1 equigranular magma (E) due to floor downdrop. (C) Emplacement of stage 2 megacrystic magma (MC) due to floor downdrop. (D) Stage 3 inflation (doming and expansion). (E) Stage 4 rupturing and ring diking of stage 1–2 carapace with cantilever model. Three possibilities are shown: internal redistribution within chamber, leap-frogging of magma to form a shallow, cantilever-type pluton above the Mount Givens pluton, and an asymmetric caldera. Dotted line represents present-day erosional level. (F) Plan view showing northwest-southeast cross-section line (Y–Y′) for (G). (G) Diagram shows cumulative effects of four-stage emplacement history. Pins show foliation dip. Dotted line represents present-day erosional level.

(B) Mount Givens pluton, with horseshoe-shaped ring dike in northwestern portions, interpreted as possible trap-door caldera subsidence (McNulty et al., 2000). E—equi-granular facies; MC—megacrystic facies; CM—Cow Meadow granodiorite.(C) Schematic cross section of foliation trends through Cretaceous El Pinal pluton, Baja California, interpreted as the result of caldera subsidence of roof rocks (Duffield, 1968). (D) Subhorizontal foliation in Jurassic Canyon Creek pluton (Davis et al., 1965), as recorded by flattened mafic inclusions. (E) Diagram illustrating contrasting fabrics in margin and interior of Canyon Creek pluton; plagioclase and hornblende define foliation throughout, but randomly oriented large biotites in pluton interior are interpreted as indicating postflowage crystallization. This pluton has a similar overall cross-section geometry as the El Pinal intrusion (C).
