Data related to: Open-system evolution of a crustal-scale magma column, Klamath Mountains, California

Granitic magmas commonly display evidence for some level of interaction
with and/or origins from crustal rocks. There is fundamental debate in the
community as to the processes that control the origins of these magmas and
the potential for their contamination as they pass through the crust. One
approach to addressing these issues involves a combination of detailed
field mapping combined with geochemical analysis of bulk-rock samples and
their constituent minerals. In particular, resolution of debates about
magma origin(s) and contamination processes rely on U-Pb ages of zircon
combined with isotopic data gathered from bulk-rock samples and from
minerals such as zircon. The data presented here consist of U-Pb, Hf, and
oxygen isotope analyses of zircon crystals separated from a major plutonic
complex in northern California: the Wooley Creek batholith and Slinkard
pluton. In addition, data are presented for samples of the metamorphic
rocks that host these intrusions and for xenoliths of these host rocks
engulfed by the intrusions. These data are discussed in the
above-mentioned manuscript. Generation of the data was supported by
National Science Foundation grants EAR-0838342 to C. Barnes and A.
Yoshinobu, EAR-0838546 to K. Chamberlain, and EAR-1524336 to J. Valley.
The WiscSIMS isotope facility (oxygen isotope data) was supported by NSF
grant EAR-1658823 and the University of Wisconsin-Madison. Figure 1
illustrates the locations of plutonic samples analyzed. Table 1 presents
sample locations and rock types. Tables 2–5 present U-Pb ages and Hf
isotope data determined by laser-ablation inductively coupled plasma mass
spectrometry at the University of California-Santa Barbara. Tables 6A–6E
present U-Pb ages determined by SHRIMP-RG (sensitive high resolution ion
microprobe-reverse geometry) at Stanford University. Table 7 presents
oxygen isotope (zircon) data determined by SIMS (secondary ion mass
spectrometry at the University of Wisconsin-Madison.
