Supplemental Material: Magmato-tectonic links: Ignimbrite calderas, regional dike swarms, and the transition from arc to rift in the Southern Rocky Mountains

Geosphere, December 2019, v. 15, no. 6, 1927-1942, doi:10.1130/GES02068.1, Supplemental Files. Five files of chemical and geochronological analytical data on which the discussion and interpretation of results are based. File 1. Bulk-sample XRF chemical analyses and petrographic summaries: Platoro-Dulce dikes, lavas, and associated rocks. File 2. Inductively coupled plasma mass spectrometry (ICP-MS) analyses: Platoro-Dulce dikes, lavas, and associated rocks. File 3. Previously unpublished chemical analyses of Dulce dikes in southern Colorado and northern New Mexico (E. Landis and W. Hail, Jr., ca. 1972, personal commun.). Analyses by U.S. Geological Survey “rapid-rock” analytical methods (Shapiro, 1967). File 4. Leaching of carbonate with dilute HCl; effects on bulk-sample compositions. A. Dulce Dikes: XRF bulk-sample vs. HCl-leached analyses. B. Dulce dikes: ICP-MS bulk sample versus HClleached analyses. File 5. Summary of ⁴⁰Ar/³⁹Ar age data, analytical methods, and instrumentation.
