This data release presents the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) from surface exposures of the Dora Bay igneous complex (DBIC), located in the southern part of Prince of Wales Island, southeastern Alaska. The DBIC is Early Jurassic in age (Bala and others, 2014) and is U-Th-heavy rare earth element (HREE)-enriched like the Bokan Mountain intrusive complex 30 km to the south (Philpotts and others 1998; Dostal and others, 2011; Taylor and others, 2016; 2017). However, the DBIC is significantly less-well-mineralized and is under-explored due to complicated private land status issues. HREE-enriched eudialyte-bearing pegmatites and felsic dikes have been discovered in numerous places within and along the margins of the pluton and extending up to 1 km into the country rocks as well as molybdenite and iron oxide mineral occurrences at its margins (Barker and Mardock, 1990; Philpotts and others, 1993; Taylor and others, 2014). Uncertainty of global REE supply and the subsequent spike in prices in 2008 resulted in renewed exploration at the DBIC by Avalon in 2010 and Sealaska Native Corporation in 2014-2015 (Buckley and Taylor, 2014). The DBIC was included in recent studies by the USGS Mineral Resources Program as part of an effort to understand the distribution of REE resources in the United States. This data release provides the analytical results of 54 rock samples collected by the authors during a site visit to the DBIC in June-July 2015. The samples represent transects along the major exposed ridgelines and outcrops within the complex. They provide a measure of the REE abundances and their variation throughout the complex as well as material for detailed isotopic and mineral chemistry studies. The samples were analyzed for 60 major and trace elements by inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS)after a sodium fusion digestion and for major elements using wavelength dispersive x-ray fluorescence spectrometry (WDXRF). This data set is provided for future use in geologic, exploration, and environmental background studies of the DBIC.
