Why was the data set created?

Jumbo Dome is not well studied and these samples plus the three analyses from Albanese (1980) represent the known total of published whole-rock geochemical analyses for this volcanic feature.

How was the data set created?

1. From what previous works were the data drawn?

   Albanese, Mary, 1980 (source 1 of 2)

2. How were the data generated, processed, and modified?

   Date: 2011 (process 1 of 3)

   Modern data - Rock samples from two separate trips to Jumbo Dome (2005 and 2011) were analyzed for major and trace elements by x-ray fluorescence (XRF) and inductively coupled plasma-mass spectrometry (ICPMS) at Washington State University's Geoanalytical Laboratory in Pullman, WA. Geochemical values were imported into the Alaska Volcano Observatory geochemical database.

   Date: 2011 (process 2 of 3)

   Legacy data - Accompanying tables also include whole-rock data from Albanese (1980). These samples were analyzed by XRF at University of Oregon, Eugene, OR. Geochemical values were retyped and imported into the Alaska Volcano Observatory geochemical database.

   Data sources used in this process:

   • Albanese, Mary, 1980

   Date: 2015 (process 3 of 3)

   Data compilation - Analytical and location records for both datasets were exported from the Alaska Volcano Observatory geochemical database and compiled.

   Data sources used in this process:

   • Cameron, C.E. and others, 2014

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   XRF and ICPMS analyses were performed following the methods of Johnson and others (1999) and Knaack and others (written commun., 1994). Whole-rock oxides are normalized to 100 percent; all iron is reported as FeO. All intensity values were reduced using a single calibration file to decrease interbatch analytical variations. The precision of the results is dependent on both value measured and analyte; data shown here are as provided by the analytical lab; not all figures may be significant. Accompanying tables also include whole-rock data from Albanese (1980). These samples were analyzed by XRF at University of Oregon, Eugene, OR. See accompanying report for a complete reference list.

2. How accurate are the geographic locations?

   Location data for 2011 samples were collected with handheld GPS. Albanese (1980) did not specify location coordinates or provide detailed sample information. Reported location coordinates for these samples are estimations. Latitude and longitude are reported in the WGS84 datum.

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   Jumbo Dome is not well studied and these samples plus the three analyses from Albanese (1980) represent the known total of published whole-rock geochemical analyses for this volcanic feature. Albanese (1980) did not specify location coordinates or provide detailed sample information.

5. How consistent are the relationships among the observations, including topology?
