Number,Letter,Variable,Explanation

1,,N,Sample number

2,,Sample,Sample name/label

3,A,Lithology,Lithologic description available for the sample

4,B,Location/Body-Name,Description of the location or name of the igneous body if available

5,C,Latitude,Coordinate information for the sample

6,D,Longitude,Coordinate information for the sample

7,E,Location-Type,"Information used for finding coordinates for the samples. The three possible values are: “GPS”, “Figure-Point”, and “Figure-Polygon”. Samples with a location in a coordinate system were transformed to decimal degrees (WGS84) and classified as “GPS”. Samples individually identified in a georeferenced geologic map were approximately located after georeferencing the map in Google Earth or ArcGis (“Figure-Point”). Samples identified with a polygon in a georeferenced map (through age, body name or unidentified sample locations), but without more detailed information were approximately located in the middle of the corresponding polygon after georeferencing the map in Google Earth or ArcGis (“Figure-Polygon”). Precise “GPS” locations were obtained for 358 analyses, and approximate locations were obtained for 428 analyses"

8,F,Reference,Reference information for the geochemical data

9,G,Age-Approximation,"Information used for finding the age of each sample. The three possible values are: “Age-Approximation”, “Age-number”, and “Age-Error”. “Age-approximation” corresponds to the age information from original paper or from an additional reference detailed in the “Reference-Age” column. “Age-number” corresponds to the age reported in the original paper or previous compilation, or to the average age calculated from a given age range. “Age-Error” corresponds to the error presented in the original paper or previous compilation, or to half of the age range"

10,H,Reference-Age,Reference for the age of the sample

11,I,Age-number,Numeric value for the age of the sample

12,J,Age-Error,Numeric value for the error associated with the sample

13,K,Method,Method used to obtain the geochemical data. This is based on the original reference.
