Open File NFLD/2377, Part A, (Kerr et al., 1994) listed historic geochemical data for numerous granitoid and related rocks collected and analyzed by the Newfoundland and Labrador Geological Survey between 1974 and 1990. The data listed in Open File NFLD/2377 used an SPSS® format which required translating coded values for a variable into meaningful names. The data was also in an ASCII text format. This new version has translated these values into names which are therefore more easily understood by the reader. The Microsoft Excel ® format of the new version of the datasets is currently more commonly used and therefore makes the data more easily accessible by users.

This web-page version of this open file is a slightly simplified version of the CD version. The CD version has an additional sheet which is a compilation of the other five data sheets.

The Microsoft Excel ® format is currently more commonly used and therefore makes the data more useful for researchers wishing to work with the data.

Typographic errors found in the original Open File NFLD/2377, Part A, have been corrected; otherwise Part A is as published in 1994. Part B of Open File NFLD/2377 (Hayes, 1994) is unchanged. It describes the calculations of precision for the original dataset.

The reader is referred to Open File NFLD/2377, Part A, which gives a full explanation of the original dataset and names of variables in printed form.

The variable “Datum” has been added. All locations were determined using the North American Datum 1927. This addition will prevent confusion with locations determined since 1983 which may have used North American Datum 1983 and now being used on newer versions of topographic maps.

As noted in Open File NFLD/2377, Part A, the year the samples were analyzed is indicated. This is generally the year after the samples were collected. However, the samples collected in 1974 were re-analyzed in 1990. These sample numbers have the prefix 45 or 46, e.g., 4640221.
