Summary

This database consists of lithogeochemical data from 51 samples of igneous rocks collected mainly from the Eastport–St. Brendan’s area, northwestern Avalon Zone, as well as seven from the Isthmus of Avalon, Newfoundland. The database includes brief sample descriptions, location data, field photographs, petrographic descriptions and photomicrographs, as well as major-element and trace-element data for 58 samples of mainly volcanic rocks. The open file data release provides no interpretation of the data. Results and interpretation of the lithogeochemistry of these rocks will be published at a later date.
