Includes bibliographical references (p. 5-6). “This data Open File provides tables of mineral analyses determined by electron microprobe from unique samples of igneous rocks in offshore petroleum exploration wells, mostly of Triassic and Cretaceous age, but also including some Paleozoic basement rocks and a few comparative rocks on land. Most analyses are from clinopyroxenes, amphiboles, feldspars, biotite, and olivine and their alteration products. Excel data files are provided in addition to this report”--Abstract, p. 4. gccst Igneous rocks Mineralogy Electron probe microanalysis Piper, D. J. W. Imperial, A. Canada. Natural Resources Canada.
