OCR PDF of supplemental information for the Meta-Pelite Suite, Shelburne, Nova Scotia collection. This file outlines the descriptions of every sample in suite as well as providing geologic context to the area and the suite itself.
Macroscopic: Low-grade metamorphic (zeolite facies) black siltstone with idiomorphic pyrite porphyroblasts. Microscopic: Very fine grained quartz and muscovite with large pyrite phenocrysts. Thin section picture in XPL unless noted in the picture…
Macroscopic: Slate (low grade shale metamorphism) samples with visible thin black beds. Samples were found interbedded with siltstones represented by sample NS-1. High angle between bedding and cleavage. Microscopic: Very fine grained quartz,…
Macroscopic: Argillite bearing spessartine garnet formed through reaction with the surrounding rock during metamorphism. Microscopic: Abundant medium-sized garnet phenocrysts within a very fine grained matrix. Thin section pictures in XPL unless…
Macroscopic: Biotite, muscovite schist. Parts of the outcrop are migmatic as a result of intrusion by various phases of the Port Mouton Pluton. Microscopic: Coarse grained biotite, muscovite and quartz. Thin section pictures in XPL unless otherwise…
Gneiss from the Bethlehem Gneiss series. Thin section contains biotite, plagioclase, alkali feldspar, and quartz. Hand sample shows slight discoloration (orange tinge) from weathering of an iron oxide, a high concentration of biotite, quartz, and…
