STRATIGRAPHIC AND PETROLOGIC EXAMINATION OF METASEDIMENTARY ROCKS AT CHIMNEY MOUNTAIN, NEW YORK
Rock samples were collected and turned into thin sections. They are to be analyzed for mineral composition and abundance in each of the layers. The apparent metasedimentary sequence dominantly alternates between metasandstone and psammitic layers. The entire sequence may be several meters thick, and is completely exposed at the site. Further study may involve geochronology. The geochronologic study will provide information on the timing of the metamorphism and the age of the sedimentary source with analyses of zircon rims and cores respectively. Determination of the age range of sediments that make up this rock sequence may help to understand if these rocks are related to the erosion of ancient North America, ancient South America, or some other source currently unknown source.
