The purpose of this study is to evaluate the utility of hyperspectral mapping of alteration minerals in drill core samples using the Hy Spex SWIR-320m hyperspectral camera that covers the 1300ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“2500 nm (SWIR) spectral range.A series of representative samples, including pegmatite, pelitic gneiss, and sandstone, from the area around the Cigar Lake uranium deposit (Athabasca Basin, Saskatchewan, Canada) were analyzed by SWIR reflectance spectroscopy and optical microscopy.Geological analysis relies mainly on chemistry, physics and mathematics. a'a' lava - basaltic lava characterized by a rough or rubbly surface composed of broken lava blocks called clinker.
accrete - To add terranes (small land masses or pieces of crust) to another, usually larger, land mass. age - A unit of geological time shorter than an epoch, usually lasting several million years.
- INTRODUCTION The level of carbon dioxide has increased tremendously over the past few years by nearly 40%, that is from approximately 280ppm in preindustrial times to 384ppm in 2007(Solomon 2007).
Nearly one third of anthropogenic carbon dioxide is being absorbed by the oceans today(Science Daily, May 24, 2008) .
The mineral maps highlight the mineralogy and the main petrographic textures such as foliation, bedding, veins, and the geometry of pervasive alteration.
This study offers new perspectives for the use of this method in mineralogical analysis of drill core samples and the characterization of hydrothermal alteration.
