a particularly
attractive geologic
specimen that upon expert examination provides a uniquely or strikingly
well articulated lithographic expression, mineralization, or other geochemical condition

hammer in hand, he moved to carefully separate the country
rock from the sample he knew others in the
office would admire with great enthusiasm. This went far beyond basic bornite; this qualified as genuine pornite!
