The limestone at this locality is white and saccharoid, with large rhombohedral crystals of calcspar. |
When nearer the junction it becomes grey, and has a saccharoid structure. |
Mica-schist, gneiss, and saccharoid marble are typical of this class. |
The siliceous beds accompanying the saccharoid limestone have, in short, a character of their own. |
The saccharoid and lamellar, or statuary marbles, belong entirely to primitive and transition districts. |
