| Through the years, articles on datolite have periodically appeared in mineral magazines. |
| The datolite from this locality also showed traces of platinum but in insufficient quantities to be the coloring agent. |
| Microscopic examination of datolite nodules from a number of localities shows that native copper is probably the most common impurity. |
| Shallow pits were excavated, and several small datolite nodules were recovered that had a somewhat almond shape and a dark black chloritic rind. |
| This unique form of datolite hails from the legendary Lake Superior copper deposits, home to the world's largest occurrence of native copper. |
| Porcelaneous datolite occurred in the amygdaloidal lodes as veins, vesicle filling, and nodules. |
