Examples
-
The veins of it are difficult to distinguish from the calcite, as they are almost identical in color, and many of the calcite veins are partly of pectolite -- in fact, every third or fourth vein will contain more or less of it.
-
There is, however, a very fine vein of pectolite about twenty-five feet further east from the natrolite bed; it runs from the floor to ceiling, and is about two inches in thickness; some specimens of which I took from these were unusually unique in both size and appearance.
-
Considerable quantities of pectolite may generally be found on the dump, but also in Shaft No. 1, and especially No. 2.
