from The Century Dictionary and Cyclopedia
- n. A grass-green cleavable calcite from India which derives its color from inclosed glauconite.
An opaque calcite of a grass-green colour, occurring as large cleavage masses in central India and known as hislopite, owes its colour to enclosed "green-earth" (glauconite and celadonite).
The case of hislopite, which encloses up to 20\% of "green earth," has been noted above.
