| 1. | The Oosterhout Formation mainly consists of sand, often containing glauconite.
|
| 2. | Thus references to " greensand marl " sometimes refer specifically to glauconite.
|
| 3. | The main potassium bearing minerals are glauconite and muscovite.
|
| 4. | Also, pellets composed of either glauconite or phosphorite are common in marine sedimentary rocks.
|
| 5. | Glauconite gravel is used for road surfacing.
|
| 6. | A green iron potassium silicate called glauconite in the Curtis indicates it was deposited in a shallow sea.
|
| 7. | The presence of glauconite and marine fossils in the uppermost sandstones indicate deposition in a shallow marine environment.
|
| 8. | Typically the shales do not contain many fossils, the coarser sandstones often have fractions of micas and glauconite.
|
| 9. | It is one of two minerals, along with glauconite, used in making the pigment known as green earth.
|
| 10. | The glauconite " per se " will incorporate electrochemically bound water ( CBW ) because of the clay types.
