| 1. | The identification of laumontite goes back to the early days of mineralogy.
|
| 2. | Laumontite easily dehydrates when stored in a low humidity environment.
|
| 3. | Prehnite pseudomorphs after laumontite ( epimorphs ) have been found in India.
|
| 4. | Minerals found in association with powellite include molybdenite, ferrimolybdite, stilbite, laumontite and apophyllite.
|
| 5. | The dehydrated laumontite is very friable, often falling into a powder at the slightest touch.
|
| 6. | Mineral assemblages include kaolinite and montmorillonite with laumontite, wairakite, prehnite, calcite and chlorite.
|
| 7. | The term " leonhardite " bears his name, being defined as a partially dehydrated, opaque laumontite.
|
| 8. | Excellent white bow ties of stilbite are found here on calcite and quartz, associated with heulandite and laumontite in cavities.
|
| 9. | The mineral laumontite, which Laumont discovered in the mines of Huelgoat, was named after him by Ren?Just Ha�y.
|
| 10. | The scolecite is commonly found alone or on stilbite and is covered with laumontite or colorless, pale green or white fluorapophyllite.
