Summary
[edit]DescriptionOpalite 4.jpg |
English: Opalite from an unrecorded locality (western USA?). (bedding plane view; 14.7 centimeters across at its widest)
Opalite is an opal-dominated rock (opal = amorphous hydrous silica = SiO2·nH2O). “Opal” is a mineral/mineraloid name. “Opalite” is a rock name. Opalites form principally by alteration of volcanic rock or alteration of siliceous sinter (a type of hot spring deposit). They are often described as “impure” opal rocks. They lack the famous “fire” & rainbow colors of gem-grade opal. |
