Summary
[edit]DescriptionPrecious opal collecting site (Spencer, Idaho, USA) 2.jpg |
English: This precious opal pay site in the town of Spencer is located on the eastern side of Interstate 15, eastern Idaho. Rocks are quarried at a nearby mountain and dumped here. The material is composed of Early Pliocene rhyolitic volcanics that were erupted from the Heise Volcanic Center. Observed lithologies range from rhyolite to rhyolitic obsidian to hydrothermally altered versions. The obsidian varies: black spherulitic obsidian, brown spherulitic obsidian, flow-banded spherulitic obsidian. Opal (= SiO2·nH2O - hydrous silica) occurs in these rocks - it is secondary (early secondary?) and hydrothermal in origin. The opal fills cavities and lithophysae in the host rocks. Observed opal varieties here include common opal (milky opal; = opalite, which is opal rock), hyalite opal, and precious opal. Also noted were turgite on hyalite and drusy quartz.
Stratigraphy: possibly derived from a lava flow called the Opal Mountain Rhyolite, Kilgore Tuff, upper Heise Group, Lower Pliocene, 4.45 Ma Locality: derived from an opal mine on the southern side of Opal Mountain between Rattlesnake Creek & Three Mile Creek, ENE of Spencer, north-central Clark County, north of the eastern Snake River Plain, Idaho, USA (44° 22’ 43.94” North latitude, 112° 05’ 38.13” West longitude) |
