| 説明 | (cut & polished surface)-------------------------------------"Jasper" is a rockhound term for various types of colorful and/or interestingly-patterned, siliceous rocks. This rock slice is lapidary-grade material that may be one of the many named "jaspers" out there. If anyone recognizes this, in terms of name and/or locality, please leave a comment.The rock has been intensely fractured and brecciated (click on the photo once or twice to zoom in). Such breccias are often formed in fault zones (tectonic breccias). |
