A new U-Ti-Ca-HREE hydrated oxide and associated niobian rutile from Topaz Valley, Utah

In October of 1988, specimens of yellow and/or white acicular needles growing out of equant to platy hematite were collected from the east side of Topaz Valley. For the past five years, attempts have been made by all of the authors to completely characterize what is believed to be a new mineral species. Because of several major factors the space group, exact formula, and structure are still unknown. The potentially new mineral and some associated minerals are described here with the hope that elsewhere in the world better and more material exists that will allow complete characterization. -from Authors
