It was found that with increasing calcination temperatures, a veatchite phase was observed.
The broad peaks were indexed to strontium borate (PDF: 01-074-2316) and veatchite (PDF: 01-074-2316).
By increasing the calcination temperature from 710degC to 800degC, the intensities of the veatchite peaks increased.
* By the increase of calcination temperature from 400 to 710degC, new stable phases (veatchite and strontium borate) were observed.
Veatchite also occurs at the Billie mine (a species not previously confirmed in the Death Valley area).

Switzer was involved in the description and naming of five new mineral species during his career: veatchite
(1950), ordonezite (1955), paradamite (1956), paratellurite (1960) and galeite (1963).
