Important Update News

The RRUFF Project has been migrated to RRUFF.net. Please update your bookmarks immediately, if you have not done so.

The data on this website is already three years out of date, and the entire website will be taken offline before the end of the year.

We are grateful to NASA for the funding of this effort.

The Mineral Evolution database is currently under development.

The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.

A	This mineral is Anthropogenic.
G	This mineral is directly dated.
B	This mineral is reported as having this age.
Y	This mineral is using an age reported as an element mineralization period.
O	This mineral is using an age calculated from all data at the locality.
R	The age displayed for this mineral originates from a different, non-child locality.
P	The age displayed for this mineral is the range of ages for this mineral at all of this locality's children.
	This mineral's age has not yet been recorded.

Locality Notes from all Ages at Locality:

Age ID	Locality Notes
Michelle_789	Birch Creek low-silica rhyolite lava. It is the first rhyolitic unit to erupt in the region. 150 m high exposures of flow banded, devitrified, tan lava in cliffs near Birch Creek Campground. Of the Rooster Comb Caldera.
Michelle_790	See Table 2. "Tuff of Leslie Gulch". Unit Type described as "Outflow Tuff", of the Rooster Comb Caldera. "The Tuff of Leslie Gulch is a sparsely porphyritic, weakly peralkaline, alkali rhyolite containing phenocrysts of sodic sanidine and sparse quartz and oxidized mafic phases."
Michelle_796	See Table 2. "Three Fingers Rock rhyolite dome", it is also referred to as a rhyolite plug
Michelle_797	See Table 2. "Perlitic intrusion exposed in Leslie Gulch".
Michelle_801	The Sucker Creek Formation consists mainly of lacustrine volcaniclastic rocks and tuff, deposited in a moist temperate lowland climate. Strata are exposed locally along Succor Creek and are among the oldest strata deposited in the Owyhee River region.

"Our new 40Ar/39Ar age of 16.8 ± 1.1 Ma on plagioclase from the Birch Creek low-silica rhyolite lava (sample TB-278A in Table 2) is of such low precision that it does not establish conclusively that this unit is older than the 15.81 Ma Tuff of Leslie Gulch."
