Mineral Evolution Database

Created and maintained by the Mineral Evolution Project in partnership with RRUFF and mindat.

Mineral locality data provided by mindat.org

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.

Giersdorf_00000651	268	266	late- to post-Kazanian	Biostratigraphy	Age is interpreted by the author as being linked to the "Mid Permian Event" which is a surge of tectonic activity that represents the final act of the Hercyanian/Variscan cycle	Yes	24815	Trento Province (Trentino), Trentino-Alto Adige, Italy	Trento Region	Cassinis et al. (2008)	IJG127_519	Age of the Val Daone Conglomerate is expressed as Mid to Upper Permian, late to post Kazanian and possibly up into the lower Tatarian. The age is derived from palynological evidence as well as other paleontological sources compiled and given an estimated age. See fig. 11
Giersdorf_00000652	276	273	276-273	Biostratigraphy		Yes	24815	Trento Province (Trentino), Trentino-Alto Adige, Italy	Trento Region	Cassinis et al. (2008)	IJG127_519	Age of the Treviogo is described as lower to middle Permian, mostly Kungarian. The age is derived from palynological evidence as well as other paleontological sources compiled and given an estimated age. See fig. 11
Giersdorf_00000653	281	277	281-277	Biostratigraphy		Yes	24815	Trento Province (Trentino), Trentino-Alto Adige, Italy	Trento Region	Cassinis et al. (2008)	IJG127_519	Age of the Collio Formation is described as lower Permian, mostly Artinskian. The numbers do not agree with the GSA's Arinskian age as the paper uses a different Time Scale. The age is derived from palynological evidence as well as other paleontological sources compiled and given an estimated age. See fig. 11
Giersdorf_00000654	266	252	266-252	Biostratigraphy		Yes	24815	Trento Province (Trentino), Trentino-Alto Adige, Italy	Trento Region	Cassinis et al. (2008)	IJG127_519	Age of the Verrucano formation is described as Upper Permian and Upper Tatarian. The age is derived from palynological evidence as well as other paleontological sources compiled and given an estimated age. See fig. 11
