The GSN Winnemucca Chapter will be hosting a virtual meeting on Wednesday, January 12th at 6:30 pm. The speaker will be UNR graduate student Dalton McCaffery and the talk is titled:

“Rare Metal Granitic Pegmatites: A Review with Examples from Nevada and California”

 Dalton’s abstract is below and the Zoom login details will be distributed prior to the meeting in a separate email to GSN members.

ABSTRACT:

“Rare Metal Granitic Pegmatites: A Review with Examples from Nevada and California”

Granitic pegmatites have the unique ability amongst other geologic systems to concentrate rare and critical metals such as Li, Be, Cs, Ta, and REE, many of which are vital to modern technology into mineable deposits. However, even with a significant amount of research available on these systems, these systems remain poorly understood. There are two primary competing hypotheses for rare metal pegmatite petrogenesis: (1) extensive fractional crystallization of a large (pluton-scale) volume of magma and (2) low-degree direct anatexis involving a large volume of source rock. This talk will briefly overview granitic pegmatite petrogenesis, and use examples from both Nevada (i.e., the Virgin Mountains Pegmatite Field, Clark Co.) and California (i.e., the Pala Pegmatite Group, San Diego Co.) to demonstrate that either type of petrogenesis may be possible.
