GSS Lab Provides Fission Track, UPb, and Mineral Separation Services

GeoSep Services (GSS) is a locally owned small business, staffed by a small group of loyal employees. We are dedicated to providing high-quality mineral separations along with apatite and zircon fission track+UPb analyses to support the international geochronology/thermochronology community.

GSS is located in Moscow, Idaho, within the beautiful Palouse region of Idaho and Washington, USA.

We specialize in apatite fission track (AFT) analysis, zircon fission track (ZFT) analysis, zircon UPb, and mineral separations. Please note: as of April 2020, for an additional fee, we can provide pyrite (sulfide) removal/cleanup of zircon fractions (DIM sink) if requested.
