About the Role
What General Information Do I Need to Know About This Position? This is a term appointment not to exceed 13-months with possible extensions up to a total of 4 yrs without further competition. Appointment to this position will not convey permanent status in the Federal service. Salary: First time hires to the Federal Government are typically hired at Step 01. GS-12: $101,206 (Step 01) to $131,571 (Step 10).
What You'll Do
- →Postdoctoral Research Fellowship Opportunity: Characterizing mineral resources, development of mineral system mappable criteria, and regional framework geology of mineral deposit in Southwest Alaska.
- →Introduction: The Kuskokwim mountains region of southwest Alaska hosts one of the world's largest gold deposits (Donlin Creek), past producers (e.g.
- →Nixon Fork) and numerous current exploration projects (e.g.
- →Flat, Illinois Creek-Waterpump Creek, Donlin, etc.).
- →These deposits are focused on critical minerals as principal commodities or contain known critical minerals as by- and co-products.
- →Deposits are hosted in varied geologic terranes, which include predominantly the Farewell, Angayuchum, and Ruby terranes, and vary in age from potentially middle Cretaceous to the Paleocene.
- →Deposits have a spatial, if not genetic, association with plutons of varying characteristics, which cluster from ca. 72-60 Ma.
- →What remains uncertain is the role basement and/or regional framework geology such as the timing of deformation and faulting, play in contributing to the development of the region's mineral resources.
- →Background: Critical mineral enrichments occur in association with a wide variety of mineral systems and tectonic environments.
- →Recent work has shown that precursor (i.e., Paleozoic) tectonic and magmatic events and crustal structure influenced the enrichment of critical minerals as by-products in Mesozoic mineral systems in Alaska (e.g., Kreiner et al., 2019).
- →Many different styles of mineral systems are known or suspected to occur throughout the state, resulting from the diversity of geologic terranes and tectonic environments in which they originally formed, tectonic processes during accretion, and syn- and post-accretionary processes.
- →Much of southwestern Alaska is composed of magmatic arcs, accretionary complexes, and continental fragments.
- →Boundaries between these features are obscured by overlap successions of Cretaceous basin stratigraphy.
- →The heritage and deep crustal architecture of most terranes are difficult to ascertain due to incomplete exposure and a lack of systematic investigation using modern analytical techniques.
