Biography
Doug Kreiner is a research geologist at the USGS Alaska Science Center in Anchorage, Alaska. Doug joined the USGS in late 2016 following 5 and a half years in the mineral exploration industry. His research involves field-based studies of fluid-rock interactions in the upper crust and the time-space genesis of mineral deposits with a particular interest in the links between regional scale tectonic processes and metallogenesis of Cu and Au dominant systems. Current projects focus on the metallogenic evolution of eastern interior Alaska, characterization, documentation and geochronology of porphyry deposits across Alaska, developing a mineral systems framework for Alaska, and attempting to understand where, how, and why critical mineral enrichments occur in Alaska mineral systems. Kreiner earned a BS in Geosciences and Environmental Studies at Northland College (2004), his M.S. from Colorado State University (2006) and his PhD from University of Arizona (2011).

Status: Active Alaska Earth Mapping Resources Initiative (Earth MRI)
Our objective is to provide a strategic framework for planning, coordination, and execution of the USGS Earth Mapping Resources Initiative (Earth MRI) in Alaska. Earth MRI aims to improve knowledge of the U.S. geologic framework through new geological and geophysical mapping and to identify areas that have the potential to contain undiscovered critical mineral resources.

Status: Active Tectonic and Metallogenic Evolution of the Yukon-Tanana Upland, Alaska
The Yukon-Tanana upland in eastern interior Alaska is a geologically complex block containing deposits of base-metal, platinum-group-element, and gold-silver-copper mineralization. It also hosts numerous mineral systems that are known or suspected to contain critical minerals.

Status: Active Petrology, Tectonic Setting, and Potential for Concentration of Rare Earth Elements (REE) and High Field Strength Elements (HFSE) in the High-K Darby and Kachauik Plutons, Seward Peninsula, Alaska
One of the geologic environments that host rare earth and other critical and strategic element deposits are alkaline intrusive rocks.

Evaluation of the analytical methods used to determine the elemental concentrations found in the stream geochemical dataset compiled for Alaska
A recent U.S. Geological Survey data compilation of stream-sediment geochemistry for Alaska contains decades of analyses collected under numerous Federal and State programs. The compiled data were determined by various analytical methods. Some samples were reanalyzed by a different analytical method than the original, resulting in some elements...

Systems-deposits-commodities-critical minerals table for the earth mapping resources initiative
To define and prioritize focus areas across the United States with resource potential for 35 critical minerals in a few years’ time, the U.S Geological Survey Earth Mapping Resources Initiative (Earth MRI) required an efficient approach to streamline workflow. A mineral systems approach based on current understanding of how ore deposits that...

Links between tectonics, magmatism, and mineralization in the formation of Late Cretaceous porphyry systems in the Yukon-Tanana upland, eastern Alaska, USA
Cretaceous-Paleocene porphyry Cu(±Mo±Au) occurrences are scattered throughout the Yukon-Tanana upland in eastern Alaska. Known occurrences in eastern Alaska are poorly characterized, despite a resurgence in exploration. Porphyry deposits in the upland are emplaced into structurally complex metamorphic rocks representing a variety of tectonic...
