Jeff L Doebrich
Jeff Doebrich is a Regional Science Advisor with the Office of International Programs where he is responsible for facilitating USGS cooperative science in Africa and the Middle East.
Jeff Doebrich has been an economic geologist with the USGS since 1982. His research has focused on a variety of mineral resource issues in the Great Basin of the western United States, in Central Asia, and in the Middle East.
In the 1980’s and 1990’s Jeff served two tours of duty with the USGS Saudi Arabian Mission, including one as Mission Chief Scientist. Jeff has coordinated large regional mineral resource assessments in the Great Basin and Central Asia, including the USGS mineral resource assessment of Afghanistan from 2004 to 2006. In 2010, Jeff led the overall USGS program in Iraq, a multidisciplinary effort involving mineral and water resource studies, establishment of an agrometeorological network, and creation of a national spatial data infrastructure.
From 2006 to 2016, Jeff was the Associate Program Coordinator for the USGS Mineral Resources Program. Since January 2017, Jeff has been the Africa and Middle East Science Advisor for the USGS Office of International Programs.

U.S. Geological Survey Mineral Resources Program—Mineral resource science supporting informed decisionmaking
The USGS Mineral Resources Program (MRP) delivers unbiased science and information to increase understanding of mineral resource potential, production, and consumption, and how mineral resources interact with the environment. The MRP is the Federal Government’s sole source for this mineral resource science and information. Program goals are to (1) increase understanding of mineral resource formati

Zinc-The key to preventing corrosion
Centuries before it was identified as an element, zinc was used to make brass (an alloy of zinc and copper) and for medicinal purposes. Metallic zinc and zinc oxide were produced in India sometime between the 11th and 14th centuries and in China in the 17th century, although the discovery of pure metallic zinc is credited to the German chemist Andreas Marggraf, who isolated the element in 1746.

Chromium-Makes stainless steel stainless
Chromium, a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point, is a silvery white, hard, and bright metal plating on steel and other material. Commonly known as chrome, it is one of the most important and indispensable industrial metals because of its hardness and resistance to corrosion. But it is used for more than the production of stainless steel and nonfe

Copper: a metal for the ages
Copper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. The discovery that copper alloyed with tin produces bronze marked the b

Geology and Nonfuel Mineral Deposits of Africa and the Middle East
A nation's endowment of nonfuel mineral resources, relative to the world's endowment, is a fundamental consideration in decisions related to a nation's economic and environmental well being and security. Knowledge of the worldwide abundance, distribution, and general geologic setting of mineral commodities provides a framework within which a nation can make decisions about economic development of

Gold deposits and occurrences of the Greater Caucasus, Georgia Republic: Their genesis and prospecting criteria
The south-central part of the Greater Caucasus region, Georgia Republic, represents an extremely prospective region for significant orogenic gold deposits. Gold-bearing quartz veins are concentrated in two extensive WNW-trending belts, the Mestia-Racha and Svaneti districts, within the northern margin of the Southern Slope Zone of the Great Caucasus orogen. This metalliferous region is dominated b

Geology and metallogeny of the Ar Rayn terrane, eastern Arabian shield: Evolution of a Neoproterozoic continental-margin arc during assembly of Gondwana within the East African orogen
The Neoproterozoic Ar Rayn terrane is exposed along the eastern margin of the Arabian shield. The terrane is bounded on the west by the Ad Dawadimi terrane across the Al Amar fault zone (AAF), and is nonconformably overlain on the east by Phanerozoic sedimentary rocks. The terrane is composed of a magmatic arc complex and syn- to post-orogenic intrusions. The layered rocks of the arc, the Al Amar

Ad Duwayhi, Saudi Arabia: Geology and geochronology of a neoproterozoic intrusion-related gold system in the Arabian shield
The Ad Duwayhi gold deposit, located in the east-central part of the Arabian shield, is the newest gold discovery in Saudi Arabia. Exploration to date has identified a gold resource of greater than 1 million ounces (oz) with significant potential for expansion. Gold mineralization was closely associated, in time and space, with emplacement of a late- to postorogenic, intracrustal, northwest-orient
