Thomas Seward Lovering

Thomas "Tom" Seward Lovering (May 12, 1896, St. Paul, Minnesota – April 9, 1991, Santa Barbara, California) was an American geologist, known for his innovative field and laboratory research on relations between mineable ore deposits and hydrothermal alteration of wall rock.

Biography Lovering was born on April 9th, 1896 in St. Paul, Minnesota.

During World War I, Lovering volunteered for the U.S. Navy and was trained as a naval aviator, but the war ended before he was assigned to combat duty. In 1919, he matriculated at the University of Minnesota School of Mines, where he graduated in 1922 with an E.M. (engineer of mines) degree. He then became a graduate student in geology at the University of Minnesota. There, he graduated in 1923 with an M.S. in geology and in 1924 with a Ph.D. in economic geology. At the University of Minnesota, he learned from his professors Frank F. Grout and John W. Gruner about the hydrothermal processes that form ores.

For the academic year 1924–1925, Lovering was an instructor in the University of Arizona's department of geology.

In 1925, he joined the U.S. Geological Survey (USGS) to do research, under the supervision of Bert Sylvenus Butler (1877–1960), on mining districts in Colorado's Front Range. In 1934, Lovering resigned from the USGS and became an associate professor in the University of Michigan's department of geology and mineralogy. From 1934 to 1942 he performed extensive laboratory investigations as a professor and during the summers he worked in Colorado for the USGS by investigating mining districts and participating in regional mapping projects in geology.

In 1942, Lovering took a leave of absence from the University of Michigan to rejoin the USGS full-time for war service during World War II. He worked in the USGS's Strategic Minerals Program and produced several reports on ore bodies in Colorado.

After World War II ended, he resumed his professorship at the University of Michigan for the academic year, but resigned in 1947 to accept a permanent position in the USGS's Mineral Deposits Branch. He continued this employment until 1966 when he retired at age 70. In 1976 he moved from Lakewood, Colorado to Santa Barbara, California, where he became a research associate at the University of California, Santa Barbara. In 1965 the Society of Economic Geologists (SEG) awarded him the Penrose Gold Medal.
