Laurence L. Sloss (August 26, 1913 – November 2, 1996) was an American geologist.^[1] He taught geology at Northwestern University from 1947 until his retirement in 1981.^[1]^[2]

He was president, Geological Society of America (GSA), with his tenure beginning in 1980.^[3] The GSA's Laurence L. Sloss Award is named in his honor.^[4] He was also president of the Society for Sedimentary Geology and American Geosciences Institute.^[5]

Education and field work

Sloss received his bachelor's degree at Stanford University and his Ph.D. at the University of Chicago in 1937.^[1]

He is known as a pioneer in the discipline of sequence stratigraphy,^[5] and for his descriptions of cratonic sequences or "Sloss sequences" in ancient North America. As a whole, these sequences are large-scale cycles in sedimentary rock records that indicate broad patterns of environmental change over geologic time – specifically marine transgression and regression.^[6]^[7]^[8]

Awards and recognition

He was awarded the William H. Twenhofel Medal from the American Association of Petroleum Geologists in 1980^[9] and the Geological Society of America's Penrose Medal in 1986.^[10]
