Deadman Creek Geology Trip-Caine
August 27, 2016
The Building of the Sangre de Cristos:
Evidence at Deadman Creek
Trip leaders: Jonathan Caine, Ph.D. USGS
The formation of the Sangre de Cristo Mountains is a complex tale that involves two distinct mountain building events. 70 to 50 million years ago compressional forces of the Laramide orogeny caused layers to buckle upward and slide past each other. More recently, from 19 million to the present, the direction of the force has reversed and extension has pulled apart the crust, forming the Rio Grande rift. The story of these mountain building forces are recorded in the rocks as faults. USGS geologist Jonathon Caine will lead a field trip into the Deadman Creek drainage basin where the faults are exposed to discuss how these faults tell the geologic history of the Sangres.
About the Trip Leader
Jonathan S. Caine, Ph.D. USGS Dr. Caine is a Research Geologist with the U.S. Geological Survey. His work is focused on characterization of fault zones, fracture networks, and fluid flow in the Earth’s upper crust. He combines structural geology, hydrogeology, and detailed field studies to characterize fault zone architecture and permeability structure; fault rock textures and deformation mechanisms; conduct direct fault rock dating; and fault and fracture network related fluid flow as it pertains to groundwater supply, mineral deposits, hydrocarbon migration, environmental geochemistry of hydrothermally altered and complexly deformed crystalline-rock aquifer systems, particularly in alpine watersheds. Caine also works closely with graduate students and colleagues at the University of Colorado, Boulder and the Colorado School of Mines. He received his B.A and M.A. in Geology from S.U.N.Y, New Paltz (1986 and 1991) and his Ph.D. in Geology from the University of Utah (1999) with concentration in Structural Geology and Hydrogeology. Caine's work has been conducted in the northeastern Appalachians, the Basin and Range, east Greenland, the southern Rocky Mountains, and the Rio Grande rift.
