The human population is sparse Where the Cosumnes River has eroded Magma formed through the subduction of the ancient Farallon Plate rose in plumes ( plutons) deep underground, their combined mass forming what is called the Sierra Nevada batholith. There are still great variations even among areas that are of the same elevation, with "Giant Sequoia, the largest trees on Earth, [growing] in groves adjacent to barren patches where soil is absent and bedrock is exposed" (Hahm). This subduction is believed to have occurred at the end of the Cretaceous Period, between 115 and 87 Ma (Unger). Blewitt and colleague Bill Hammond, who run the University's Nevada Geodetic Laboratory, partnered with the University of Western Washington, the University of California, Berkeley and the University of Ottawa in the research. The Sierra Nevada Batholith exposed during this process consists of granodiorite and other similar coarse-grained crystalline rocks. This project will document the post-intrusive cooling and erosional history of this part of the batholith by applying a suite of thermochronometers to sample transects collected across 3-6 km thick tilted sections of batholithic rocks exposed beneath the Tertiary unconformity by Basin and Range normal faulting.
