2025-26
Ge 112. Sedimentology and Stratigraphy.
12 units (3-5-4); third term, 2025-26.
Prerequisites: Ge 11 ab.
Systematic analysis of transport and deposition in sedimentary environments and the resulting composition, texture, and structure of both clastic and chemical sedimentary rocks. The nature and genesis of sequence architecture of sedimentary basins and cyclic aspects of sedimentary accumulation will be introduced. Covers the formal and practical principles of definition of stratigraphic units, correlation, and the construction of a geologic timescale. Field trip and laboratory exercises.
Given in alternate years; offered 2025-26.
Instructor: Grotzinger
Instructor: Grotzinger
Ge 121 abc. Advanced Field Geology.
12 units (0-9-3); first, second, third terms, 2025-26.
Prerequisites: Ge 120 or equivalent, or instructor's permission. For Ge 121a (Lamb): Ge 125 or instructor approval.
Field mapping and supporting laboratory studies in topical problems related to the geology of the southwestern United States. Course provides a breadth of experience in igneous, metamorphic, or sedimentary rocks or geomorphology. Multiple terms of 121 may be taken more than once for credit if taught by different instructors.
