Sequence boundaries (sea-level fall events) are redesignated following a numbering scheme suggested by Hardenbol et al. (1998) and Snedden and Liu (2010); however, the letters Tr, J, and K are prefixed to each designation for convenience to make the numbers unique and not to confuse them with similar numbers in other periods. (Three events in the Toarcian [JTo5–JTo7] are included provisionally, pending documentation of more wide- spread occurrence.)

Sedimentary Geology Division and Structural Geology and Tectonic Division Joint Award Stephen E. Laubach Structural Diagenesis Research Award Nominations due 1 Apr. The Stephen E. Laubach Structural Diagenesis Research Award Fund promotes research combining structural geology and dia- genesis and curriculum development in structural diagenesis. This award addresses the rapidly growing recognition that fracturing, cement precipitation and dissolution, evolving rock mechanical properties, and other structural diagenetic processes can govern recovery of resources and sequestration of material in deeply bur- ied, diagenetically altered and fractured sedimentary rocks. The award highlights the growing need to break down disciplinary boundaries between structural geology and sedimentary petrol- ogy, exemplified by the work of Dr. Stephen Laubach and col- leagues. The award alternates between being awarded by the Sedimentary Geology Division on odd numbered years, and the Structural Geology and Tectonics Division on even-numbered years, reflecting the focus of the award on this cycle. Graduate students, postgraduate, and faculty-level researchers are eligible. For information application requirements, go to community .geosociety.org/sedimentarygeologydiv/awards/laubach.
