GROWTH STYLES OF SHELF-MARGIN CLINOFORMS: PREDICTION OF SAND- AND SEDIMENT-BUDGET PARTITIONING INTO AND ACROSS THE SHELF

摘要

Growth styles of shelf-margin clinoforms are reliable but understudied predictors of sand- and sediment-budget partitioning into and across the shelf. Three discrete clinoform-growth styles were recognized, including (1) strongly progradational shelf-margin clinoforms with low growth-trajectory angles (G(ct),), low aggradation to progradation ratios (A/P), low clinoform heights (H-c), and long clinoform length (L-c); (2) mixed progradational and aggradational shelf-margin clinoforms with moderate Gct, moderate A/P, intermediate H-c, and moderate L-c; and (3) strongly aggradational clinoforms with high G(ct), high A/P, high H-c, and short L-c.
