Bj. Willis et Ak. Behrensmeyer, ARCHITECTURE OF MIOCENE OVERBANK DEPOSITS IN NORTHERN PAKISTAN - REPLY, Journal of sedimentary research. Section B, Stratigraphy and global studies, 65(3), 1996, pp. 403-407
Our study of overbank deposits in the Chinji Formation of northern Pak
istan focused on documenting facies architecture and testing models of
overbank deposition and floodplain construction. Studies that provide
detailed cross-sectional maps of channel body architecture in fluvial
successions are becoming increasingly common, but very few studies of
this kind span overbank deposits for significant distances. Time in a
lluvium is recorded mainly in overbank deposits, and processes of floo
dplain construction may control the types of overbank deposits preserv
ed, the stacking of channel bodies, and the distribution of fossil rem
ains. Bridge (1995) questioned two major aspects of our study: (1) whe
ther our bedding diagrams were constructed properly and (2) whether th
e data presented are adequate to test our five hypotheses of overbank
construction. We address each of these points in turn below.
