Abstract/Notes | Doré metasediments in the Arliss Lake area of the Michipicoten greenstone belt predominantly represent submarine-fan sedimentation in mid- to outer-fan settings; subaerial deposition was rare, occurring in a sandy braided stream environment and as mud-poor debris flows in a probable fan-delta setting. The Arliss Lake subbasin was likely small, and of an irregular configuration which restricted down-fan sediment distribution, promoting aggradational lobe development; it existed on a convergent plate margin. Felsic pyroclastic volcanism was periodically synchronous with epiclastic sedimentation but only rarely dominated. Paleogeographic development, addressed by comparing juxtaposed thrust-fault-bounded lithological packages of similar facing, suggests that the subbasin experienced several episodes of instability, which caused dramatic changes in relative sea level. |
