DONGWAN upper part of microbialite

This page authored by Steve Kershaw


Photos showing eroded digitate microbialite near top of microbialite unit. The two slab samples show eroded dome overlain by gastropod-rich packstone and grainstone.


Upper two thin section photos show recrystallised microbialite and shelly debris. Bottom photo shows detail of eroded surface of microbialite dome, with mineralised surface. It is possible that this is a dissolution feature. Thin section photos are 1.5 mm wide


See discussion in Kershaw et al. (2012) Geobiology 10, 25-47.
