A biofilm and organomineralisation model for the growth and limiting size of ooids

Batchelor, Murray; Burne, Robert; Henry, B I; Li, Fei; Paul, Josef

Description

Ooids are typically spherical sediment grains characterised by concentric layers encapsulating a core. There is no universally accepted explanation for ooid genesis, though factors such as agitation, abiotic and/or microbial mineralisation and size limitation have been variously invoked. Here we examine the possible influence of microbial organomineralisation on the formation of some naturally occurring ooids. We develop a mathematical model for ooid growth, inspired by work on avascular brain...[Show more]
