On the Formation of Coral Sand [PDF]
Nature, 1876 IN the best books on geology one finds that the formation of coral sand is attributed to trituration by the force of the surf, the waste of shells and minute globigerinae, and even to the droppings of those fishes which are said to browse upon the living coral.

Metagenomic views of microbial communities in sand sediments associated with coral reefs [PDF]
Microbial Ecology, 2021 Abstract Reef sediments, the home for microbes with high abundances, provide an important source of carbonates and nutrients for the growth and maintenance of coral reefs. However, there is a lack of systematic research on the composition of microbial community in sediments of different coral reef sites and the effect of microbial functional ...
