Peloidsとは 意味・読み方・使い方

Peloids are fecal pellets that are produced by organisms that consume calcium carbonate mud. They are formed from organism excretions of undigested calcium carbonate mud. Peloids tend to be oval in shape and uniform in size. They are smaller than ooids and tend to be no larger than a silt to fine-sand size. Unlike ooids, peloids lack concentric and radial internal structures, making them easy to distinguish from ooids and other non-skeletal grains. Instead of being identified by an internal structure, like ooids, peloids can be identified by their dark color due to the organic matter from which they are formed.
