Environmental indicator of the Early Ordovician (and other Phanerozoic periods) by buildup of siliceous sponge-microbe reef mounds. The article talks about the common attributes of the reef mounds which include the abundance of thrombolites, but fewer stromatolites during the Phanerozoic episodes of reef mound construction. I will mostly refer to the Ordovician microbialites mentioned in this article

Descriptions of algal stromatolites found in the Shakopee Formation (in particular the Willow River Dolomite member) of the Lower Ordovician of the Upper Mississippi Valley are found to have been deposited in an environment similar to that of modern intertidal carbonate depositional environments of Florida and Australia. Similar depositional environments in which the Willow River dolomite was formed is found in the Appalachian, Ozark, and central Texas areas during the Lower Ordovician.

Siliciclastic domal stromatolites found in the Later Ordovician Eureka Quartzite of Southern Nevada and Eastern California give some insight into the growth of microbialites in siliciclastic environments - I have blogged about this called Environment vs. Microbialites.

This authors of this article has come up with a method of classification of stromatolites based on their geometric shapes and how their shapes, sea-level, and the environment affect their growth.
