Very similar tubestone-microbialite associations occur in two isolated dolostone outcrops in the southern Paraguay Fold Belt.

Constancy of the microbialite fabric suggests a constant paleoenvironmental condition;

The tubestone fillings do not support the idea that the tubes were open spaces.

The association suggests a Marinoan cap carbonate to the southern Paraguay Fold Belt.
