I do not have the necessary technical information about the Taconite Calcarenite of the United States. However, as a general guideline, calcarenite rocks tends to be porous and sensitive to weathering, and therefore they may not be recommended for long-term use in very sunny and harsh climates without proper maintenance and protection. It is always best to consult with a technical expert in the field before determining the suitability of a specific material for a particular application.
