Sireuil Limestone

Sireuil Limestone is a medium-grained limestone quarried in Sireuil (Charente), approximately 12 km southwest of Angoulême, France. This natural stone is composed mainly of fossilized mollusks (bivalves), echinoderms (Micraster), and bryozoans, giving it a unique texture and character. Its mineral composition includes quartz, micas, glauconite, opal-cristobalite, and clay minerals such as smectite, illite, and kaolinite. Additionally, it contains heavy minerals like tourmaline, staurolite, and andalusite, enhancing its geological complexity.
Sireuil Limestone is prized for its durability, versatility, and historical significance, having been widely used in architecture, sculpture, and heritage restoration. Its workability and resistance to weathering make it a preferred choice for masonry, façades, and ornamental stonework, reflecting the timeless elegance of French limestone.
