Limestone: areas of origin, materials and further reading.
Three localities identified by Reza Molai for exploring Iranian limestone.
A 2026 study examines limestone samples from different parts of Khorramabad, comparing mineralogy, porosity, strength and durability.
The samples differ in suitability for construction. The area name alone therefore does not define uniform performance. For a supply, test records should relate to the actual material and selected batch.
Limestone is a predominantly carbonate sedimentary rock. The USGS guide introduces its composition and uses.
