Crushed and dimension stones, which include 33 lithological varieties among igneous rocks, metamorphic rocks and sedimentary rocks, are mainly located in the southern and south-western part of Poland. Demand for this group of minerals is continuously high, which results from conducted and planned infrastructural investments. Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.The Complete Guide to Crushed Stone and Gravel Gra-Rock
