Limestone—A Crucial and Versatile Industrial Mineral
Limestone comes in many different varieties. Chalk is a very fine grained, porous marine limestone composed almost entirely of microscopic fossils. Travertine is a freshwater sedimentary limestone that has very thin, crenu-lated layers and is commonly formed at springs.

Introduction: Impacts of Quarrying A quarry is an area from which resources such as marble, limestone, sand and granite are extracted for industrial use. Once depleted of their desired resources, quarries are frequently abandoned. The majority of quarries are located fairly close to urban environments due to the expense of transportingDust is one of the most visible impacts associated with limestone quarrying due to the drilling, crushing and screening of the rock. The mine site conditions can affect the impact of dust generated during extraction, including rock properties, moisture, ambient air currents and prevailing winds, and the proximity to population centers.Environmental Hazards of Limestone Mining Sciencing

A quarry is a place where rocks, sand, or minerals are extracted from the surface of Earth.A quarry is a type of mine called an open-pit mine, because it is open to Earth's surface.Another type of mine, a subsurface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials. The quarries in Malaysia are utilizing different types of rocks for quarrying, of which granite and limestone are a few of the important ones that are commonly available. Mining and quarrying are important for obtaining useful natural resources. Important types of stone quarrying are the following: 1. Open-pit QuarryStone Quarry: The Complete Guide Hanson
