Granite Fact Sheet

Granite is an igneous rock that forms when magma cools slowly beneath the earth’s surface, forming large, easily visible crystals of quartz, feldspar, and mica. Scientifically, an intrusive (plutonic) igneous...

Granite Life Cycle Inventory

After the face of the granite is exposed, the stone is removed from the quarry in benches, usually 8 to 12 feet square extending 20 feet or more using a...

Green Building Case Study

Natural stone has many innate attributes that make it a green building product: it is natural, low-maintenance, and exceptionally durable. It is worth considering how these and other properties of...

Guidance for Conformance to ANSI/NSC 373

This document complements American National Standard, NSF/ ANSI 373 – Sustainability Assessment for Natural Dimension Stone, by providing information, tips, sample forms, and other useful guidance on certifying to the...

Limestone Fact Sheet

Limestone is a sedimentary rock composed of calcium carbonate, plus calcium and/or magnesium. It is formed when layers of minerals (particularly calcite), fine sediment, and the skeletons and shells of...

Read More...

Limestone Life Cycle Inventory

The first step in quarrying is to gain access to the limestone deposit. This is achieved by removing the layer of earth, vegetation, and rock unsuitable for product—collectively referred to...

Read More...

Marble Fact Sheet

Marble is a metamorphic stone formed when limestone is subjected to intense heat, pressure and chemical solutions, causing the stone to reform into an interlocking structure of calcite, aragonite, and...

Quarry Site Best Practices

To address the potential stresses posed on the environment by the extraction of stone, read these operational suggestions which encourage environmentally responsible quarry practices. Proper site maintenance can reduce costs...

Reclaimed Stone Case Study

Disassembly and reuse of stone products can prove advantageous on both economic and environmental fronts. With regard to the former, several studies show that deconstruction of buildings is more cost-effective...

Sandstone Fact Sheet

Sandstone is a sedimentary rock formed when layers of eroded sediment are compressed and cemented with minerals through lithification. The stone is composed mainly of sand-sized grains, or clasts, of...

Sandstone Life Cycle Inventory

Processing operations include much more variation than extraction. Nevertheless, the general procedures begin with initial cutting, followed by application of a finish, and conclude with a second cutting or shaping...

Slate Fact Sheet

Slate is a metamorphic deposit that evolves from sedimentary rock consisting of clay or volcanic ash. While typically composed of numerous minerals, the predominant constituents include quartz and muscovite or...

Read More...

Slate Life Cycle Inventory

The slate quarrying process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and...

Solid Waste Management Best Practices

It is estimated that 175 million tons of quarrying waste are produced each year,¹ and although a portion of this waste may be utilized on-site, such as for excavation pit...

SRI & Heat Island Case Study

The metric associated with the heat island concept is known as Solar Reflectance Index (SRI). Defined by the Cool Roof Rating Council (CRRC)b, SRI is calculated as “the ratio of...

Stone Flooring Case Study

Relatively high material and installation costs for stone flooring may deter some designers from further considering the material. However, because of its enduring useful life and little need for extensive...

Transportation Best Practices

Continuous improvement of a transportation system requires frequent assessment of current operations. Both the shipper’s practices as well as the carriers’ performance should be evaluated, and feedback should be collected...

Water Consumption, Treatment, & Reuse Best Practices

Multiple quarry and fabrication processes implement water, often in continuous streams. In fact, it is a part of almost every step in the extraction, cutting, and finishing of dimensional stone...
