Luck Stone's Goose Creek Quarry

From www.luckstone.com:

This plant was acquired by Luck Stone in 1993 and is located just south of Route 7 near the City of Leesburg. Goose Creek plays an important role by serving the needs of area customers and complimenting our nearby Leesburg plant. Goose Creek has won the National Stone, Sand & Gravel Association’s Showplace Award.

Goose Creek mines a type of rock known as traprock by miners or diabase by geologists – a dense, igneous rock with a greenish-black to bluish-black color. Formed by hot magma 200 million years ago, diabase is composed mainly of pyroxene, a dark mineral containing iron, and plagioclase, a lighter mineral in weight and color. Other minerals lending it its green-black color are epidote (green) and hornblende (black).
