Dolomite ( /ˈdɒləmaɪt/) is a carbonate mineral composed of calcium magnesium carbonate CaMg(CO₃)₂. The term is also used to describe the sedimentary carbonate rock dolostone.

Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone, or in old U.S. geologic literature as magnesian limestone. Dolomite was first described in 1791 as a rock by the French naturalist and geologist, Déodat Gratet de Dolomieu (1750–1801) from exposures in what are now known as the Dolomite Alps of northern Italy.

Dolomite is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.

Scott Henderson (born August 26, 1954) is a jazz fusion and blues guitarist best known for his work with the band Tribal Tech.

Born in West Palm Beach, Florida, Henderson began playing guitar at an early age. His formative musical years were spent listening to rock, blues, funk and soul, while his interest in jazz developed later on, thanks to the music of John Coltrane, Miles Davis and others. He still professes to being a blues player at heart.

After graduating from Florida Atlantic University, Henderson moved to Los Angeles and began his career in earnest, playing and recording with violinist Jean-Luc Ponty, bassist Jeff Berlin and "Players", and Weather Report's Joe Zawinul. Henderson first began receiving serious attention as the original guitarist for the Chick Corea Elektric Band. But he stayed only six months with Corea and left after some major clash.

Henderson formed Tribal Tech with bass player Gary Willis in 1984. Under the direction of Henderson and Willis, Tribal Tech became one of the most highly-regarded fusion bands of the 1990s. He toured and recorded with the band up until their dissolution following the 2000 album Rocket Science, and during that time brought himself to the forefront of modern jazz/fusion guitar playing. In 1991 he was named '#1 Jazz Guitarist' by Guitar World magazine, and in January 1992 he was voted best jazz guitarist in Guitar Player magazine's Annual Reader's Poll.
