Fault (geology)

In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock mass movement. Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes.

A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is the intersection of a fault plane with the ground surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault.

Since faults do not usually consist of a single, clean fracture, geologists use the term fault zone when referring to the zone of complex deformation associated with the fault plane.

The two sides of a non-vertical fault are known as the hanging wall and footwall. By definition, the hanging wall occurs above the fault plane and the footwall occurs below the fault. This terminology comes from mining: when working a tabular ore body, the miner stood with the footwall under his feet and with the hanging wall hanging above him.

Viridian

Viridian is a blue-green pigment, a hydrated chromium(III) oxide, of medium saturation and relatively dark in value. It is composed more of green than blue. Specifically, it is a dark shade of spring green, the color between green and cyan on the color wheel, or, in paint, a tertiary blue–green color. Viridian takes its name from the Latin viridis, meaning "green".

The first recorded use of viridian as a color name in English was in the 1860s (exact year uncertain).

Variations of viridian

Paolo Veronese green

Paolo Veronese green is the color that is called Verde Verones in the Guía de coloraciones (Guide to colorations) by Rosa Gallego and Juan Carlos Sanz, a color dictionary published in 2005 that is widely popular in the Hispanophone realm.

Paolo Veronese green was a color formulated and used by the noted 16th-century Venetian artist Paolo Veronese.

Paolo Veronese green began to be used as a color name in English sometime in the 1800s (exact year uncertain).

Another name for this color is transparent oxide of chromium.

Viridian (album)

Viridian is a 2007 studio album by the Austin, Texas bluegrass band The Greencards. Their third Dualtone Records studio album, it was released on March 6, 2007.

Recording

In 2007, The Greencards were joined by Matt Wingate, a guitarist from Alabama, for their work on Viridian. On their previous albums, The Greencards had individually recorded their separate musical tracks in isolation booths of recording studios, but for Viridian, recorded their album together in real time in an open room, which was said to be a factor in a spontaneous feel for some of the album.

Most of the songs on Viridian are sung by Young, and all of the tracks on Viridian were written by The Greencards, with the exception of "Travel On", which was penned by Kim Richey of Nashville. Their sound, through Viridian, was likened to the Canadian alternative country band The Duhks.

Influences

The recordings on Viridian, in particular the songs "River of Sand", "Waiting on the Night" and "When I Was in Love With You", were said to evoke the sounds of progressive folk rock that emerged in the 1960s. The progressive nature of The Greencards' bluegrass sound has been compared to Nickel Creek and Alison Krauss & Union Station's own musical work to expand bluegrass.
