Question: The Lincoln Memorial is constructed from which type of marble?
About the article "Lincoln Memorial", section "Statue".

Candidate passages:
Sylacauga marble has been praised by sculptors as equivalent to Italy's famous Carrara marble, and is noted for its translucency.
It was used for the bust of Abraham Lincoln which resides in the United States Capitol rotunda.
It was used for the ceilings in the Lincoln Memorial, and was also used in Washington Monument and for the interiors of the United States Supreme Court Building.
Aside from use as sculptural media and as a building stone, the marble is also used in industry as a coating to whiten high-quality paper, for electrical insulation, pigment, and other purposes.
It is used in agriculture as a soil amendment.
On 12 September 1969, Alabama's legislature passed Act 755, which made marble the state's official rock. 
On March 4, 1921, the United States Congress approved the burial of an unidentified American serviceman from World War I in the plaza of the new Memorial Amphitheater.
On November 11, 1921, the unknown soldier brought back from France was interred inside a three-level marble tomb.
The marble came from a Yule Marble Quarry located near Marble, Colorado.
The marble for the Lincoln Memorial and other famous monuments was quarried there.
The bottom two levels are six marble sections each and the top at least nine blocks with a rectangular opening in the center of each level through which the unknown remains were placed through the tomb and into the ground below.
A stone other than marble covers the rectangular opening. 
Selecting the marble for the exterior was a competitive process with five samples submitted to the Lincoln Memorial Commission for consideration; three from Georgia (Cherokee, Southern and Amicalola), one from Vermont (Dorset White) and Yule marble.
Of the samples, Memorial architect Henry Bacon wanted to use Yule marble in spite of its higher cost because the stones "whiteness and delicate veining" placed it "above any white building marble in appearance that I have seen here or abroad".
The Memorial commission voted to award the marble contract for Yule marble on 26 September 1913 but the matter was not settled.
Other bidders raised objections about Yule quality, ability to quarry the needed quantity and its durability.
Colonel W. W. Harts, the US Army Engineer Officer in charge of Public Grounds and overseer of the project, commissioned geologist George Perkins Merrill to make a determination.
After visiting the quarry, Merrill concluded Yule marble met the needed requirements.
Yet Secretary of War Lindsley Garrison called for testing by Bureau of Standards which gave a positive report on the use of Yule marble.
He also sent a 17 January 1914 letter to United States Commission of Fine Arts about the use of Yule marble and a reply was sent five days later that compared to the other marbles submitted for consideration Yule "fit pre-eminently for a structure of the character of the Lincoln Memorial".
The contract for Yule marble was awarded 14 March 1914 The contract was the most expensive and most demanding in the history of Yule marble at $1,080,000.
The marble came out of Quarry 3, with the first shipment leaving Marble on 25 May 1914 and the final on 16 June 1916.
The high standards resulted in a high rejection rate, yet the contract was completed 5 months ahead of schedule.
Only a small amount of the marble quarried ever reached the finishing mill.
The amount of rejection is based on summary statements given by the company president J.F.
Manning.
In June 1914 Manning estimated that a monthly quarrying of would yield to of acceptable marble.
In 1915, Manning stated sometimes less than 10% of the quarried marble was shipped to the Memorial site.
Once delivered to the mill site, marble blocks for other than the columns were taken to Shop 3 after being sawed into multiple pieces with a wire saw and the gang saws in one of the two mills.
The wire saw and 20 of the 30 gangs saws were cutting nothing but Memorial marble 24 hours a day in May 1914.
Marble for the 38 columns was offloaded in front of Shop 4.
Each column comprised 11 drums and the top piece, with each of the 418 marble drums taking more than 18 hours to fashion. 
The Colorado Yule marble (a.k.a.
Yule Colorado marble) comes from the Leadville Limestone of Mississippian age quarried near the mountain.
It was formed by contact metamorphism in the Tertiary period following the intrusion and uplift of nearby granitic Treasure Mountain dome.
Yule marble was used in the building of the Lincoln Memorial.
The Yule marble quarry is at an elevation of on the west side of Treasure Mountain along Yule Creek.
The quality and durability of the Yule marble was questioned prior to the building of the Lincoln Memorial as was the recently opened quarry's ability to provide the quantity and size required for construction. 
The tomb is in the center of a 12½ acre (51,000 m²) plot.
Constructed of Massachusetts granite, it has a rectangular base surmounted by a -high obelisk and a semicircular entrance way.
A bronze reproduction of sculptor Gutzon Borglum's head of Lincoln in the U.S. Capitol rests on a pedestal in front of the entrance way.
Four flights of balustraded stairs—two flanking the entrance at the front and two at the rear—lead to a level terrace.
The balustrade extends around the terrace to form a parapet.
Originally open to the public, the terrace has since been closed due to safety concerns.
In the center of the terrace, a large and ornate base supports the obelisk.
On the walls of the base are 37 hewn stones, cut to represent raised shields, each engraved with the name of a State at the time the tomb was built.
Each shield is connected to another by two raised bands, and thus the group forms an unbroken chain encircling the base.
Four bronze statues adorn the corners of the latter.
They represent the infantry, navy, artillery, and cavalry of the Civil War period.
In front of the obelisk and above the entrance stands a full-length statue of Lincoln.
The interior of the memorial, constructed of marble from Minnesota, Missouri, Massachusetts, Arkansas, Utah, Italy, Spain, France, and Belgium, contains a rotunda, a burial room, and connecting corridors.
A replica of the Daniel Chester French statue in the Lincoln Memorial, in Washington, D.C., dominates the entrance foyer.
The walls of the rotunda are decorated with 16 marble pilasters, which are separated by marble panels.
The pilasters symbolize Lincoln and the 15 Presidents who preceded him.
The room also contains 36 bronze panels, one for each State at the time of Lincoln's death.
The ceiling is of palladium leaf.
Corridors lead from the rotunda to the burial room at the rear of the memorial.
Located in niches along the corridor walls are eight statues by prominent sculptors depicting various phases of Lincoln's life.
Four bronze tablets on the walls are engraved with theFarewell Address, the Gettysburg Address, a portion of the second inaugural address, and a biographical sketch.
Large gold stars in sets of 12 at each corner of the memorial represent the 48 States in the Union at the time of its remodeling.
The burial room features black and white marble walls and a ceiling of gold leaf.
At its center stands the cenotaph, a 7-ton block of reddish marble inscribed with Lincoln's name and the years he lived.
It marks the approximate location of the burial vault, which is 30 inches behind and 10 feet below.
Nine flags are arranged in a semicircle around the cenotaph.
Seven of them—the State flags of Massachusetts, New Jersey, Pennsylvania, Virginia, Kentucky, Indiana, and Illinois—commemorate the homes of Lincoln and his ancestors.
The eighth and ninth are the Stars and Stripes and the Presidential flag.
The inscription "Now he belongs to the ages," reputedly spoken by Secretary of War Edwin M. Stanton at the time of Lincoln's death, is inscribed in the wall above the U.S.
Flag.
Along the south wall of the burial room are four crypts containing the remains of Mrs. Lincoln and three of Lincoln's four sons (his eldest, Robert Todd Lincoln, is buried at Arlington National Cemetery).
The tomb was built with additional crypts for members of Lincoln's family in addition to the four spaces already used.
However, as the remaining members of Lincoln's family decided not to be buried at the tomb, the other crypts remain empty.
