Abutment

Agate
A variegated variety of quartz showing colored bands or other markings (clouded, mosslike, etc.).
Abrasive finish
A flat non-reflective surface finish for marble.
Acid
Igneous rock with more than 66% silica.
B
Baluster
A miniature pillar or column supporting a rail, used in balustrades.
Balustrade
An ornamental fencing consisting of a series of balusters supporting a handrail or molding.
Basic
Igneous rock containing silica between 45% and 52%.
Board
It is a fracture surface of a rock en noted that relative displacement.
Bond stone
Used in varying percentages to anchor or bond the stone veneer to the backing material. Bond stones are generally cut to twice the bed thickness of the material being used.
Bracket
Steel disc that holds and pulls the diamond wire, so it can operate in either direction.
C
Limestone
Sedimentary rock consisting mainly of carbonates. The two most important are calcite and dolomite.
Calcite
Mineral composed of calcium carbonate (CaCO3).
Chain saw
Cutting instrument with a device that travels on an auger, a cutting arm with about 3m long and fitted with a stream lined with diamond points.
Coating
Material formed by soil, sand, etc.. occurring on a deposit which is removed to open a quarry.
D
Defect
Those features which affect or have the potential of affecting the structural soundness of building stone, or may affect the durability of the building stone. Sometimes used for visual features such as xenoliths or veins.
Dolomite
Carbonate rock with a high percentage (90 to 100%) of dolomite.
E
Entasis
Curve of the upper two thirds of a column.
F
Face
This refers to the exposed portion of stone. The word "face" can also be used when referring to the edge treatment on various cutting stock materials.
Fail
Fractured rock with vertical and horizontal.
Field
Natural accumulation of a particular type of rock from possible exploitation.
G
Gap
Sedimentary rock composed of angular fragments, meaning a minimum of material transport
Granular
The texture of a rock with grain size almost equal.
Grain
The easiest cleavage direction in a stone. "With the grain" same as "natural bed". Also, particles (crystals, sand grains, etc.) of a rock.
I
Igneous
One of the three great classes of rock (igneous, sedimentary and metamorphic), solidified from molten slate, as granite and lavas.
J
M
Mafic
Term referring to the ferromagnesian minerals and rocks of these minerals.
Marble
Metaformizado limestone, formed by recrystallization of carbonate rock. Commercially the group of marble stones include those capable of winning polish such as limestone, travertine and serpentinites.

N
Neutral
Igneous rock containing more than 52% and less silica.
P
Pulley blocks
Cutting machine, comprising a horizontal diamond disk and a vertical series of diamond disks.
Schistose
Rock that has minerals under an arrangement in parallel layers.
Sedimentary rock
Rocks formed by the accumulation of sediment in the water or air.
Sedimentation
Deposition of material with organic or inorganic.
Sepentinito
Metamorphic rock composed almost entirely of serpentine and relics of primary minerals.
Slit
Defect or crack in rock.
Squaring blocks
Operation by which the stone blocks are disassembled taken to acquire a regular and standard dimensions.
Stratification
Provision of a rock in general sedimentary layers or strata thickness and varied characteristics.
Texture
Arrangement, distribution and mutual relations between the components of a rock, for example grain size, rounding of clasts, the texture of igneous rocks.
Vein
Orebody, strict in relation to other dimensions, which cuts oldest rocks occur in the region.
Volcanic Rock
Class of igneous rocks that were ejected or extravasated superfiície the land or close to it.
Water jet
Court system consists of a nozzle that projects a thin jet of pressurized water mixed with an abrasive.
