_rangingfrom white to pink, tan, yellow
brown, or dark brown. If variableimpurities
causecolor banding in layeredtravertine, the
stone is sometimes called tufa, calcareous
sinter,marble,Metcan onyx, or onyx marble
(Sandersand Friedman, igOZ);true onyx is
banded silica (SiOr).Travertine,as quairied
and marketed by New Mexico Travertine
(NMT), includesall forms of calcite,aragonite, travertine, Mexican onyx, carbonate

oxidized iron on stylolitic surfaces.Mexican
onyx will be called onyx below when used
in textural descriptions.
NMT produces commercial varieties of
stone including Temple Creme (white to
creamy-whitetravertine),Scheherazade
(palecream to pink travertine with onlx), Desert
Creme (yellow to brown travertinewith minor onyx and lilac-or pinkish-graysections),

dimensions for structural, ornamental, or
monumental uses, has becomepopular for
walls, fireplaces, patio floors, and as flagstones,especiallywhere decorativeaccents
and special architectural effects are desired
(Austin et al., 1990).Some segmentsof the
architectural market favor lightly colored
travertine with a relativelyeven, muted texture. Variegated and brightly colored travertine often is consideredless adaptableas
preferred color combinations change over
time. Other architects prefer the more vivid
colors and textures, particularly for interiors
of large buildings.
Travertine in New Mexico
NMT is one of three dimension-stone operations producing travertine in the United
States;the other two are in Idaho and Montana. NMT quarriesabout 400short tons (st)

Travertine is widespread in New Mexico
(Kottlowski, 1965).About 50 discretedeposits are known (Barker,1986,1988)with many
additional ones occurring in the extensiv-e
limestoneterrainsof New Mexico.The nearest large deposit, on trend with the Mesa
Aparejo travertine, is a few miles north of
the NMT quarrieson the LagunaIndian Reservation at Mesa Lucero. Other large occurrences (Fig. 2) are west of Sierra Ladrones
(Barker, 1983)and at Mesa del Oro (ficha,

General geology of Mesa Aparejo
Limestone of the Pennsylvanian Madera
Formation in the subsurface to the west is
probably the primary sourcerock for the carbonate-rich water that formed the Quaternary travertine at the edge of Mesa Aparejo
(Gray Mesa). The lower 800 ft of the Madera
Formation are well exposedjust west of the
NMT travertine quarries (Kelley and Wood,
1946;Titus, 7963;Cooper, 1964)and probably
represent the Gray Mesa Member of the Madera (Kelleyand Wood, 19r[6;Kuesand others,
1982).Other bedrock units nearby include
PennsylvanianSandia Formation, Permian
Abo and YesoFormations, and Precambrian
granite and schist.Kelley and Wood (1945),
summarized by Titus (1953), showed the
structuraland shatigraphicrelationships(Fig.
3) of MesaAparejo (Gray Mesa).Hammond
(1982)summarized regional stratigraphy and
structure south of Mesa Aparejo; Slack and
Campbell (1976)summarized structure to the

is the Comanche thrust fault of Kelley and
Wood (1946),which dips shallowly to steeply
westward. The dip of the fault varies considerably in the vicinity of Mesa Aparejo.
Cooper's interpretation seems correct because it is based on drill-hole data. on observation of the fault plane in outcrop at the
travertine quarries, and is consistentwith
the downdropped Paleozoicsectionjust east
of the fault.

circulationof carbonate-charged
ground water
and spring water.
Precipitation of calcium carbonate in a
spring system occurs when carbonate-rich
waters become supersaturated because of
either evaporation of water or loss of carbon
tabolism (Chafetzand Folk, 1984).Travertine
was deposited as extensive,thick, laminar
lensesat MesaAparejo. Travertinepresently
being deposited-fromsprings just'north of
Mesa Aparejo in secs.35 and 36, T5N, R3W
illustrates one way older and larger deposits
may have formed (Fig. 5).
The varieties of travertine at MesaAparejo
are distinguished by color and structure, but
the mineralogyand origin arefundamentally
the same foi- each. n"eaaingis commonly
laminated with characteristic serrations
probably representing the forward surfaceof
a micro-terraced rimstone dam that impounds a pool of spring water from which
limestone is deposited (Fig. 5). Concretionary massesof various dimensionsare largely
due to algal activity. Rod-like structures, frequently upright and clustered in tufts or
masses/may be algal or bacterialwhen microscopic,but most likely representdeposition around grass,stems, or branches.Holes
1984), are locally abundant.
:a
The highly variable color of the Mesa Aparejo travertine is a result of impurities. Pink
and red are probably primary and result from
inclusion in the travertine of red iron oxide
from nearby Permian sandstone, siltstone,
and shale. Yellow and brown are secondary
and were produced close to the surface by
percolating oxidizing waters during case
hardening and weathering of the travertine.
Onyx is translucent calcium carbonate in
which layers parallel the surfacesof infilled
voids or laminae, and is intimately associated with travertine.Most onyx, now calcite,
w a s d e p o s i t e do r i g i n a l l y a s a r a g o n i t e ,a
metastable higher-temperature form of calcium carbonate. Local coarse-grained aragonite is associatedwith spring orificesmainly
in the Apache Golden Vein portions of the
Gray Mesa Member of the Madera Formation. Becausearagonite is more soluble than
the calcite, advanced dissolution forms soft
crumbly zonesand largevoids later filled with
clay or mud (Cooper, 7964).
Travertine is quarried by NMT for slabs
(typically 4' x 8' sheets,3/q-inchthick) and
ashlar (rectangularpiecesof sawn or roughhewn stoneof non-uniform size).Travertine
fragments are marketed as rubble (roughhewn irregular blocks or boulders)and
crushed stone (broken stone in smaller sizes).

as the cut is made, then is moved forward
and the wire is shortened; this processis
repeatedas often as necessaryto complete
the cut (Fig. 8). The cut may be any orientation from horizontalto vertical.Largeslabs
of rocks are also prepared by a rail-mounted
belt saw that cuts as deep as 10 ft (Fig. 1).
Until recently, most cutting of travertine was
done bv the wire saw' but now much of the
work ii done with great precision and high
output by the'belt saw.
After being broken or cut loose, 150-300st slabs are tipped over using hydraulic
wedges.The blocksfall away from the working face and onto loose debris to lessen
breakage(Fig.9). They aresplit or sawedinto

Quarrying procedures at NMT
Blocks of travertine are cut with a wire
saw, a belt saw or both (Table2). A Vermeer
concretesaw is used to remove caprockoverlying the travertine. During wire-saw operation, intersectingdrill holesproducea path
through which a wire impregnated with industrial diamondsis drawn. The wire is connected in a continuous moving loop and
pulled under tension as it cuts through the
travertine toward a wheel on tracks(Fig. 7).
The wire saw is moved backwardon the track
Milling proceduresat NMT
The NMT finishing plant is about two miles
west of Belenoff Exit 191of Interstate25 (Fig.
2). The Belenplant can produce 2,000to 3,000
ff of travertineslabsper day,but the variable
amount of custom work commonly lowers
output. Gradedand stockpiledquarry blocks
are trimmed square using a small wire saw,
similar to the processat the quarry. Most
blocks at the plant are cut into slabsin an
adjustableGasparigang saw that has as many
as 75 diamond-impregnatedbladesindividually adjustablefor width of cut (Table2, Fig.
10). The gang saw usually is set to produce
3/r-inch-thickslabsthat are then moved to an

The Gregori polishing line removes small
ridges produced by the gang saw, yielding
a smooth, highly polished, flat surface (Fig.
11).During cutting and polishing, the stone
is flushed with water, which removes clay
and mud in the voids. Beforefinal polishing,
a waterproof, appropriately colored grout is
applied, if needed, to the slab surface,filling
the voids and partially cementing the stone.
Epoxy grout has a shiny surfacein polished

Travertine is porous and its physical properties vary more than those of denser materials (Table 3). This is particularly true of
its modulus of elasticity and coefficient of

TABLE 4-Travertine production by New Mexico Travertine. Data in short tons and by commercial
name and product.
Production by NMT
Production recordsof NMT for the last five
years (Table4) show salesof six commercial
varieties of stone and four types of product:
slabs,ashlar,rubble, and cmshed stone.Data
for Desert Gold and Desert Creme are combined. Crushed travertine production was
volatile over the five-year period. Production
trends show a general increase in all travertine varieties since start up (Fig. 14A), particularly for Vista Grande, Temple Crelm,
and Scheherazade.Vista Grande and Desert
Gold,/DesertCremewere very popular in 1982
principally as crushed stone and rubble respectively(Fig. 1aB).Productionof slabs(the
most expensivetravertine product) has risen
substantially for all varieties except Vista
Grande. Temple Creme slabs are the most
popular, but lack of high-quality reserveswill
Iimit future sales. The production of rubble
has varied widely among the five types of
stone used, but Vista Grande is most popular.
Rocky Mountain Stone Company (RMS)
markets stone for NMT. Finished travertine
is displayed at the RMS stoneyard in Albuqlerque on the Pan American Highway
(frontageroad) west of Interstate25 and south
of the fefferson exit. Some travertine is
shipped to sculptors for carving or to marble
shops and dealersprimarily for distribution
to furniture manufacturers. RMS aggressively markets their products in many parts
of the United Statesand has sold large quantities of stone in such distant statesas New
fersey and Washington. RMS travertine
products are now beginning to penehate international stone markets as well.

The future
Vince Lardner, owner of NMT and RMS,
has an interesting oPinion about competition; he wants it. Several established travertine operationsin New Mexicowould helP
expandhis own market by making the state,
as well as his comPanies,better known to
architects for dependable grades and quantities of high-qualitystone.Lardnercautions
that such operations must be well financed,
use the latest technology,and be run by comAugust 1990 Nr.u MexicoGeologY
petent managerswho would actively Pursue
sales.Without that commitment, they would
stand little chance of success.
NMT has large reservesof quality material
near Mesa Aparejo and looks forward to many
more years bf operation. They are developing other travertine deposits in the region.
Given the abundance of travertine occurrences in New Mexico, severalof very good
quality, Lardner may get his wish for competition.
