Abstract

More than 210 rock samples were collected during geologic mapping of the Chiricahua Peak 7 1£-minute quadrangle 

in southeastern Arizona. Energy-dispersive trace-element analyses were conducted for 155 samples, major-oxide abundances were determined for 67 samples, and instrumental 

neutron activation analyses were conducted for 13 samples. 

Miscellaneous wet chemical determinations ( CO2 , FeO, F, 

and CD were made for nine samples. Determinations of Be, Cr, 

Ni, Pb, Sn, and Ag were made for three samples using a combination of spectrographic and wet chemical methods. Semiquantitative spectrographic analyses were obtained for four 

mineralized or altered samples. Standard, and in some cases 

polished, thin sections were prepared for about two-thirds of 

the samples. All of these resources aided map unit characterization. The availability of chemical data, thin sections, and 

hand specimens for each of the samples collected in the quadrangle is tabulated in this report. Information in this report supplements the geologic map of the Chiricahua Peak quadrangle 

(U.S. Geological Survey Geologic Quadrangle Map GQ-1733) 

and supports ongoing investigations of the Turkey Creek 

caldera.

INTRODUCTION

The Chiricahua Peak 7lk -minute quadrangle (fig. 1) 

is east-southeast of Tucson, Ariz., in the Chiricahua Mountains. The quadrangle is located about 70 km southeast of 

Willcox, Ariz. The Chiricahua Peak quadrangle includes 

the crest of the Chiricahua Mountains and offers unusual 

ecologic diversity that ranges from Sonoran desert through 

subalpine environments. Altitudes in the quadrangle range 

from about 1,680 m (5,500 ft) in Rucker Canyon (pi. 1) to 

2,975 m (9,760 ft) at Chiricahua Peak. There are no paved 

roads in the quadrangle. Unpaved roads along Turkey 

Creek, Rucker Canyon, and Price Canyon, located in the 

northwest, southwest, and southeast corners of the quadrangle, respectively, as well as a well-developed trail system 

provide reasonably good access to most of the area.

This report supplements the geologic map of the 

Chiricahua Peak quadrangle (du Bray and Pallister, in

press). It lists the availability of chemical data, thin sections, and hand specimens for each of the samples collected 

in the quadrangle (table 1) and provides tabulations of 

chemical data (tables 2-7) for samples of Tertiary volcanic 

rocks that were collected during geologic mapping of the 

quadrangle. The mapping and data collection are both part 

of a continuing volcanologic study of the Chiricahua 

Mountains in general and of the Turkey Creek caldera in 

particular. The geology of the area has been summarized by 

Pallister and du Bray (1989) and by Pallister and others 

(1990). The data presented here are the subject of a study 

concerning evolution of the Turkey Creek caldera (du Bray 

and Pallister, 1991) and ongoing topical studies.

GENERAL GEOLOGY

Erosion and basin-range faulting in the Chiricahua 

Mountains have exposed multiple levels through the 27-Ma 

(Pallister and du Bray, 1989) Turkey Creek caldera. Parts 

of the 20-km-diameter caldera underlie the northern twothirds of the Chiricahua Peak quao"rangle. Components of 

the caldera exposed in the quadrangle are all of Oligocene 

age and include, from oldest to youngest, intracaldera and 

outflow facies of the Rhyolite Canyon Tuff; dacite porphyry, which forms a resurgent core intrusion and a ring 

intrusion with associated lava flows; and rhyolite (mostly 

lava flows but including some tuff) that fills the caldera 

moat. Stratigraphic, structural, and geochronologic data 

indicate that the porphyry was emplaced soon after the 

Rhyolite Canyon Tuff erupted and that the evolution of the 

caldera, including deposition of the moat deposits was completed in less than 1 million years.

In the Chiricahua Peak quadrangle (du Bray and Pallister, in press), the caldera system is surrounded by, and was 

partly emplaced into, slightly older Tertiary volcanic rocks 

and Cretaceous sedimentary rocks. Outflow tuff from the 

Turkey Creek caldera was deposited on a surface underlain 

by middle Tertiary volcanic (and minor volcaniclastic) 

rocks, including rhyolite ash-flow tuffs and underlying

andesitic to basaltic flow rocks (du Bray and Pallister, in 

press). These rocks are in turn underlain by sedimentary 

rocks, including the formation of Javelina Canyon and 

Bisbee Group rocks. In the Chiricahua Peak quadrangle the 

formation of Javelina Canyon is composed of claystone and 

channel-filling conglomerate. The claystone weathers recessively and rarely crops out, whereas the conglomerate forms 

prominent outcrops. Clasts in the conglomerate are subangular to subrounded and are composed of Bisbee Group rocks, 

Paleozoic formations (principally carbonate sedimentary 

rocks), and intermediate-composition volcanic rocks of 

unknown age. Rocks of the Bisbee Group include the Cintura Formation and the Mural Limestone. The Cintura Formation consists of quartz sandstone, siltstone, and shale. The 

Mural Limestone consists of ledge-forming biostromal

The structural and topographic margins of the Turkey 

Creek caldera are present, in part, in the Chiricahua Peak 

quadrangle. The structural margin consists of the ring fault 

system along which the floor of the developing caldera collapsed during the eruption of the Rhyolite Canyon Tuff.

C2 Geologic Sampling of the Chiricahua Mountains, Arizona

Caldera collapse caused development of a deep central 

depression in which as much as 1.5 km of intracaldera tuff 

accumulated. Outside the structural margin, toward the 

topographic margin, the thickness of intracaldera tuff 

decreases. The structural margin is either concealed by 

younger deposits or has been intruded by dacite porphyry 

throughout most of its extent.

The topographic margin is denoted by the unconformity between caldera fill (intracaldera tuff, wall breccia, 

or moat deposits) and any older rock. The topographic rim 

retreated from the structural margin, by massive landsliding 

into the depression that developed during caldera collapse. 

In this process, large amounts of older rock exposed in the 

walls of the depression presumably calved off and become 

mixed with intracaldera ash to form megabreccia and mesobreccia. As eruption and collapse waned, a thin (<1 km) 

interval of tuff accumulated on the older rock that had 

formed the runout surfaces and headwall scarps of the landslides. The headwall scarps form the topographic margin of 

the caldera and are located outside the structural margin. 

Resurgent emplacement of dacite porphyry magma as a laccolith, ring dike, and lava flows created a caldera moat, 

which subsequently filled with high-silica rhyolite. Moat 

lavas banked against the topographic margin and locally 

overfilled the moat In particular, rhyolite lava flows along 

the northeast-trending ridge of Sage Peak, in the upper 

reaches of Price Canyon, on the ridge south of Baker 

Canyon, and on the east ridge of Dobson Peak, all in the 

southeast corner of the quadrangle (pi. 1), are interpreted as 

moat deposits that flowed across the topographic margin 

after the moat depression in this area was filled by earlier 

moat deposits.

Besides the Turkey Creek caldera, the most prominent 

structural feature in the quadrangle is the north-northwesttrending horst (fig. 1C) in the southwest corner of the quadrangle. Features that suggest the basement block was highstanding following caldera collapse include wall breccia rich 

in clasts from the Bisbee Group. The last motion on the fault 

that bounds the east side of the horst postdates caldera collapse and predates earliest moat magmatism, inasmuch as 

this fault cuts the intracaldera tuff but is buried by moat 

deposits. The northern edge of the horst, 1.5 km south of 

Turtle Mountain and north of Brushy Creek (pi. 1), coincides 

with an exposed segment of the structural margin (a growth 

fault) of the caldera along which the intracaldera fades of the 

Rhyolite Canyon Tuff was deposited. The northern extension of the basement horst is present within the caldera as 

two fault blocks. Offset on the horst- and graben-bounding 

faults indicates a pre-moat lava offset of at least 245 m based 

on the relative elevations of the top of the intracaldera facies 

Rhyolite Canyon Tuff.

ANALYTIC DATA

More than 210 rock samples were collected during 

geologic mapping of the Chiricahua Peak quadrangle. 

Energy-dispersive trace-element analyses were conducted 

for 155 samples. Major-oxide abundances were determined 

for 67 samples. Instrumental neutron activation analyses 

were conducted for 13 samples. Abundances of CO2, FeO, F, 

and Cl were determined for nine samples using various wet 

chemical methods. Abundances of Be, Cr, Ni, Pb, Sn, and 

Ag in three samples were determined using a combination of 

spectrographic and wet chemical methods. Semiquantitative 

spectrographic analyses were obtained for four mineralized 

or altered samples. Most of the chemical data were used to 

aid map unit characterization.

Our sample collecting was designed to provide area! 

representation of the igneous rocks exposed in the quadrangle. By collecting and analyzing numerous samples from 

each map unit we have established the limits of chemical 

variability of these units. This procedure is especially important in sampling ash-flow tuffs, many of which are derived 

from chemically zoned magma chambers (Hildreth, 1981). 

Chemical data also facilitated lithologic/stratigraphic distinctions that in several instances could not be made during 

field investigations.

All of the geochemical data presented here were determined in analytical laboratories of the U.S. Geological 

Survey in Denver, Colo. Major oxide analyses (table 2) were 

performed (analysts, J.E. Taggart, A.J. Bartel, J.S. Mee, and 

D.F. Siems) using X-ray fluorescence techniques (Taggart 

and others, 1987). Fe +:total iron as Fe2+ ratios were 

adjusted to 0.8 and major oxide abundances recalculated to 

100 percent, on an anhydrous basis. Abundances of selected 

trace elements (table 3) were determined (by E.A. du Bray 

and D.B. Yager) by energy-dispersive X-ray fluorescence 

spectroscopy (Elsass and du Bray, 1982) using 109Cd and 

241 Am radio-isotope excitation sources; the accuracy of this 

type of data is discussed by Sawyer and Sargent (1989). 

Abundances of selected trace elements presented in table 4 

were determined (analysts, J.R. Budahn, R.J. Knight, and 

D.M. McKown) by instrumental neutron activation analysis 

(Baedecker and McKown, 1987). Abundances of FeO (as 

ferrous iron), CO2, F, and Cl (table 5) were determined (analysts, E.L. Brandt and J.D. Sharkey) by wet chemistry (Jackson and others, 1987). Abundances of additional trace 

elements (table 6) were determined (analysts, C.J. Skeen and 

M.W. Doughten) by a combination of spectroscopic and wet 

chemical methods. Semiquantitative spectrographic analyses (table 7) of altered or mineralized rock samples were 

obtained (R.T. Hopkins, B.M. Adrian, and M.J. Malcolm, 

analysts) using procedures outlined by Golightly and others 

(1987).
