Extension of the Anaconda Metamorphic Core Complex: 40Ar
Extension of the Anaconda metamorphic core complex: 40Ar/39Ar thermochronology and implications for Eocene tectonics of the northern Rocky Mountains and the Boulder batholith David A. Foster1, Warren C. Grice Jr.1,*, and Thomas J. Kalakay2 1DEPARTMENT OF GEOLOGICAL SCIENCES, P.O. BOX 112120, UNIVERSITY OF FLORIDA, GAINESVILLE, FLORIDA 32611, USA 2DEPARTMENT OF GEOLOGY, ROCKY MOUNTAIN COLLEGE, 1511 POLY DRIVE, BILLINGS, MONTANA 59102, USA ABSTRACT Thermochronologic data defi ne the extension and exhumation history of the Anaconda metamorphic core complex and have implications for the Eocene tectonic setting of the northern Rocky Mountains. The 40Ar/ 39Ar data indicate that relatively rapid extension on the Anaconda detachment started at ca. 53 Ma and continued through ca. 39 Ma. Apatite fi ssion-track data reveal that faulting and exhumation of the foot- wall continued until ca. 27 Ma. The average displacement rate on the Anaconda detachment was on the order of 1 mm/yr between ca. 50 and 39 Ma based on the lateral gradient in mica 40Ar/39Ar ages in the direction of fault slip. The total displacement along the Anaconda detachment in Eocene and Oligocene times is estimated to be ≥25–28 km based on reconstruction of the Cretaceous Storm Lake Stock with its detached roof, which is now exposed in the Deer Lodge Valley. Extension exhumed crust from ~12 km depth and exposed middle-greenschist-facies mylonites in the easternmost part of the Anaconda complex footwall. On a regional scale, the Anaconda detachment dips east beneath the Cretaceous Boulder batholith, indicating that the batholith and the Butte mineralization were transported east in the hanging wall. -

MBMG 500-Kelly Lake.FH10
GEOLOGIC MAP OF THE KELLY LAKE 7.5’ QUADRANGLE SOUTHWESTERN MONTANA by Jeffrey D. Lonn and Catherine McDonald Montana Bureau of Mines and Geology Open File Report 500 2004 This report has had preliminary reviews for conformity with Montana Bureau of Mines and Geology’s technical and editorial standards. Partial support has been provided by the STATEMAP component of the National Cooperative Geologic Mapping Program of the U.S. Geological Survey under Contract Number 03HQAG0090. Introduction The Montana Bureau of Mines and Geology selected the Kelly Lake 7.5’ quadrangle for mapping because its excellent alpine exposures in a key locality offer the opportunity to solve some regional stratigraphic and structural problems through 1:24,000-scale mapping. The quadrangle, in the central Anaconda Range of southwestern Montana (figure 1), lies within the hinterland of the Cretaceous Sevier thrust belt. The regionally significant Georgetown thrust (Emmons and Calkins, 1913) bisects the quadrangle into two domains having vastly different stratigraphy. Like the hinterlands of other orogenic belts worldwide, this region experienced a period of significant post-orogenic extension that is represented by the Eocene west-adjacent Bitterroot and east-adjacent Anaconda metamorphic core complexes. Rocks of the Kelly Lake quadrangle lie within the footwall of the recently recognized Anaconda detachment zone (O’Neill and others, 2002, 2004; Kalakay and Lonn, 2002; Lonn and others, 2003; Kalakay and others, 2003), but their complex geology has been previously explained through purely compressional tectonism (Wiswall, 1976; Wallace and others, 1992). The northeastern quarter of the Kelly Lake quadrangle was mapped in detail by Wiswall (1976) and the entire quadrangle was included on both a 1:250,000-scale map (Ruppel and others, 1993) and a 1:50,000-scale map (Wallace and others, 1992).
