The petrogenesis of the alkaline rocks of the Judith Mountains, central Montana by Paula Jean Barrick A thesis submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Earth Science Montana State University © Copyright by Paula Jean Barrick (1982) Abstract: The Judith Mountains are part of the central Montana alkaline province. , Intrusive igneous activity began in the Judith Mountains about 68-69 m.y. ago with the emplacement of alkali-calcic plutons. Volume-trically minor but widespread alkaline igneous rocks were intruded 62-65 m.y. ago in the same terrane. This study focuses on the origin of the second (alkaline) intrusive event, which emplaced two different suites of alkaline igneous rocks. The alkaline rocks are divided into two groups based on silica saturation: 1) a quartz-bearing assemblage consisting of syenite which contains xenoliths of alkali gabbro; and 2) a nepheline-bearing assemblage which includes tinguaite (a textural variety of nepheline syenite) and xenoliths of nepheline pyroxenite or ijolite. The two assemblages may be termed "mildly" and "strongly" alkaline. The parent magma may have been kimberlite, since carbonatite-kimberlite magmas are known elsewhere in the province and local alteration (fenitization) suggests the presence of a buried carbonatite body. However, quartz-bearing alkaline rocks cannot be derived from an undersaturated kimberlitic magma except under certain special conditions. Therefore, the mildly and strongly alkaline rocks either formed from separate parent magmas, or formed from a single parent magma under two very different sets of conditions. The nearly contemporaneous emplacement of the two groups suggests a single parent magma pulse. -

Controls on Ore Deposition, Polaris Mining District, Pioneer Mountains
Controls on ore deposition, Polaris mining district, Pioneer Mountains, Beaverhead County, Montana by Thomas Edward Davis A thesis submitted in partial fulfullment of the requirements for the degree of MASTER OF SCIENCE in Earth Sciences Montana State University © Copyright by Thomas Edward Davis (1980) Abstract: The Polaris silver mining district is located along the southern margin of the Cretaceous Pioneer batholith. The silver ore replaces Mississippian age Madison Group limestone though in other districts of the Pioneer region Cambrian carbonates may also be mineralized. Other stratigraphic units present in the Pioneer district are the Precambrian Missoula Group and the Cambrian Meagher, Park, and Pilgrim Formations. These strata underwent six stages of faulting, probably during the Laramide orogeny. In chronological order, the fault systems strike: N 33° W; N-S; E-W; N 60° E; N 40° E; and N-S. A N-S fold set formed after the first stage of faulting, and an E-W fold set developed after all faulting. A third folding episode, evident only underground, has folded the Polaris (N 60° E) fault. The batholith intruded passively after the fifth and perhaps after the sixth episode of faulting. Ore mineralization is presumed to have followed intrusion of the batholith, at least of its deeper levels, by analogy with other ore districts in the Pioneer region. Ore replaces Madison Group limestone along N 60° E faults; only these faults were open at the time of mineralization since they were parallel to the direction of maximum stress. In the Polaris Mine, the principal mine of the district, the paragenetic sequence of mineralization is: pyrite, sphalerite; galena; pyrargyrite(?); and native silver. -

Chapter 3 Affecte Nvironm T
CHAPTER 3 AFFECTE NVIRONM T Chapter 3 describes existing conditions in the Garnet Resource Area that will be affected by resource man- agement options. The information in this chapter is a summary of the Garnet Resource Area Management Situation Analysis (MSA). The MSA is available for review at the Garnet Resource Area office. SETTING The Garnet Resource Area (GRA) includes the nine northwestern counties of Montana (see the Percent of Public Surface Ownership map). Of these nine, only three counties have a large amount of public land: Missoula, Granite, and Powell. Therefore this chap- ter will focus on the core area formed by these three counties. The core area has timbered mountain ranges with narrow canyons. The ranges are separated by the Clark Fork and Blackfoot rivers and lie between the Bob Marshall Wilderness area to the north and the Anaconda/Pintler Range to the south. The city of Missoula is west of the core area and Helena, east (see the Land Status map in the map packet). There is a total of 4,277,120 acres in the three coun- ties. The Garnet Resource Area manages 145,660 acres. The GRA is part of the Butte District, which was organized in 1976. The resource area was named for the Garnet Mountain Range. Other large landholders in the core area are the Lo10 and Deerlodge National Forests; Plum Creek Timber Company Inc.; Champion Timberlands; the Depart- ment of State Lands; the University of Montana, School of Forestry; and the Montana State Prison Ranch. Most of the lands are rural in character with forestry and agriculture being the most important resource uses. -
GEOLOGIC MAP of the PLAINS 30'X 60' QUADRANGLE
GEOLOGIC MAP OF THE PLAINS 30’x 60’ QUADRANGLE, WESTERN MONTANA Jeffrey D. Lonn, Larry N. Smith, and Robin B. McCulloch Montana Bureau of Mines and Geology Open-File Report 554 2007 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 06HQAG0029. INTRODUCTION Montana Bureau of Mines and Geology (MBMG) staff selected the Plains 30’x 60’ quadrangle in western Montana for 1:100,000-scale mapping in order to fill the gap between the already completed Wallace (Lonn and McFaddan, 1999) and Missoula West (Lewis, 1998a) 30’x 60’ quadrangles (fig. 1). Bedrock of the map area is comprised mostly of low-grade metasedimentary rocks of the middle Proterozoic Belt Supergroup. The extraordinary thickness (>13 kilometers) of the Belt Supergroup and its complex deformation in western Montana have contributed to substantial stratigraphic and structural complexity in this region, and a geologically sound regional interpretation for this part of western Montana has been a goal of MBMG’s mapping program for the past decade. Harrison and others (1986) provided the foundation for mapping in this area with the publication of the Wallace 1O x 2O quadrangle, a 1:250,000-scale compilation that includes the Plains 30’ x 60’ quadrangle. The southwestern third of the Plains quadrangle contains structures of the Lewis and Clark Line, a poorly understood zone of west- northwest-trending faults and folds that transects the more northerly structural grain of western Montana (fig. -
