  • Mineralogy of the Peraluminous Spruce Pine Plutonic Suite
    MINERALOGY OF THE PERALUMINOUS SPRUCE PINE PLUTONIC SUITE, MITCHELL, AVERY, AND YANCEY COUNTIES, NORTH CAROLINA by William Brian Veal (Under the Direction of Samuel E. Swanson) ABSTRACT The Spruce Pine plutonic suite consists of numerous Devonian (390-410 ma) peraluminous granitic plutons, dikes, sills, and associated pegmatites. The mineralogy of pegmatites and host granodiorites from seven locations was studied to determine the extent of fractionation of the pegmatites relative to the granodiorite. Garnets in the plutons are almandine- spessartine and some display epitaxial overgrowths of grossular garnet. Similar garnets are found in the pegmatites. Pegmatitic muscovite contains several percent iron and is compositionally similar to muscovite from the host granodiorite. Feldspars in the granodiorites and pegmatites are compositionally similar (plagioclase Ab69-98; k-feldspar Or95-98). The lack of compositional variation between minerals in pegmatites and host granodiorites indicates the pegmatites were not the result of extreme fractionation and indicates that pegmatite mineralogy can be used to characterize the mineralogy of an entire granodiorite body.

You have also learnt that the slow cooling of magma takes place in the deeper parts of the Earth and large size crystals are formed. On the contrary, magma undergoing rapid cooling in shallower depth or on the surface of the Earth yielded fine grained crystals. The rapid cooling of lava/melt molten rock on the surface of the Earth produces fine grained minerals or glass. The igneous rocks vary in grain size from very coarse, medium to fine grained or even glassy in hand specimen and under the microscope. Thus, igneous rocks display variety of textures. Thus, the term texture refers to physical appearance of a rock. In this unit we will discuss textures and structures of igneous rocks.

  • Bedrock Geology and Geochemical Analysis of the Bowdoinham 7.5' Quadrangle, Southwestern Maine
    Bedrock Geology and Geochemical Analysis of the Bowdoinham 7.5’ Quadrangle, southwestern Maine Joel Frank Cubley Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Arts Department of Geology Middlebury College Middlebury, Vermont April 2005 Bedrock Geology and Geochemical Analysis of the Bowdoinham 7.5’ Quadrangle, southwestern Maine Joel Cubley, Department of Geology Middlebury College, Middlebury, Vermont 05753 The Bowdoinham 7.5’ quadrangle, located in southwestern Maine, is situated along the boundary between the regionally extensive Liberty-Orrington and central Maine lithotectonic belts. Detailed 1:24,000 scale bedrock mapping in the northern half of the quadrangle has resulted in the delineation of the following lithologic units (described from west to east): (1) interlayered biotite granofels and calc-silicate gneisses of the Silurian-Devonian Vassalboro Formation (central Maine sequence), (2) a previously unrecognized, deformed and recrystallized Devonian metagranitoid pluton hereby named the Hornbeam Hill Intrusive Suite, (3) migmatitic biotite gneisses and other subordinate lithologies (e.g. amphibolites, rusty schists) associated with the Ordovician Falmouth-Brunswick sequence (Liberty-Orrington belt), and (4) several small but mappable granitic pegmatite bodies of both Devonian and Permian age. The Hornbeam Hill Intrusive Suite is significant because it stitches the contact between the Vassalboro Formation and Falmouth-Brunswick sequence rocks. Thin dikes and sills of Mesozoic diabase are found in the study area, but cannot be mapped at this scale. Stratified rocks in the quadrangle have been penetratively deformed, folded, and metamorphosed to upper amphibolite conditions during the Acadian orogeny. A pervasive east-dipping foliation (generally <45º) can be found in rocks of both lithotectonic belts, as well as the Hornbeam Hill Intrusive Suite, implying that the dominant episode of deformation in this region occurred after the emplacement of that pluton.

The felsic dykes increase in size and density towards the contact, but are truncated with brecciated Burra Group sediments. Monzogabbro body is dominated by coarse grained euhedral arnphibole and smaller clinopyroxene. Dykes are thought to have originated by a fil-ter- pressínq mechanism where late-stage residual fel-sic rnelt is progressively squeezed out towards the margin of a ferromagnesian crystal-rich maqma.

    ME589/Geol571 Advanced Topics Geology and Economics of Strategic and Critical Minerals Commodities Commodities—Be and Te Virginia T. McLemore Comments on Quiz • What are the differences between the Lemitar and Mountain Pass carbonatites? – Mt. Pass is in production, Lemitar is beginning exploration • What is the advantage of producing REE from nontraditional deposits such as phosphate, breccia pipe, coal, sandstone uranium deposits? – These other deposits could have more tonnage being produced and could considerably add to the total REE being produced • Why is important for exploration geologists to understand the processing and environmental issues associated with REE and critical minerals? – Ultimately the producer needs a social license to operate (the community needs to be supportive of the operation) – Exploration geologist are the first in the area that can identify potential problems What is beryllium? What is beryllium? • Beryllium – Average of 0.52 mg/kg in soil – Occurs as minerals, trace Beryllium metal concentrations in other minerals Beryllium ore Beryllium oxide Beryllium alloys Beryllium • 4th element on the periodic table • 44th element in abundance • Gemstone • low density (1.85 grams/cubic centimeter) • it has a very high melting point: 1,278° C • resistance to creep, shear strength, tensile strength, comprehensive yield strength and just its fracture toughness Beryllium—Properties • Low absorption cross-section with respect to thermal neutrons • Light element • Ability to withstand extreme heat • Remain stable over
