Minnesota's Mineral Heritage
MINNESOTA'S MINERAL HERITAGE CONSERVATION BULLETIN NUMBER TWELVE MINNESOTA OF CONSERVATION This document is made available electronically by the Minnesota Legislative Reference Library as part of an ongoing digital archiving project. http://www.leg.state.mn.us/lrl/lrl.asp (Funding for document digitization was provided, in part, by a grant from the Minnesota Historical & Cultural Heritage Program.) Author's Foreword Our natural resources constitute the foundations· of our well-being. the means of our protection, the hope of our future. The resources of any region determine to a marked degree .the activity of its inhabitants. Minnesota, though known as an agricultural state, has great mineral wealth and many of its citizens are engaged in mineral industries. Only ten states exceed Minnesota in the value of their annual mineral output. Of these ten, six are the great oil-producing states, three are the coal-producting states of Pennsylvania, West Virginia and Illinois, and one is California with its oil and gold. All of the mineral substances produced from the rocks of the states may be considered industrial minerals. Some are metals and others are non-metals. Metal mining· is restricted to the iron ranges, but the non-metals include a great variety of materials, such as limestone, agricultural lime, dolomite, marl, sand and gravel, clays and shales, wool rock, structural and architectural stone, etc., which are excavated and processed at many different places in the state. In the preparation of the articles in this bulletin, the main objective of the author was to acquaint the citizens of the state with the nature and extent of our mineral heritage. -

M. Bristol and Ronald Prescott ABSTRACT The Tuscola Anticline, in east-central Illinois, lies astride the complex LaSalle Anticlinal Belt and dips steeply westward into the Fairfield Basin and gradually eastward into the Murdock Syncline. The anticline is broken into two structural highs, the Hayes Dome and the Shaw Dome. Pleistocene sediments, 50 to 250 feet thick, cover the area. Pennsylvanian sediments cover much of the area, thinning to expose an inlier of Mississippian, Devonian, and Silurian rock north of Tuscola. The basal Cambrian for- mation, the Mt. Simon Sandstone, is penetrated by only two wells. Oil production from the Kimmswick (Trenton) com- menced in 1962 from the R. D. Ernest No. 1 Schweighart well, near Hayes, and as of January 1, 1968, approximately 30 wells were producing oil. Cumulative oil production as of January 1, 1968, is approximately 94,000 barrels. The potential pay zone is confined to the upper 5 to 100 feet of structure and to the upper 125 feet of the Kimmswick, whose permeability ranges from 0.1 to 2. millidarcys, av- eraging 0.6, and whose porosity ranges from 2 to 12 per- cent. -
Mineralogy and Origin of the Titanium

Depardnent of loggand Geophysics, May 18, 1962 Certified by Thesis Supervisor Ab Accepted by ...... Chairman, Departmental Committee on Graduate Students M Abstract Mineralogy and Origin of the Titanium Deposit at Pluma Hidalgo, Oaxaca, Mexico by Edwin G. Paulson "Submitted to the Department of Geology and Geophysics on May 18, 1962 in partial fulfillment of the requirements for the degree of Master of Science." The Pluma Hidalgo titanium deposits are located in the southern part of the State of Oaxaca, Mexico, in an area noted for its rugged terrain, dense vegetation and high rainfall. Little is known of the general and structural geology of the region. The country rocks in the area are a series of gneisses containing quartz, feldspar, and ferromagnesians as the dominant minerals. These gneisses bear some resemblance to granulites as described in the literature. Titanium minerals, ilmenite and rutile, occur as disseminated crystals in the country rock, which seems to grade into more massive and large replacement bodies, in places controlled by faulting and fracturing. Propylitization is the main type of alteration. The mineralogy of the area is considered in some detail. It is remarkably similar to that found at the Nelson County, Virginia, titanium deposits. The main minerals are oligoclase - andesine antiperthite, oligoclase- andesine, microcline, quartz, augite, amphibole, chlorite, sericite, clinozoi- site, ilmenite, rutile, and apatite. -

Weathering of Ilmenite from Granite and Chlorite Schist in the Georgia Piedmont
American Mineralogist, Volume 87, pages 1616–1625, 2002 Weathering of ilmenite from granite and chlorite schist in the Georgia Piedmont PAUL A. SCHROEDER,* JOHN J. LE GOLVAN, AND MICHAEL F. RODEN Department of Geology, University of Georgia, Athens, Georgia 30602-2501, U.S.A. ABSTRACT Ilmenite grains from weathering profiles developed on granite and ultramafic chlorite schist in the Georgia Piedmont were studied for evidence of morphological and chemical alteration. Ilmenite- rich concentrates from the fine sand (90–150 mm) component were studied to test the assumption that there is no difference between ilmenite in the parent rock and that in colluvium delivered to primary drainage systems. Ilmenite grains in the granite profile are rounded to subhedral, and commonly contain hematite exsolution blebs. Dissolution pits are observed along the boundaries of the exsolution blebs, with goethite occurring as an alteration product. Ilmenite grains in the schist profile occur as fractured anhedral grains with uncommon lamellae of rutile. Grain fractures are filled with goethite and he- matite, particularly in the B-horizon. Ilmenite from the granite profile is Mn rich (7–15 mol% MnTiO3), whereas ilmenite from the schist profile contains only 1–2 mol% MnTiO3 and up to 8 mol% MgTiO3. Two populations of grains develop in both profiles. Grains with abundant exsolution blebs and fractures alter through a proposed two-step reaction mechanism. It is proposed that il- menite first undergoes a solid-state transformation to pseudorutile via an anodic oxidation mecha- nism. Oxidized Fe and Mn diffuse from the structure and precipitate as goethite and MnO2. Pseudorutile is ephemeral and undergoes incongruent dissolution to form anatase, hematite, and goethite. -

It provides an integrated study approach by correlating the geochemistry of the lithology and hydrochemical data of groundwater samples. Mineralogical analysis showed that all of the samples were dominantly composed of either calcite CaCO3 (5–100 wt. %) or dolomite CaMg(CO3)2 (4–100 wt. %), with minor amounts of quartz and feldspar, which is supported by the inorganic carbon content (9–13 wt. %) and hydrochemical composition of the spring water samples. The whole-rock geochemical data indicated that the samples have low contents of trace elements and transition metals. In contrast, the concentrations of alkaline earth elements (Mg, Ca, Sr, Ba) and Mn were high in the rock and groundwater samples. Generally, the trace elements of rock samples with concentrations >10 ppm included Sr (17–330 ppm), Mn (17–367 ppm), Ba (2–32 ppm), W (5–37 ppm), Cr (3–23 ppm), Zn (1.7–28 ppm), V (4–23 ppm), and Zr (1–22 ppm), while the concentrations of all the other trace elements was below 10 ppm. -
