SLATON, Governor and President of the Advisory Board of the Geological Survey of Georgia. SIR: I have the honor to transmit herewith the report of Dr. S. L. Galpin, Assistant State Geologist, on the Feldspar and Mica Deposits of Georgia, to be published as Bulletin No. 30 of this Survey. Very respectfully yours, S. W. McCALLIE, State Geologist. PREFACE The preparation of this report was authorized for the purpose of obtaining and supplying to the public, information regarding the occurrence and nature of the feldspar and mica deposits which exist in the State. That such information is in great demand is shown by the frequent inquiries concerning these minerals addressed to the Geological Survey. The report contains, in addition to descriptions of feldspar and mica deposits, one chapter dealing with the general geology of the .area in which these deposits occur, and a second detailing the nature of the rock pegmatite and the uses, values, and the like, of its most important minerals, particularly feldspar and mica. The collecting of this material was begun in May, 1912,. and con­ tinued until January, 1914. Much of the information was obtained .at first hand either in the field or from laboratory study. The re­ mainder has been collected from various sources which are indicated in the text by foot notes whenever possible to do so. Progress on the report was halted in January, 1914, by the writer's "Withdrawal from the active staff of the Survey. However, arrange­ ·ments were later perfected whereby he has been allowed to complete the work. He takes this opportunity to acknowledge the Survey's ·cordial co-operation, which has been a very material aid in the re­ -port's preparation. s. L.

The deposit is confined within a felsic tuff unit; about 10 meters thick where sampled for chemical analysis. Using XRF, EDS and XRD techniques, we found besides todorokite, cryptomelane, quartz, romanechite (psilomelane), birnessite, illite-muscovite, cristobalite, chlorite, barite, halloysite, woodruffite, nacrite or kaolinite, and possibly hollandite-ferrian, as well as an amorphous material and two unknown manganese phases.

  • BATTLE of KETTLE CREEK Remarks of Judge Ed Butler, Secretary General, NSSAR, Principal Speaker, Kettle Creek Battle Ceremonies, at the Pope Center on Feb
    BATTLE OF KETTLE CREEK Remarks of Judge Ed Butler, Secretary General, NSSAR, principal speaker, Kettle Creek Battle ceremonies, at the Pope Center on Feb. 14, 2009, in Washington, GA. President Towns, distinguished guests, ladies and gentlemen. We are here today to honor the memory of the Georgia patriots who fought near here 230 years ago today. Through their courage and determination, they defeated an army with over twice as many men under arms. The Battle of Kettle Creek was the most important battle of the American Revolutionary War to be fought in Georgia. The battle was fought on February 14, 1779, near this location at Battle Hill. The victory by the American Patriot Militia virtually ended the movement to remain loyal to the England among Georgians. Loyalist and neutral Georgians were no longer vocal opponents. The Patriot force that engaged a larger Tory Militia force was led by Colonels Andrew Pickens, who later was promoted to General; John Dooly, who was later murdered by British regulars; and Elijah Clarke, who was also later promoted to General. Andrew Pickens lead his own force of 200 militiamen and was joined by the force of100- 140 militiamen led by John Dooly. Together, these 300-340 men launched a surprise attack on the Tory force of 700 men led by Colonel James Boyd. Pickens' force circled and followed the Tory force without their knowledge until he launched the surprise attack on February 14, 1779. The encamped Tories were not wholly surprised, as their pickets fired upon approaching Patriot scouts. Thereafter, a fierce battle ensued and Tory leader James Boyd was killed.

  • Georgia Government 1 (PDF)
    Georgia Government Summary Dr. Sarah Kuck and Mr. Roger Marietta Introduction Georgia’s state government was formed in 1776, and since that time the State Constitution has been rewritten 10 times and amended hundreds of times. To amend the Georgia Constitution today, both houses of the Georgia General Assembly must pass the proposed Constitutional amendment by a two-thirds vote. The amendment ratification is voted on by the people in the next general election, and a majority of the voters must approve. Georgia’s state government and its politics have been shaped by its history. 2011 is the sesquicentennial of the beginning of the Civil War. President Lincoln and General Sherman, as hated Republicans, left a simmering anger as the Civil War and slavery came to an end. The Democratic Party dominated Georgia politics until the period after the Civil War known as Reconstruction. Reconstruction brought the freed slaves into the political process as Republicans, and they gained many elected offices from 1865 until 1877. When the Posse Comitatus Act was passed by Congress and Federal troops could no longer enforce state and local laws, the political winds shifted. From 1877 until 1954, “Jim Crow” laws enforced segregation in Georgia while the Democrats dominated the politics of Georgia under the banner of “state rights”. Many Caucasian voters in Georgia were “Yellow Dog” Democrats – they would vote Democrat even if the candidate was a yellow dog. With the Supreme Court’s reversal of Plessy v Ferguson as a result of Brown v Board of Education of Topeka Kansas, coupled with the emergence of Dr.

  • MINERALOGY for PETROLOGISTS Comprising a Guidebook and a Full Color CD-ROM, This Reference Set Offers Illustrated Essentials to Study Mineralogy, Applied to Petrology
    MINERALOGY for PETROLOGISTS for MINERALOGY Comprising a guidebook and a full color CD-ROM, this reference set offers illustrated essentials to study mineralogy, applied to petrology. While there are some excellent reference works available on this subject, this work is unique for its data richness and its visual character. MINERALOGY for PETROLOGISTS With a collection of images that excels both in detail and aesthetics, 151 minerals are presented in more than 400 plates. Different facies and paragenesis, both in natural polarized light, are shown for every mineral and optical data, sketches of the crystal habitus, chemical composition, occurrence and a brief description are Optics, Chemistry and Occurrences included. The accompanying user guide gives a general introduction to microscope mineral observation, systematic mineralogy, mineral chemistry, occurrence, of Rock-Forming Minerals stability, paragenesis, structural formula calculation and its use in petrology. This compact set will serve as a field manual to students, researchers and Michel Demange professionals in geology, geological, mining, and mineral resources engineering to observe and determine minerals in their studies or field work. Dr. Michel Demange has devoted his career to regional geology and tectonics of metamorphic and magmatic terranes and to ore deposits. Graduated from the École Nationale Supérieure des Mines de Paris and holding a Docteur-es-Sciences from the University Pierre et Marie Curie, Paris VI, he has been active in a rich variety of geological projects and investigations around the world. In combination with his teaching and research activities at the École des Mines in Paris, France, he headed various research studies. This book benefits from the great experience in field M.
