Excerpt from The Geology and Ore Deposits of the Virgilina District of Virginia and North Carolina In order to insure uniformity for the district as a whole, the same geologist, Doctor Francis B. Laney, was employed by the Virginia and North Carolina Geological Surveys to make the survey in the two states under the general supervision of the State Geologists of Virginia and North Carolina. Doctor Laney was assisted in the field work in North Carolina for a part of the time by Doctor Joseph E. Pogue, of the North Carolina Geological and Economic Survey, and, in Virginia, by Mr. Joel H. Watkins, of the Virginia Geological Survey. The investigation covers an area of approximately 550 square miles, including parts of Charlotte, Halifax, and Mecklenburg counties, Virginia, and parts of Granville and Person counties, North Carolina. Chapter I gives a short but concise geographic sketch of the district, including loca tion, topography, drainage, soil, and climate, closing with a complete account of previous geologic work in the district in the form chie¿y of an annotated bibliography. Chapters II and III discuss the general geology of the district and give a detailed description and classification of the rocks, their structure and metamorphism. Chapter IV comprises a detailed description of the veins and ores, in which the mineralogy of the ore and gangue minerals is fully described, and the relations of the copper-bearing sulphides to each other and the origin and deposition of the ores are dis cussed. Chapter V, entitled, The Mines and Ores of the Virgilina District, gives a full description of the individual mines and prospects.
