Index . 65 BIBLIOGRAPHY OF VIRGINIA GEOLOGY AND MII\I-ERAL RESOURCES-T9sO.T9sg By F. B. Hoprsn

INTRODUCTION

Two bibliographies dealing with Virginia geology and mineral resources have been previously published:

(1) Annotated geological bibliography of Virginia: Charlottesville, Alderman Library; Richmond, Dietz Press, 726 p.,l942,by J.K. Roberts; (2) Bibliography of Virginia geology and mineral resources-l94l- 1949; Virginia Division of Mineral Resources Information Cir- cular 14, 58 p., 1968, by F. B. Hoffer.

The present bibliography is patterned after the Bibliography of North American Geology, which is published annually by the United States Geological Survey. It lists the literature on the geology and mineral resources released from 1950 through 1959, plus some ornissions from earlier bibliographies. Readers are encouraged to notify the Vir- ginia Division of Mineral Resources of any omissions and etrors in this bibliography so that corrections may be included in later supplements. Theses from colleges and universities in the United States and open-file reports which include data pertaining to the Commonwealth of Vir- ginia are listed. Where a report deals with more than three counties, it is entered in the index under Virginia or a subdivision of the Commonwealth, or under one of the physiographic provinces. Abbreviations in the cita- tions are restricted to those commonly known or used in the United States Geological Survey Bibliography of North America. VrncrNre DrvrsroN or MrNenar Rmounces
