NOLAN, Director GEOLOGICAL SURVEY PROFESSIONAL PAPER 400 A synopsis ofgeologic results, accompanied by short papers in the geologicalsciences. Publishedseparately as chapters A4 and B UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON :1960 FOREWORD The activities of the United States Geological Survey encompass projects that span the full range of the geological sciences. The volume and complexity of such a research program make it difficult to review, coordinate, and release the results of the work as quickly as is de- sirable; as a result considerable time normally elapses between the completion of many in- vestigations and the publication of the final reports. And yet this same volume and com- plexity make it the more essential that some means be found to digest and make available to all the new ideas and new discoveries that have been achieved. In an effort to help solve this problem the present volume has been prepared; it sum- marizes the results of the recent work of the Geologic Division of the Survey. The report consists of two main parts: Chapter A, "Synopsis of Geologic Results," is primarily a summary of important new findings, either as yet unpublished or published during the fiscal year 1960-the 12 months ending June 30, 1960. It also includes a list of investigations in progress during that period, along with the names and headquarters of those in charge of each, and a list of reports published or otherwise made available to the public during the same period. Chapter B, "Short Papers in the Geological Sciences," consists of 232 papers, generally less than 1,000 words in length. These are of two kinds. Some papers are primarily announce- ments of new discoveries or observations on problems of limited scope, regarding which more detailed and comprehensive reports may or may not be published later. Others summarize the conclusions drawn from extensive investigations that have been in progress for some time; these conclusions in large part will be embodied in much longer reports that will be published later. This report is frankly an experiment. Although both chapters in this volume deal largely with the work of the Geologic Division, it is hoped to expand the scope of the report in future years to include results obtained by other Divisions of the Geological Survey, and to issue it annually. But whether this is done, and whether future issues will be in the same form as this one, depends on how well this volume achieves the purposes described above. Comments and suggestions from those who use the volume will be appreciated and will help determine the content of the future ones. THOMAs B.
