RABBITT, DOROTHY B. VITALIANO, S. T. VESSELOWSEY, and others INTRODUCTION EXTENT OF COVERAGE Geophysical Abstracts includes abstracts of technical papers and books on the physics of the solid earth, the application of physical methods and techniques to geologic problems, and geophysical explora tion. The table of contents, which is alphabetically arranged, shows the material covered. Abstracts are prepared only of material that is believed to be gener ally available. Ordinarily abstracts are not published of material with limited circulation (such as dissertations, open-file report®, or memoranda) or of other papers presented orally at meetings unless summaries of substantial length are published. Abstracts of papers in Japanese and Chinese are based on abstracts or summaries in a western language accompanying the paper. LIST OF JOURNALS The following list supplements the List of Journals published in Geophysical Abstracts 160 (January-March 1955, Bulletin 1033-A) and the supplements published in Geophysical Abstracts 161,162, !££, 164, and 165.

FORM OF CITATION The abbreviations of journal titles used are those adopted by the U. S. Geological Survey and used in many geological journals. For papers in most languages other than English, the title is given in the original language as well as in translation. Slavic names and titles have been transliterated by the system used by the United States Board on Geographic Names. This system of transliteration for Russian was given in Geophysical Abstracts 148 (January-March 1952, Bulletin 991-A). Titles of papers in Japanese and Chinese are given in translation only. ABSTRACTORS Abstracts have been prepared by J. R. Balsley, P. E. Byerly, W. H. Diment, R. G. Henderson, D. R. Mabey, Virginia S. Neuschel, L. C. Pakiser, and Isidore Zietz as well as by the principal authors. The notation "Author's summary" followed by the initials of an ab stractor indicates a translation of the author's summary.

No traces remain of the geologic effects of these variations. Yearly changes of climate are noticeable in the varve sediments of the las't glaciation or in the argillaceous bands in southern Altai Mountains or in Scandinavia. Longer periods have been suggested, such as 2.7, 3.5, 5.9, and 11.35 years in the sediments of southern Urals, in the Precambrian formations of Yenisei Ridge, and in Finland and Chile, for example. A period of 21,000 years, corresponding to the precession of equinox, has been repeatedly mentioned, but no geologic phenomena corresponding to this astronomic phenomenon were ever positively established. Comparison of the,time intervals between glacial periods suggests some correlation between them and the galactic year; that is, the full revolution of the solar system around the galactic center.
