Geological Survey reports published as Professional Papers, Bulletins, Water Supply Papers, and Circulars are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). This index does not include reports that deal only with administrative matters or that were placed in open files but not formally published.

Reports that deal with Alaska as a whole, with areas that cannot be identified with any specific quadrangle, or with offshore areas that are not within quadrangle boundaries, or that consist mainly of statistical data on the quality or quantity of water are listed under ALASKA - GENERAL, as are bibliographies, indexes, and similar publications. The ALASKA - GENERAL list appears before the alphabetically arranged quadrangle listings.

The U.S. Geological Survey has published a new Geologic Map of the United States (exclusive of Alaska and Hawaii) on a scale of 1:2,500,000, which was compiled between 1967 and 1971 by Philip B. King and Helen M. Beikman, with geologic cartography by Gertrude J. Edmonston. The map replaces the now outdated Geologic Map of the United States on the same scale, which was compiled by George W. Stose and Olof A. Ljungstedt and was issued by the U.S. Geological Survey in 1932.

\n

This report is intended to supplement the new map and to provide background information to assist its user in interpreting it. It describes the historical antecedents of the map and the sources from which the map was compiled and discusses various general topics related to it. Succeeding reports will amplify the necessarily brief descriptions of the map units which appear in its legend and will deal at length with specific geological problems in the United States, insofar as they relate to representation of the features in map form.

Geological Survey reports published as Professional Papers, Bulletins, Water Supply Papers, and Circulars are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 3). This index does not include reports that deal only with administrative matters or that were placed in open files but not formally published.

Reports that deal with Alaska as a whole, with areas that can not be identified with any specific quadrangle, or with offshore areas that are not within quadrangle boundaries, or that consist mainly of statistical data on the quality or quantity of water are listed under ALASKAGENERAL, as are bibliographies, indexes, and similar publications. The ALASKA - GENERAL list appears before the alphabetically arranged quadrangle listings.

Geological Survey maps (other than topographic maps) the publication of which was announced before February, 1974, are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). This index does not include maps that were placed in open files but not formally published, as such maps are listed in another report. References to maps of Alaska as a whole or of offshore areas that are not within quadrangle boundaries are listed under ALASKA - GENERAL, which appears before the alphabetically arranged quadrangle listings.

Geological Survey reports published as Annual Reports, Monographs, Special Reports, Professional Papers, Bulletins, and Water Supply Papers are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). This index does not include any reports that deal solely with administrative matters.

Reports that deal with Alaska as a whole or with areas that can not be identified with any specific quadrangle are listed under ALASKA - GENERAL, as are bibliographies, indexes, and similar publications. The ALASKAGENERAL list appears before the alphabetically arranged quadrangle listings.

The Geological Survey places in open files reports and maps that are preliminary or ephemeral in nature, are of interest to a small audience only, or consist of masses of essentially raw data. These reports and maps are available to the public and may be consulted at various Geological Survey and state offices. Essentially complete files of reports and maps on Alaska are maintained at Geological Survey Public Inquiries Offices in Anchorage, Alaska, San Francisco and Los Angeles, California, Denver, Colorado, and Spokane, Washington; at Geological Survey Libraries in Washington, D. C., Denver, Colorado, and Menlo Park, California; at Geological Survey Alaskan Geology Branch offices in College, Alaska, and Menlo Park, California; at Geological Survey Water Resources Division office in Juneau, Alaska; and at State of Alaska Division of Geological and Geophysical Surveys offices in Anchorage, College, and Juneau, Alaska. Reproducible material from which copies of most of the reports and maps may be made at private expense are available in the Technical Data Unit, Alaskan Geology Branch, U.S. Geological Survey, 345 Middlefield Road, Menlo Park, California 94025.

This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States from 1969 through 1971. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-α ages but is probably 98% complete. Many of the radiometric ages published in abstracts, footnotes, or personal communications are not included as sample localities are lacking or are not sufficiently detailed to be of value. Such ages are often published in a subsequent article with detailed sample locations and geologic interpretation. There may be some duplication of ages in this tabulation. The references listed are either the original source for an age or the best source in regard to sample location, decay constants, interpretation, etc. A few fission-track ages also are listed.

This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States from 1956 through 1964. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-a ages, but is probably 98 percent complete. Many of the radiometric ages published in abstracts, footnotes, or personal communications are not included as sample localities are lacking or are not sufficiently detailed to be of value. Such ages are often published in a subsequent article with detailed sample locations and geologic interpretation. There may be some duplication of ages in this tabulation. The references listed are either the original source for an age or the best source in regard to sample location, decay constants, interpretation, etc. For a tabulation of Pb-a ages published prior to 1957, see U. S. Geological Survey Bulletin 1097-B, Lead-alpha age determinations of accessory minerals of igneous rocks (1953-1957) by H. W. Jaffe, David Gottfried, C. L. Waring, and H. W. Worthing (1959). A minor number of unpublished radiometric ages from Ph.D. or M.S. theses are also listed in this tabulation.

The tabulated ages are systematized according to year and state. All ages published during a specific year (i.e. 1956) are grouped together, with the ages listed under the name of the state in which the sample was collected. The states are alphabetized. The dated sample is described as to rock type, location, material analyzed, age(s) determined, radiometric method used, and published reference (by first author only). The complete reference is listed at the end of the tabulation for each specific year. To answer questions about geologic interpretation, decay constants, or location, one must review the source reference.

This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States and Puerto Rico from 1965 through 1968. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-α ages, but is probably 98 percent complete. Many of the radiometric ages published in abstracts, footnotes, personal communications, and even some articles are not included as sample localities are lacking or are not sufficiently detailed to be of value. Such ages are often published in a subsequent article with detailed sample locations and geologic interpretation. There may be some duplication of ages in this tabulation. The references listed are either the original source for an age or the best source in regard to sample location, decay constants, interpretation, etc. A minor number of unpublished radiometric ages from Ph.D. or M.S. theses are also listed in this tabulation.

The tabulated ages are systematized according to year and state. All ages published during a specific year (i.e. 1965) are grouped together, with the ages listed under the name of the state in which the sample was collected. The states are alphabetized. The dated sample is described as to rock type, location, material analyzed, age(s) determined, radiometric method used, and published reference (by first author only). The complete reference is listed at the end of the tabulation for each specific year. To answer questions about geologic interpretation, decay constants, or location, one must review the source reference.

More than 97 separate occurrences of ultramafic rocks, some of which are included in a north west-trending zone of alpine-type ultramafic rocks, have been mapped in the Eagle quadrangle, east-central Alaska. They are divided into three groups primarily on the basis of degree of serpentinization. Group I consists of lens-shaped bodies of serpentinite 1 m2 (10 ft2) to several 100 m2 (1,000 ft2) in area. Relict textures and presence of bastite indicate that the original rock was harzburgite and dunite. Group II consists of bodies composed of partially serpentinized harzburgite and dunite and includes the large Mount Sorenson and American Creek bodies. Group III is dominantly hornblendite and pyroxenite, probably intrusive and not genetically related to groups I and II. The authors believe that the ultramafic bodies of groups I and II are alpine-type peridotites and may include dismembered ophiolitc. The Tintina fault system could have provided a zone of weakness along which mantle material was tectonically emplaced or it may have been a plate boundary in late Paleozoic time. If it represents a plate boundary, the metamorphic terrane which lies between the Tintina and Denali fault systems would have to be allochthonous, perhaps originating as a northward-moving slice of continental crustal material. During the course of the movement as the two continental masses approached and perhaps collided, mantle peridotite and oceanic crustal material were squeezed up along the continental margin onto the continental slice.

The Foraker and McGonagall plutons, bodies of granodiorite with nearly identical mineralogy and chemistry, are considered to be parts of a single igneous mass that has undergone right-lateral displacement of about 38 km along the McKinley segment of the Denali fault system since the igneous mass crystallized about 38 m.y. ago. These offset plutons place severe constraints on the amount and rate of movement along the McKinley segment since the beginning of the Oligocene Epoch. The 38-km displacement indicates an average rate of 0.1 cm/yr if movement began immediately after crystallization in early Oligocene time or an average rate of 0.4 cm/yr if movement began 10 m.y. ago in late Miocene time. These rates, however, are considerably less than Holocene movement rates measured along the fault further to the east, which suggests that the Holocene displacement rate is greater than the pre-Holocene rate or that right-lateral movement along the fault may diminish to the west.

A comparison of western Aleutian Islands with and without sea otter populations shows that this species is important in determining littoral and sublittoral community structure. Sea otters control herbivorous invertebrate populations. Removal of sea otters causes increased herbivory and ultimately results in the destruction of macrophyte associations. The observations suggest that sea otter reestablishment indirectly affects island fauna associated with macrophyte primary productivity.

A study of 79 chemical analyses of plutonic rocks in the northern part of the Alaska-Aleutian Range batholith shows that K2O and SiO2 in Late Cretaceous and Tertiary rocks decrease toward the Pacific margin and that Al2O3 and CaO increase. Plots for Fe2O3, FeO, MgO, and TiO2 suggest a possible increase toward the Pacific margin; Na2O, H2O+, and MnO show no significant trends across the batholith. Oxide trends for groups of plutons in the western and eastern parts of the batholith in general are opposite that of the groups combined. For the Jurassic plutonic rocks, K2O may decrease toward the Pacific margin; other oxides show considerable scatter, and meaningful trends are not readily apparent. The oxide trends across the batholith are similar to trends across the central Sierra Nevada batholith of California, with the exception of SiO2 and A12O3, which show no significant changes. In the Coast Range batholith of British Columbia, potassium also increases away from the Pacific margin. The increase in K2O toward the continent in the Alaska-Aleutian Range batholith is similar to that found across Quaternary volcanic island arcs, where K2O content increases directly with increasing depth to inclined seismic zones. This increase suggests that generation of magma may have taken place along, or above, a paleoseismic zone. Geologic evidence supports such a model for the Jurassic plutonic rocks, which represent the roots of an early Mesozoic magmatic arc that probably formed above a descending oceanic plate. However, the hypothesis that magma for Late Cretaceous and Tertiary plutonic rocks was generated along seismic zones does not fit available geologic evidence, and an anatectic model cannot be ruled out.

The Border Ranges fault, a major fault of southern Alaska, can be traced for more than 1,000 km arcuately eastward from Kodiak Island to the St. Elias Mountains. Throughout its extent, the fault juxtaposes upper Paleozoic and lower Mesozoic rocks on the north against upper Mesozoic and Tertiary rocks. This report describes the Border Ranges fault and its geologic setting along an approximately 245-km-long segment in the McCarthy and Valdez quadrangles. It also summarizes information relevant to other parts of the fault and discusses its significance and tectonic implications. In the McCarthy and Valdez quadrangles the fault strikes between N. 60° W. and west. Its dips change from vertical and steeply northward in its eastern part to between 20° and 60° north throughout most of the Valdez quadrangle and reflect the transition from a high-angle reverse fault to a northward-dipping thrust. The Border Ranges fault is interpreted to mark a plate boundary that developed near the close of the Mesozoic or in the early Tertiary.
