ii i CORRELATION OF CENOZOIC STRATIGRAPHIC UNITS OF WESTERN OREGON AND WASHINGTON

Correlation of rock units is a fundamental data base for interpreting earth history. The chart accompanying this report is a graphical display of current knowledge by thirty stratigraphers on the correlation of the Cenozoic stratigraphic units of twenty local successions in western Oregon and Washington ( see Exhibits 1, 2, and 3). The local successions are correlated to both provincial and global chronostratigraphic units.

The new correlation chart, "Correlation of Cenozoic Stratigraphic Units of Hestern Oregon and Washington, " revises part of the 1944 chart "Correlation of the Marine Cenozoic Formations of Western North America," constructed under the chairmanship of C. E. Weaver and published by the Geological Society of America.

Correlations shown on the new chart differ from many previously published reports. The changes reflect two origins:

1) New data that change or refine previous correlations; and 2 ) Changes in the local usage of the European series-epoch and stage-age units.

Access to new data is facilitated by the data sheets for individual stratigraphic units. The data sheets have been provided by the geologists contributing to the construction of the local stratigraphic columns . Each data sheet consists of basic nomenclatural, stratigraphical, and biostratigraphical information including references for the first use of the stratigraphic unit and a "most useful" publication. Use of the data sheets and the references cited thereon is essential to the correct usage of the correlation chart.

Changes in European series-epoch and stage-age usage result from the recalibration of Oregon and Washington biostratigraphic and

- 1 - chronostratigraphic units to the global chronostratigraphic units. This recalibration has been accomplished by redefinition of local zonal and stage units and their correlation, through the use of new data on planktonic microfossils collected from local stratigraphic units, to the planktonic zonal schemes of the worldwide geologic time scale. The biostratigraphic correlations are augmented by integration of radiometric ages (see Armentrout, 1981).

The refinement of correlation between provincial and global chrono stratigraphic units requires reevaluation of previously published Oregon-Washington usage of European series-epoch and stage-age units . A case in point are those formations containing foraminiferal faunas assigned to the Narizian and Refugian Foraminiferal Stages . Based on the best data available, Weaver and others (1944) correlated the Narizian Stage to the late Eocene and the Refugian Stage to the Eocene-Oligocene . Recent work incorporating planktonic microfossil faunas recovered from the same strata as the benthic foraminifers has shown that the Narizian best corre lates with the middle to early late Eocene, and the Refugian best correlates with the late Eocene (Armentrout, 1981; Rau, 1981; Warren and Newell, 1981).

Geologists must identify the basis of published age assignments, including the time scale used by the original author, and reevaluate that data in light of current correlation frameworks. Reevaluation of provincial usage of European terms is facilitated by inclusion of both global and provincial chronostratigraphic frameworks on the "Correlation of Cenozoic Strati graphic Units of Western Oregon and Washington" chart and by use of the information on the stratigraphic unit data sheets .

The construction of this chart, "Correlation of Cenozoic Stratigraphic Units of Western Oregon and Washington," has been a cooperative effort of the Oregon Department of Geology and t·1ineral Industries and the Washington Department of Natural Resources - Geology and Earth Resources Division. Development of the Oregon-�Jashington chart is part of a national project entitled "Correlation of Stratigraphic Units of North America" (COSUNA).

-2- COSUNA is a research project of the American Association of Petroleum Geologists in cooperation with the United States Geological Survey and the Geological Society of America. The COSUNA project began in 1976 and is concluding during 1983 with the publication of a series of regional correlation charts. These charts are intended to serve as replacements for the sixteen correlation charts published as Bulletins of the Geological Society of America during 1942-1960.

Publication of the COSUNA charts is coordinated by 0. E. Childs, A. Salvador and G. Steel. Childs, in his 1981 Annual Report on the COSUNA project, noted that G. Arthur Cooper, senior author of the 1942 Correlation Chart #4, admonished chart users to remember that "Many of the correlations are only tentative; the reader is warned not to accept the chart as a final or fixed expression of correlations; it is a statement of existing knowledge only. " The publication of a new correlation chart series in the 1980's provides a new "tentative" statement of existing knowledge reflect ing the ever-increasing understanding of the stratigraphic record .

To facilitate understanding of the present chart for the "Correlation of Cenozoic Stratigraphic Units of Western Oregon and Washington," the following aspects of chart construction are noted:

1. The "Correlation of Stratigraphic Units of North America" (COSUNA) project provides a series of correlation charts using a uniforr.1 time scale to facilitate correlation of stratigraphic units between different geographic regions of North Ar.1erica. While the correlation of global chronostratigraphic units continues to undergo modification and recalibration (see Berggren, Kent, and Flynn, 1983), the COSUNA charts use the time scale proposed by the COSUNA Geochronology Committee (Salvador, 1981). Use of a single time scale for all charts facilitates both correlations between regions and \"'ith updated time scales.

-3- 2. The absolute time scale of this chart changes at 1, 5,and 25 million years to conform with the California COSUNA Chart allowing for format uniformity between the two West Coast charts.

3. The Oregon and Washington Chronostratigraphic Units are correlated to the Global and Oceanic Chronostratigraphic Units by specialists in each discipline and are in general agreement with the California COSUNA Chart.

NOTE: To this point, all correlations are by committee and are thus a 'compromise' to attain uniformity between all charts or at least charts of adjacent areas.

4. Correlation of the western Oregon and Washington Cenozoic strati graphic units is based on the recommendations of local authorities using biostratigraphic data and superpositional relationships.

5. Radiometric data are noted only on the formation data sheets. Some of the radiometric ages are not compatible with biostratigraphically derived million-year ages. Because the Global Chronostratigraphic Units are based on biostratigraphically defined units, correlations to that time scale must be biostratigraphic ( see Berggren, 1981). Resolution of discrepancies between biostratigraphically and radio netrically derived million-year ages requires further research.

6. The western Oregon and Washington Cenozoic COSUNA Chart represents a statement of knowledge by the contributing authors as of �1arch 18, 1983.
