Sedimentation, stratigraphy and facies variation of the lower to middle Miocene Astoria Formation in Oregon

Creator:: Cooper, David Michael
Resource Type:: Masters Thesis

Stratigraphy and sedimentary petrology of the Mascall Formation, eastern Oregon

Creator:: Kuiper, John L.
Abstract:: The type section of the Mascall Formation, which is located in the John Day Valley, is interpreted to represent a sequence of paleosols. These fossil soils were formed on a floodplain during the middle Miocene. The measured thickness of this section is 1340 feet, and although the top of the...

Extension and volcanism : tectonic development of the northwestern margin of the Basin and Range Province in southern Oregon

Creator:: Scarberry, Kaleb C.
Abstract:: The northwestern corner of the Basin and Range Province (NWBR) lies in southeast Oregon where extensive Late Miocene, mafic to bimodal basalt-rhyolite volcanism and extensional faults dominate a stark and arid landscape. Near Lake Abert, the Late Miocene volcanic section abuts Early Miocene, dominantly intermediate composition volcanoes at the Coleman...

Creator:: Oregon. Dept. of Geology and Mineral Industries, Snavely, Parke Detweiler, 1919-, MacLeod, Norman S., Rau, Weldon W., and Geological Society of America. Cordilleran Section. Meeting (65th : 1969 : Eugene, Or.)
Abstract:: This field trip consists of two geologic tours. On Tour 1, the Tertiary sedimentary rocks exposed along the Yaquina River between Newport and Toledo, Oregon, will be examined. This tour will start at the mouth of Yaquina Bay where Miocene sedimentary rocks are exposed and will proceed generally eastward and...

Two-stage opening of the northwestern basin and range in eastern Oregon : evidence from the Miocene Crane basin

Creator:: Milliard, Justin B.
Abstract:: New data are presented that provide evidence for the onset of extensional deformation in the Northwestern Basin and Range within 1 million years after the eruption of the Steens Basalt at 16.5 Ma. New geologic mapping (1:24,000), stratigraphic sections, and ⁴⁰Ar/³⁹Ar dating of the Crane Basin rocks provide a control...

The oligocene and miocene geology of the Tillamook embayment Tillamook County, northwest Oregon

Creator:: Parker, Michael J. (Michael John), 1958-
Abstract:: Eleven sedimentary and volcanic rock units are mapped and described in the thesis area, and chronicle the dynamic geologic history of the Tillamook embayment from the Oligocene through the middle Mlocene. The oldest unit is the Zemorrian to early Saucesian Smuggler Cove formation, a bathyal tuffaceous mudstone with some thin-...

Snow Peak, OR: late Miocene to early Pliocene volcanism in the central Cascadia forearc

Creator:: Hatfield, Ashley K.
Abstract:: Snow Peak is a voluminous shield volcano located ~50 km west of the axis of the modern Cascade arc. A previously published K-Ar age estimate indicates that the Snow Peak lavas are ~3 Ma. Subsequently, the preliminary research framework for studying the Snow Peak lavas focused on constraining the petrogenesis...
