Sediment magnetic, paleomagnetic and geochemical results have beenobtained from lacustrine sediments recovered in a 30-meter coretaken by rotary drilling methods at Grass Lake, Siskiyou County,California. The data have been analyzed and interpreted in termsof environmental change in the Grass Lake catchment over the pastca. 100,000 years.
Sediment Magnetic and Geochemical Data from Quaternary Lacustrine Sediment in Two Cores from Tule Lake, Siskiyou County, California
Sediment magnetic and geochemical results have been obtained fromthe top 60 meters of lacustrine sediments recovered in two coresfrom Tule Lake in northern California. The sediment magnetic andgeochemical data, presented here in tabular form, complementstudies of diatoms and pollen in the cores that are the bases forpublished paleoclimatic interpretations. This report alsodocuments the methods used to obtain the magnetic properties andgeochemical data.
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Gravity and aeromagnetic surveying and modeling lines
Lines in this cover show where gravity oe aeromagnetic data have beenmodelled to constrain subsurface structure. Gravity andmagnetic signatures result from deep structure, such as might be athypocentral depths of earthquakes. We show only the lines for whichinterpretations or models are publically available. In gravmag_all,extent of the lines outside the study boundary is retained;in gravmag the lines have been clipped to the study boundary.
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Magnetotelluric sounding points and modelling lines
Magnetotelluric soundings give data that can help define the lelectricamagnetic properties of rocks, and with othergeophysical data help define thestructure of the shallow crust where earthquakes occur. The soundingpoints in this cover show where data was collected that was thenmodelled for deep structure (see reference).
Sediment magnetic and paleomagnetic studies were conducted on a core fromBuck Lake, Klamath County, Oregon, that was collected as part of aninvestigation into the Quaternary climate history of the western UnitedStates. This report documents the methods used to obtain paleomagneticdirections, magnetic properties, and ancillary data, and presents thesedata in tabular form.
