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 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.
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.
