The upper part of the Karamaydan section, Tadjikistan, shows the most detailed loess-paleosol sequence yet known for the Brunhes chron, and the central and lower parts of the Chashmanigar section provide similar detail for most of the Matuyama chron
Mesure des propriétés paléomagnétiques de 357 échantillons encore gelés, provenant de 2 longs forages avec carottage (Taglu, Kumak), dans le delta de la rivière Mackenzie. Identification des chrons majeurs et des sous-chrons d'Olduvai et de
Here the AA. report paleomagnetic data from independently dated loess in New Zealand which spans the last ca. 500,000 years, entirely within the Brunhes Normal Chron. This is the longest continuous sequence described to date and these paleomagnetic
A succession of sediments and paleosols near Dreihausen records a normal magnetic remanence throughout and appears to have formed during the Bruhnes Chron. The paleosols contain argillic horizons which formed largely during interglacial periods when
The polarity reversal patterns, together with earlier vertebrate paleontologic studies, restrict the time span for deposition of the Palm Spring Formation to the middle-late Matuyama chron (2.0-0.75 myr ago). Characteristic directions of least
and the presence of underlying middle Pliocene dated basalts, indicate that the Portland section, was deposited within the late Matuyama Chron between 1.66 and 0.73 myr ago. In addition, the reversed polarity for the Bridgewater Formation confirms the previous
A micromorphological comparison of the loess-paleosol sequence of the Karamaydan section, Central Asia, with the upper part of the Luochuan section, China, clearly indicates that for the Brunhes chron the sequence at Karamaydan is more detailed than
The AA. present evidence that indicates a limited advance of alpine glaciers occured in the Colorado Front Range Mountains during the Younger Dryas Chron. Sky Pond was selected for this study because it is situated directly downvalley from a moraine
Initial interpretation of the sediments from the Burmester core indicated that 17 deep-lake cycles, separated by shallow-lake and soil-forming intervals, occurred in the Bonneville basin during Brunhes Chron (the last 780 000 yr). The re-examination
This work sets out a detailed, orbitally tuned biogenic silica record of Lake Baikal for the entire Bruhnes chron, discusses the fine structure of interglacial stages and related abrupt climatic events, and presents a new hypothesis about
of a climate model based on glacial maximum conditions. There is no compelling evidence for a climatic reversal corresponding to the European Younger Dryas chron. During the early Holocene there may have been years when winds were insufficiently strong
identified as the main carriers for the characteristic remanent magnetizations. Magnetostratigraphic results show that the lacustrine sequence recorded the late Matuyama and Brunhes chrons. The results suggest an expansion and lengthy flourishing of human
The retreat record of the Stabre Glacier into the Norra Storfjället mountains, after separation from the massive Tärnaån Glacier at some undetermined time in the Atlantic Chron, is documented by recessional moraines in the foreland. While poorly
of Praetiglian, is estimated at approximately 2 million yr by paleomagnetic dating. The major cold-warm climatic cycles of the earliest Pleistocene lasted approximately 100,000 yr, the same as those of the Brunhes Chron. The intervening Main Terrace systems has
