Phytoliths as quantitative indicators for the reconstruction of past environmental conditions in China I
Evolution of megadunes and lakes in the Badain Jaran Desert, Inner Mongolia, China during the last 31,000 years
Glacial environments on the Tibetan Plateau and global cooling
The ‘Mediaeval Warm Period’ drought recorded in Lake Huguangyan, tropical South China
The geochemistry of dated sediment cores from Lake Huguangyan (21°9′N, 110°17′E), tropical South China, reveals distinct stratigraphical patterns in total organic and inorganic carbon (TOC, TIC), biogenic silica (BS) and total nitrogen (TN) over the past 1400 years. In this hydrologically closed lake, TIC variations may re‘ ect changes in the precipitation/evaporation ratio, which controls the evaporative enrichment of carbonate. TOC, BS and TN i…
Distribution of 14 C and 13 C in Forest Soils of the Dinghushan Biosphere Reserve
We report here first results on the bulk soil organic carbon (SOC), apparent radiocarbon ages and δ 13 C characteristics of the tropical and subtropical forest soil in Dinghushan Biosphere Reserve (DHSBR). The forest oxisol in Dinghushan has developed during the Holocene. The δ 13 C variation curves in all three profiles may be divided into two sections. The upper section from 0 to 40 cm has δ 13 C values varying from −27.4 to −24.1‰, −27.5 to −2…
Stratigraphic Evidence for the Uplift of the Tibetan Plateau between ∼1.1 and ∼0.9 myr Ago
Uplift of the Tibetan Plateau is manifest not only in widespread denudation, but also by an increased deposition rate of sediment, near or far from the exhumed regions. Our results indicate that the mass accumulation rate (MAR) of eolian dust increased between ∼1.1 and ∼0.9 myr ago. We associate this increase in MAR and median grain size with uplift of the Tibetan Plateau and its adjacent regions during this period. This Middle Pleistocene uplift…
Changes in Sand Content of Loess Deposits along a North–South Transect of the Chinese Loess Plateau and the Implications for Desert Variations
Geological records have shown that the deserts east of the Helan Mountains in northern China were covered by grass during the Holocene Optimum, whereas during marine oxygen isotope stages 2 and 4 distribution of the deserts was almost the same as at present. The wide advance–retreat cycles of the deserts may have exerted an important control on grain-size changes in the loess of the Loess Plateau by altering the distance between the source and th…
Spectral analysis of a 1000-year stalagmite lamina-thickness record from Shihua Cavern, Beijing, China, and its climatic significance
Stalagmite laminae provide a high-resolution geological record of climate change. In this paper, moving spectral analysis is used to analyse a stalagmite lamina thickness record to study climatic variability. It was found that the dominant cycles of the lamina thickness sequence are 2, 3.3, 5–6, 10–12, 14–18, 133 and 194 years. Some of the cycles are the same as the cycles of modern climatic indices, such as the QBO (Quasi Biennial Oscillation) o…
Chinese Loess and the Paleomonsoon
This paper presents a general review of the recent research advances of the East Asian paleomonsoon, based mainly on studies of the loess-soil sequences in the Chinese Loess Plateau. In the last 2.6 million years, the paleomonsoonal history may be divided into about 166 events on a time scale of the Earth's orbital variations. During the last glacial period, millenial-scale oscillations of the monsoon system were prominent, which can be fairly we…
Biogenic Silica Record in Lake Biwa of Central Japan over the Past 145,000 Years
The record of the biogenic silica flux (BSF, g cm −2 (10 3 yr) −1 ) in Lake Biwa reflects changes in diatom productivity in the lake and provides information regarding changes in paleoclimatic conditions. The BSF record of Lake Biwa demonstrates five periods over the past ca. 145,000 yr when the BSF values were significantly greater than 7.5 g cm −2 (10 3 yr) −1 , and five intervals when they were lower. The data imply that paleoclimatic conditio…
Eolian Quartz Flux to Lake Biwa, Central Japan, over the Past 145,000 Years
Eolian quartz flux (EQF, g cm −2 (10 3 yr) −1 ) to Lake Biwa, central Japan, provides direct information on variations of the East Asian winter monsoon. Lake Biwa sediments spanning the past ca. 145,000 yr are characterized by two main periods when EQF values were significantly greater than 5.50 g cm −2 (10 3 yr) −1 , and two main intervals during which EQF values were lower. Two periods with EQF values >5.50 g cm −2 (10 3 yr) −1 occurred from ca…
Stable isotope composition of the carbonate concretion in loess and climate change
The onset of extensive loess deposition around the G/M boundary in China and its palaeoclimatic implications
C Dating of Terrestrial Moss in Tern Lake Deposits, Antarctica
Accurate radiocarbon ages were obtained from terrestrial moss from two drill holes in Tern Lake deposits, Antarctica, using liquid scintillation counting (LSC) and accelerator mass spectrometry (AMS). The results show that the lake deposits have been accumulating since the end of the last glacial epoch ca. 12,600 cal BP at the rate of 0.13–1.1 mm a -1 . We discuss the validity of 14 C ages of Antarctic lake deposits, with respect to the latitude …
Ice-Volume Forcing of East Asian Winter Monsoon Variations in the Past 800,000 Years
Particle-size measurements of some typical loess-soil samples taken in different localities of the Chinese Loess Plateau demonstrate that the grain size ratio of 10 μm (%) can be used as an indicator of variations in intensity of the East Asian winter monsoon winds. Grain-size curves of the Baoji and Weinan sections show that this proxy indicator is very sensitive to loess-soil alterations. Analytical results also suggest that during soil-forming…
Remanence Characteristics of Different Magnetic Grain Size Categories at Xifeng, Central Chinese Loess Plateau
Utilizing the thermal unblocking of low-temperature remanent magnetization in superparamagnetic (SP) ferrimagnets and the low-temperature demagnetization of multidomain (MD) magnetite remanences, the relative proportions of SP, MD, and singledomain (SD and SD-like) ferrimagnets are estimated in the topmost part of a loess section at Xifeng, China, which covers about the past 130,000 yr. SP ferrimagnets are commonly regarded as pedogenic (authigen…
