Pedogenically degenerated illite and chlorite lattices aid to palaeoclimatic reconstruction for chronologically constrained(8-130 ka) loess-palaeosols of Dilpur Formation,Kashmir,India
《Geoscience Frontiers》2020年第4期1353-1367,共15页Meenakshi J.P.Shrivastava Rakesh Chandra 
We acknowledge the Project Grant(IUAC-AUC No.60323)in the form of Fellowship(to Meenakshi)provided by the Inter University Accelerator Centre(IUAC),New Delhi.Mr.Vijay Rajpal,Department of Geology,University of Delhi is acknowledged for the XRD analysis.
Chronologically well-constrained loess-palaeosols(recorded glacial and inter-glacial climate) revealed pedogenesis induced ionic substitutions,caused end-member compositional deviations in illite and chlorite,linked t...

This work was supported by the National Natural Science Foundation of China （Grant Nos. 41272053 and 41472041）. C.W. acknowledges a postdoctoral science foundation of China （2015M582301）, Fundamental Research Funds for the Central Universities, China University of Geosciences （Wuhan）, and National Natural Science Youth Foundation of China （Grant No. 41602037）. The authors wish to thank Dr. Yu J. S. for XRD analysis, Dr. Liu X. W, for HRTEM analysis and Dr. Yang H. and Dr. Yang Q. for SEM analysis.
To understand climate changes recorded in the Luochuan loess-palaeosols, Shaanxi province, northwes- tern China, clay mineralogy was studied using X-ray diffraction （XRD）, high-resolution transmission electron micro...

Flood basalt hosted palaeosols:Potential palaeoclimatic indicators of global climate change
《Geoscience Frontiers》2014年第6期791-799,共9页M.R.G.Sayyed 
Since continental sediments （in addition to the marine geological record） offer important means of deciphering environmental changes, the sediments hosted by the successive flows of the continental flood basalt prov...

Red Palaeosols Development in Response to the Enhanced East Asia Summer Monsoon since the Mid-Pleistocene in South China: Evidence Derived from Magnetic Properties and Molecular Fossil Records被引量：5
《Journal of Earth Science》2013年第3期382-396,共15页顾延生 黄咸雨 张卫国 洪汉烈 李永涛 
supported by the National Natural Science Foundation of China(Nos.40502015,40872202,and40930210);the 111 Project of China(No.B08030)
Although Pleistocene red paleosols are widely distributed in South China, paleoenviron-mental interpretation has proved difficult because of intense weathering. Here we combine data from molecular fossil and magnetic ...

Origin of Red Color of the Lower Siwalik Palaeosols:A Micromorphological Approach被引量：2
《Journal of Mountain Science》2009年第2期147-154,共8页Seema Singh B.Parkash Arun.K.Awasthi 
Palaeosols associated with fluvial of the Siwalik Group are and lacustrine deposits that occur as thick multiple pedocomplexes. The bright red color of the palaeosol beds has been earlier interpreted as a result of ho...

Biomorphic analysis as a basis for paleoenvironmental reconstruction
《Chinese Science Bulletin》1999年第S1期139-144,共6页Alexandra GOLYEVA 
A definition for biomorphic analysis is suggested. The objects of analysis - biomorphs(phytoliths, sponge spicules) - are characterized with respect to their diagnostic features andmethods of data interpretation. The ...

Aspects of palaeosols in Australia
《Chinese Science Bulletin》1999年第S1期26-29,共4页Clifford David OLLIER 
Numerous examples of long term landscape are presented relating soil and regolith tolandforms going back to Cenozoic or Mesozoic times. Many conventional approaches to soil areinappropriate for such materials. It is i...
