Surface snow samples were collected during the 14th(1997/1998)and 24th(2007/2008)chinese National Antarctica Research Expeditions along a transect from Zhongshan Station to Dome *** stable oxygen isotope ratios of these samples were measured to investigate their relationships with temperature and geographical parameters(latitude,longitude,altitude and distance to the coast).The results reveal a strong positive correlation(R=0.945)betweenδO and mean annual temperature,with a gradient of 0.84‰℃,which is a little higher than that in Terre Adelie *** analyses also show that theδO of surface snow is strongly correlated with distance to the coast(R=0.942),latitude(R=0.942),and altitude(R=0.941).But no significant correlation was found betweenδO and longitude in study *** should be the most important factor influencing theδO distribution because of distinctive ***δO-altitude and T-altitude gradients along this transect are determined to be-1.1‰/100 m and 1.3.℃/100 m,respectively.

A sample from the top of the Banxi Group(early Neoproterozoic) in Hunan Province(South china) was dated by the SHRIMP zircon U-Pb *** resulting age of 725±10 Ma probably solves the debate between the synglacial and the pregkcial correlation of the Liantuo Formation and indicates that the Liantuo Formation most likely correlates with the pregkcial Banxi *** the Banxi(Danzhou) Group is upwardly transitional to the glacial Jiangkou Group,the age becomes a new maximum age constraint on the onset of the Jiangkou glaciation,which therefore most likely correlates with the Sturtian glaciation.

The Jiaodong super-large gold metallogenic region is located on the eastern margin of the North china craton and the western margin of the Circum-Pacific tectonic ***-forming chronology indicates that these deposits formed at 120±10 *** and argon isotope compositions of fluid inclusions in pyrite range in He/He ratios from 0.3. to 2.3. R/Ra(R:He/He ratios of samples;Ra:He/He ratios of beijing air,1.4×10) and in Ar/Ar ratios from 3.0 to 1148.δ0 andδD values of fluid inclusions in quartz are—2.16 to +6.28‰and—65 to—98‰,respectively.A consistent relationship between H-O and He-Ar isotopic systems show that mantle-source fluids were involved in large-scale metallogeny in the Jiaodong *** fluids were produced accompanying delamination,lithosphere thinning,and crust-mantle interaction that occurred in the eastern North china craton during the Early Cretaceous(140—120 Ma).

The composition of single-grain detrital zircons is an effective provenance indicator of loess,and sheds new light on dust formation and *** we review the features of detrital zircons and their use as a provenance indicator,including internal structure,trace element,U-Pb age spectrum and Hf isotopic compositions,and present a case study from the Horqin sandy land and its surrounding *** loess samples have detrital zircon age peaks in range of 2600-23.0,2100-1600,and 600-100 Ma,of which the 2600-23.0 Ma zircon grains mainly have positive Hf(t) values(3.4-8.7),the 2100-1600 Ma zircon grains mainly have negative Hf(t) values(10.1-6.8),and the 600-100 Ma zircon grains have a variable Hf(t) values ranging from 21 to *** detrital zircon signatures of the loess are similar to the Horqin sandy land,but clearly different from the chinese Loess Plateau and central-western deserts,implying that the loess is transported mainly from the Horqin sandy land in the Last Glacial *** these with neighboring tectonic units,we found that zircon populations at 2600-23.0,2100-1600,and 600-100 Ma with negative Hf(t) values may come from the northeast North{3. Craton(NCC),and those at 600-100 Ma with positive Hf(t) values may come from the east Central Asian Orogenic Belt(CAOB).It is estimated that the two sources contribute equally to the Horqin sandy land and the surrounding loess.

We develop a separable-kernel decomposition method for approximating the double-square-root(DSR) continuation operator in one-way migrations in this *** new approach is a further development of separable approximations of the single-square-root(SSR) *** separable approximation of the DSR operator generally involves solving a complicated nonlinear system of integral *** of solving this nonlinear system directly,our new method consists of repeatedly applying the separable-kernel technique developed for the two-variable SSR operator to the multivariable DSR *** experiments demonstrate the efficiency of the proposed *** illustrate the fast convergence of the obtained separable approximation. We also demonstrate the capability of this novel approximation for imaging an area with geologic complexities through synthetic data.
