Ginkgo from Lower Cretaceous Changcai Formation in Helong of Jilin, NE China

Based on gross morphological and cuticular study, two species of Ginkgo From the Lower Cretaceous Changcai Formation in Helong of Jilin. were identified from this area for the first time, including Ginkgo coriacea Florin and G.sibiricaHeer. The study is significant for better understanding the paleophytogeographic, paleoecologicandstratigraphic characters of the Early Cretaceous Changcai flora.

Treatment effect investigation of underground continuous impervious curtain application in water-rich strata

Serious shaft lining failures often occur when shaft linings are constructed by passing them through the deep topsoil of Quaternary strata. This approach also leads to the formation of an aquifer at the bottom.Based on the theory of the additional stress which is the main reason for these failures, this study focuses on the treatment effect of underground continuous impervious curtain(UCIC) in terms of different factors, namely, the location, shape, range, and width, by using numerical simulation. Results show that the UCIC can reduce the stress concentration in the shaft lining formed in the bottom aquifer. The UCIC can also reinforce the shaft lining at different angles and can be applied in actual situations. The strength factors of the inner surface of the shaft lining increase after the UCIC are used. The material strength and width of the UCIC show an obvious effect on the stability of the shaft lining. Results proved that the UCIC could effectively strengthen the stability of the shaft lining when it was built in the aquifer or built in the aquifer and above and below the layer.

Investigation on influence factors of dual laterologs curve form

In order to investigate the influences of caliper, formation thickness and invaded zone on the form of dual laterologs, forward modeling technique were applied to calculate the dual laterologs for different cases. The result shows that the resistivity logs become smoother and lower as the borehole diameter increases, the increase of the contrast between mud resistivity and formation resistivity induce the logs to be more pointed. When the formation thickness is less than lm, the two-peak on the logs for resistive invasion vanished, and for thickness between 1 m and 4 m, the form of logs does not vary significantly. If the formation thickness is greater than 4 m, a platform appears on the logs at the middle of the formation. The thinner the invaded zone is, the more obvious the invasion feature on the laterologs is. For thick invaded zone the form of logs tend to be that of an uninvaded resistive formation. The form and amplitude of logs depend on the resistivity contrast between invaded zone, uninvaded formation and adjacentlayers.

A "Yellow Cap" on Quaternary Red Clay in Jiujiang,Jiangxi Province

A thin layer of yellow-brown-colored earth was generally found on Quaternary red clay in Jiujiang,Jiangxi Province. A typical profile was established. Both particle size distribution and REE (rare earthelements) characteristics of the yellow-brown-colored earth of the profile fully suggested its aeolian origin andclose similarity to Naming Xiashu loess. The study also implied aeolian origin of the underlying Quaternaryred clap Compared with the red clay, the yellow- brown- colored earth was less weathered because of its lowercontent of free iron and higher mole ratios of SiO2/A12O3 and SiO2/(Fe2O3+A12O3 ) as well as its lessdeveloped chemical microtextures of quartz grains.In order to study the aged of the two deposits comparatively, the thermoluminescent dating method wasused. As a result, the bottom of the yellow-brown-colored esrth was dated to 6015 ka B. P. and the upperpart of the red clay 38854 ka B. P. It was suggested that the yellow- browm- colored earth was formed inthe Late Pleistocene and was probably the aeolian deposit of the Last Glacial, which corresponded with theMalan loess in the Loess Plateau of the northwestern part of China; while the underlying red clay was formedin the Middle Pleistocene.A "yellow cap" on Quaternary red clay in Jiujiang implied a great climatic and environmental varistionin the beginning of the Late Pleistocene in the southern pot of China, especially in the middle and lowerreaches of the Yangtze River. The eveal not only halted the rubification, once dominating the region, butalso produced a widespread covering of aeolian deposit, as only occurred in the cold and dry environment.

Recent Age Sediments and Soils of the Kish Island, Persian Gulf： Origin and Characters

Kish Island is elliptical-shaped with 7 km width, 15.6 km length and 89.7 km2 space, located in the Persian Gulf, south of Iran. There are many tourism potentials. In order to better know and evaluate the recent sediments and soils of this island, field studies are done. One hundred samples are taken and subjected to geology and pedology examinations. The whole surface of the studied area is covered by Quaternary deposits. The rock units of these deposits are formed with reef limestone and little gypsum marl. Recent sediments and soils of Kish Island with very little thickness are exposed to marine currents, such as wave, tide and wind and temporary runoffs on reef limestone, which are formed approximately 11,000 years ago. In addition of carbonate deposit, there are few amounts of clay minerals, gypsum and halite that are present in the combination of fine grain to coarse grain. The soils of this island are categorized in 23 series and four classes. The soil has low fertility.

Characterization of Organic Matter Preserved in the Triassic Lockatong Formation in the Newark Basin

This study is aimed at characterizing the organic matter preserved in the Triassic Lockatong formation deposited in the Newark Basin. On the basis of the TOC （Total Organic Carbon）, the Lockatong formation was deposited in a reducing environment in the deep NW part of the basin, which is favorable to the accumulation of organic matter. However, the Lockatong formation of the SE border of the basin was deposited in oxic conditions that prevented the preservation of organic matter if there is any. The structuration of the basin into deep subsiding NW section due to the reactivation of the NE-SW striking faults and the development of anoxic conditions were favorable for the accumulation and preservation of the organic matter in the deep part of the basin.
