Through the studying of heavy mineral assemblages and ZTR index variation features, this paper analyses the provenances and sedimentary systems of Saertu reservoir in Cretaceous of Jiangqiao-Pingyang area, western slope zone in northern of Songliao basin. It is concluded that there are three major sedimentary systems in the Saertu reservoir depositional period, named the Nehe-Yian sedimentary system in Northeast, Yingtai sedimentary system in Southwest, Qiqihaer sedimentary system in Northwest. The intensity and influence scope of the sedimentary systems in sedimentary period of SaII+III, SaIand Sa 0 reservoir changed. During the sedimentary period of SaII+III reservoir, research area is mainly controlled by the Qiqihaer and Yingtai sedimentary systems, the control action of Nehe-Yian sedimentary system in the research area is faint. During the sedimentary period of SaIreservoir, Nehe-Yian sedimentary system control the sedimentation of mainly region in research area, the control range of Qiqihaer sedimentary system has shrunk to the West of Jiangqiao area, the Yingtai sedimentary system dropped out of the research area. During the sedimentary period of Sa 0 reservoir, the control action of each sedimentary system basically inherited the distribution pattern of the sedimentary period of SaIreservoir, but the source supply capacity weakened further.

Northern Honggang Area is situated in the north of Daan-Honggang terraces, southern Songliao Basin, bounded on the west of the western slope, on the northeast by Cologne sag, and on the southeast by Changling sag. The facies types of Northern Honggang District are mainly delta. The upper part of Fuyu oil layer is dominated by delta-front facies, the lower part is dominated by delta-plain facies.

AbstractThis study considers the Upper Cretaceous Qingshankou Formation, Yaojia Formation, and the first member of the Nenjiang Formation in the Western Slope of the northern Songliao Basin. Dark mudstone with high abundances of organic matter of Gulong and Qijia sags are considered to be significant source rocks in the study area. To evaluate their development characteristics, differences and effectiveness, geochemical parameters are analyzed. One-dimensional basin modeling and hydrocarbon evolution are also applied to discuss the effectiveness of source rocks. Through the biomarker characteristics, the source–source, oil–oil, and oil–source correlations are assessed and the sources of crude oils in different rock units are determined. Based on the results, Gulong and Qijia source rocks have different organic matter primarily detrived from mixed sources and plankton, respectively. Gulong source rock has higher thermal evolution degree than Qijia source rock. The biomarker parameters of the source rocks are compared with 31 crude oil samples. The studied crude oils can be divided into two groups. The oil–source correlations show that group I oils from Qing II–III, Yao I, and Yao II–III members were probably derived from Gulong source rock and that only group II oils from Nen I member were derived from Qijia source rock.

Kyriaki, c. 100 m. from the point where the road crosses the watershed into the catchment area. The terrace is c. 150 m. (N.-S.) by 50 m. (E.-W.), bounded on the east by steep, bare upward gradients, and on the west by a steep downward slope covered only with low scrub. Two possible stretches of wall were found on the western slope, but the only certain structural remains were a modern sheep pen and a circular wall, c. 1–5 m. in diameter, which appeared to be a filled-in well. Abraded sherds were quite common on the western slope, but scarcer on the terrace.

Spaces are conditioned by social conditions; on the other hand, social structure is affected by spaces. Arcades, the subject of this article, first appeared in Europe in the 18th century as a result of an increase in trading activities. The arcades in Ankara, which were started to be built in the 1950s together with increasing trading activities, contributed to the urban economy with intense activities of shopping, re-determined social and urban relations as essential places of everyday life and became distinctive urban buildings with their original building typologies and the function of maintaining public continuity in the area of private ownership. Aim: This study aims to study the process in which passages emerged and to analyze their spatial features and, in particular, to examine the spatial formation of the distinctive passages in Ankara on the basis of their causation. Method: In the article, spatial features of the passages in the West were mentioned, and the conditions of the period in which the passages in Ankara were built were briefly explained. Spatial analysis of the passages found in the research area were conducted, and the formation of these passages were analyzed together with their reasons. Results: Of the 31 arcades in Ankara, 27 were built between 1950 and 1980 on and around the Atatürk Boulevard in Yenişehir/Kizilay. As of the mid-1950s, new planning decisions which were made one after the other in the built-up area re-shaped the Boulevard and its surrounding as the existing buildings were demolished, allowing to construct new buildings with arcades or stores in their entrances. Their interior designs and connections to the streets are different from the arcades in the West. Conclusion: The present subdivision system and new planning decisions applied in property order shaped the passages which were peculiar to Ankara.

Mineral Assemblages

As stated previously the aim of this paper is chiefly to call attention to the differences between the mineral assemblages of the Downtonian, Dittonian, and Farlow Sandstone beds of the Old Red Sandstone, particularly when the percentages of the different mineral grains are obtained by accurate counting. Further work will show how far these investigations may be correlated with the examination of the rocks in adjacent districts, and the author suggests that a similar calculation of percentage figures on the minerals of such deposits may assist in indicating more definitely the sources from which they have been derived.

Climate change leads to the increase of frequency and intensity for extreme precipitation events, potentially threatening the development of our society. It is of great significance to study the spatiotemporal variation of precipitation for understanding cycle process of water and its response to global warming. This paper selects the Xijiang River basin, which locates on a low latitude and coastland, as the research area. The spatiotemporal distribution and homogeneity of precipitation are analyzed, and the spatial trend is studied using 12 extreme precipitation indices. Finally, chaotic characteristics are evaluated for daily precipitation. The results showed that the precipitation in the basin tended to be unevenly distributed. On wet days, precipitation in the middle and the west was more and more uniform. The proportion of tiny rain was the largest, between 33.5% and 41.3%. The proportion of violent rain was the smallest, between 0.1% and 4.7%. Duan had the highest frequency for violent rain, and the probability of disasters caused by extreme precipitation near the station was the highest. The simple daily intensity index (SDII) showed a significant increase in the middle and the northeast. PRCPTOT (annual total wet-day precipitation) showed a decreasing trend in the northwest. The average rates of variation for R95PTOT (precipitation on very wet days) and R99PTOT (precipitation on extremely wet days) were −0.01 mm/year and 0.06 mm/year, respectively. There might be a risk of drought on the west of the basin in the future. Precipitation in other locations was still relatively abundant. Daily precipitation showed high dimension and high chaotic characteristics. The MED (minimum embedding dimension) was between 11 and 30, and the MLE (largest Lyapunov exponent) was between 0.037 and 0.144.

This research is a hydrogeological survey activity with the aim to determine the geological characteristics of groundwater in the Hargorejo area, Kokap Sub-district, West Progo. The study wants to know about the pattern of groundwater flow and water quality in the area. The northern part of the research area is included in the non-groundwater basin region of the West Progo Dome, while the southern part is included in Wates Groundwater Basin. Method of research is a field hydrogeological survey, to obtain geological and groundwater data. Groundwater flow pattern and quality analyses are based on groundwater data and pH, TDS and EC values. Groundwater can be obtained from springs or dug wells, with relatively shallow groundwater tables. The pattern of groundwater flow is generally to the south, with the H4 / H5 basin boundary type. Groundwater quality is quite good, with a pH value of 6.2 -7; TDS 191 - 558 ppm, and EC ranges from 279-783 µS / cm.
