Geothermal History of Hydrocarbon Generation of Wells in the North Western Desert, Egypt

The Huanghua Depression is located in the north-centre of Bohai Bay Basin, which is a rift basin developed in the Mesozoic over the basement of the Huabei Platform, China. Permo-Carboniferous source rocks were formed in the Huanghua Depression, which has experienced multiple complicated tectonic alterations with inhomogeneous uplift, deformation, buried depth and magma effect. As a result, the hydrocarbon generation evolution of Permo-Carboniferous source rocks was characterized by discontinuity and grading. On the basis of a detailed study on tectonic-burial history, the paper worked on the burial history, heating history and hydrocarbon generation history of Permo-Carboniferous source rocks in the Huanghua Depression combined with apatite fission track testing and fluid inclusion analyses using the EASY% Ro numerical simulation. The results revealed that their maturity evolved in stages with multiple hydrocarbon generations. In this paper, we clarified the tectonic episode, the strength of hydrocarbon generation and the time–spatial distribution of hydrocarbon regeneration. Finally, an important conclusion was made that the hydrocarbon regeneration of Permo-Carboniferous source rocks occurred in the Late Cenozoic and the subordinate depressions were brought forward as advantage zones for the depth exploration of Permo-Carboniferous oil and gas in the middle-northern part of the Huanghua Depression, Bohai Bay Basin, China.

The Ixil Maya area is located in Quiche Department of the north-western part of the Guatemalan Highlands. It has witnessed a continuous occupation since the 1st millennium BC till today. This archaeologically interesting region has provided many important discoveries of rare cultural mixture, with distinct features typical for both Maya Highlands and more distant Lowlands. Recently, the scholarly interest has focused on Chajul where a few years ago, in one of the local houses, well preserved wall paintings dated to the Colonial period were exposed by the house owner during the process of its renovation. With this extraordinary finding a question emerged - are we able to confirm the cultural continuity between the pre-Columbian settlers and modem Ixil who claim «to be always here»? This paper presents a brief outline of the history of the Ixil Maya. It also presents results of some recent and preliminary studies conducted by Polish scholars in this region.

Descriptive Method

Introduction. History of the North-West area of Novgorod land at the end of the XV century attracted the attention of researchers mainly in the socio-economic aspect. This is due to the fact that Novgorod scribal books are dated by the end of the XV century. From the standpoint of socio-economic history their value is not in doubt, but from an ethno-historical point their onomastic content is underestimated. Materials and methods. The main source of research was the scribe book of the Vodskaya Pyatina 1499/1500. The descriptive method of research is to identify and record the Baltic-Finnish oikonyms (names of rural settlements) and anthroponyms mentioned in the scribe books. Baltic-Finnish anthroponyms are identified on the basis of an analysis of formal indicators of borrowing the anthroponyms. Results and Discussion. There are several areas where the Baltic-Finnish oikonymy and anthroponymy were concentrated, namely Korboselsky graveyard in the northern Prinevye, Lopsky and Terebuzhsky graveyards in the southern Ladoga, as well as Dudorovsky and Izhora graveyards south of the Neva. Archaeological sources record a significant presence of the Izhora antiquities. The presence of Karelians is noted in the northern Prievye and southern Ladoga. Slavic onomastic materials are recorded throughout Orekhovsky and Ladoga counties, but to mostly in the cities of Oreshka, Ladoga and their nearest areas. Conclusion. By the end of the XV century the north-western graveyards of Novgorod land were inhabited by representatives of various ethnic groups: Slavs, Vodians, Izhora and Karelians, as evidenced by the data of anthroponyms and toponyms of the scribe’s books and confirmed by archaeological sources.
