藏北措勤盆地白垩纪碳酸盐岩沉积相及缺氧事件响应研究

As a part of Gangdisi-Nianqingtanggula plate, Cuoqin basin (N 29°3O'～33°20'; E 80°～90°) is situated in the west of the Tibet autonomous Region, with an area of 100000 square kilometers. Cretaceous shallow-water carbonate is widely distributed in this basin. Its accumulative thickness is more than 1000 meters. Sedimentary facies of cretaceous shallow-water carbonate and carbon isotope feature are studied in details here. On basis of two main sections researched comprehensively, five facies marks are found. With the combination of Wilson's model and ramp model, a platform-mild slope model are put forward, which is thought to be a comprehensive model for this area. There are three sedimentary circles which are comprised of terrestrial clastic tidal flat and carbonate platform facies in Duoba Member of Duoni Formation. Langshan Formation is mainly comprised of carbonate platform facies. We also studied the carbon isotope features influenced by Cretaceous Aptian-Albian's oceanic anoxic events (OAE). After correlating the δ~(13)C curves of the studied section with that of Peregrina Canyon section in Mexico, we find that there are similar δ~(13)C curves fluctuation styles, namely there is also a δ~(13)C positive excursion in shallow-water carbonate in the studied area, and the degree of δ~(13)C positive excursion in shallow-water carbonate is much higher. There are two main causes which should interpret above δ~(13)C positive excursion feature: on the one hand ,much organic carbon take much 12C off when they are buried with a higher speed during the OAE, which lead to the ~(12)C rise of oceanic total dissolved carbon (TDC),on the other hand, during the OAE there are stratification structures in pale-ocean, in the upper mixed layer with high carbon fixation (HCML). There are so much plankton organisms which absorb much ~(12)C as the ~(13)C of shallow-water carbonate in this layer rise higher. Furthermore, on the basis of the theories of carbonate isotope strata, we suggest that the currently used boundary between Aptian and Albian in the studied area is possibly above the international one, which means the main parts of Duoba Member of Duoni Foramatiom in this area should be belong to Albian in stead of Aptian.

Oil and gas exploration of marine strata in China's Pre-Cenozoic residual basins is regarded as a worldwide puzzle because of existent problems and cruxes. Objectively speaking, the subsurface geologic structure is complicated, and the surface conditions of some areas are tough. On the other hand, there are still many problems to be solved in oil and gas exploration technologies of Pre-Cenozoic marine fades, and theoretic cognition about petroleum geology is not profound yet. Therefore, it is principal to explore integrated geophysical research ways of Pre-Cenozoic residual basins. Seismic prospecting and geophysical integrated interpretation technologies aimed at middle Paleozoic marine facies with deeper burial and complicated geologic conditions have not formed due to bad quality of deep strata data. Pre-Cenozoic strata, and especially extension, thickness and internal structure of Paleozoic strata can not be recognized from seismic profiles, so it is hard to systematically cognize structural features and oil-gas resources prospect of Pre-Cenozoic basins. To further investigation of fabric and structural features, basin prototype, formation and evolution pattern of Pre-Cenozoic basins, and also their control over formation, migration and aggregation of oil and gas, will play a guiding and promotive role in developing new surveying areas, selecting advantageous zones and predicting oil-gas resources.This paper follows the modem macrocontrol theory of "Region constrains local, deep strata controls shallow ones", and uses the integrated geophysical method of "One guide, two hinges, three combinations and multi feedbacks'*. Based on several years of geological and geophysical results of the Shengli Oilfield, and 14 newly-joint regional seismic profiles, deep structure and oil-gas bearing capacity of the Jiyang area are discussed and new cognitions are drawn as below.Seismic identification marks Tr, Tg, Tgl and Tg2 are established for importantPre-Cenozoic geological interfaces, and promoted to the whole Jiyang area.Through area-wide tracking and clogging of important seismic reflection marker,the isochronic framework of pre-Tertiary basin is set up in the Jiyang area for the firsttime, which is vital for basin research.Integrated with geological and geophysical research results, the Jiyang area isdivided into four first-order tectonic sequences- basement, lower tectonic layer,upper tectonic layer, and top tectonic layer. The basement and lower tectonic sequence which are related to Pre-Cenozoic are studied with emphasis.Through the research of regional seismic profiles, the point of view is given thatthe Kongdian Formation of Jiyang is structural transition period. The top-bottomunconformable interface of the Kongdian Formation is found out for the first time,and the basin model is determined primarily, which lay a basis for prototype basinresearch of the Jiyang Kongdian Formation.The distribution status of Middle-Paleozoic is delineated in the Jiyang area.The maximum thickness of Paleozoic lies in the top of the south declivity of half-graben. The thickness gets thinner towards the center of Mesozoic and Cenozoic half-graben basin, and even disappears. Structural action in the west-north affects the distribution of Paleozoic residual strata.6. The features of second-order tectonic sequence of the Jiyang depression isstudied and its evolution history of is rebuilt.Combined with the 5-stage evolution history of the China continent and structure evolution features of the Jiyang area, the structure sedimentary process since Paleozoic is divided into 5 periods - basement forming , Indosinian orogenic, Yanshan negative reversal, Himalayan extension and Neogene subsidence period.Combined with the research results of gravity, magnetic surveying and regionalprofiles, this paper brings forward the idea for the first time that the western boundaryof the Jiyang depression is the Ningjin-Yangpan fracture zone, and forms aside-column assemblage with the Wudi fracture zone.The opinion that under Middle-Cenozoic basins in the middle Jiyang area theremight superimpose an old residual basin is given for the first time. And if it is provedto be true, a new exploration space will be pioneered for Jiyang and even north China.There exists many types of tectonic-stratigraphic traps formed under piezotropy,extension and compound action in Pre-Cenozoic Jiyang. Therein all kinds of burialhills are the most important oil-gas trap type of Pre-Cenozoic, which should besurveyed layeredly according to the layout of oil sources.As such a new challenging project and field, the paper systematically analyses different geophysical responses of the Jiyang area, frames the deep structure of the area, and preliminarily recognizes the Pre-Cenozoic residual basins. It breaks through to a certain extent in both theory and practice, and is expected to provide new geophysical and geotectonic clues for deep exploration in Shengli.

心理咨询师的心理需要及相关因素的研究

The aim of this research is to explore the tendency of needs and its influential factors in counselors at present time．Three studies were carried out: study 1 was to find out the tendency of needs and the structure of needs in counselors. Study 2 was to compare the needs between counselors and non-counselors, in which 64 subjects were students majored in psychology but they don’t want to counsel.Study 3 was to initially explore the relationships between the tendency of needs and its influential factors. Studies of the 1 and 3 selected 123 counselors. It was found that: 1. The results of EPPS in counselors: according to comparison between original marks, the number of subjects who range first from high to low was: introspection，change，dominance，nurse，order，succor，affinity=autonomy，achievement，endurance，heterosexuality，deference，aggression=exhibition=abasement ; according to means of original marks, the tendency of needs from high to low was: introspection，achievement，nurse，autonomy，change，succor，endurance，dominance，order，affinity，aggression，exhibition，deference，abasement，heterosexuality. The lower one of the counselors were needs of aggression, exhibition，deference，abasement and heterosexuality，the high one are introspection，nurse and change．The most difference was achievement need. 2. Dilemmas had no significantly different effect on the needs of counselors, but sexuality and age affect them in some factors. There were significant differences in the factors of deference, exhibition and nurse among different ages. Counselors married had higher tendency of obedience, autonomy, introspection, nurse and endurance than those unmarried. 3. The results of EPPS in non-counselors: according to comparison between original marks, the number of subjects who range first from high to low was: endurance，order，change=dominance，autonomy= introspection=nurse，affinity，succor，aggression，achievement，heterosexuality，exhibition=abasement，deference; according to original marks’means, the tendency of needs from high to low was: nurse，endurance，achievement，order，introspection，change，autonomy，dominance，affinity，succor，aggression，exhibition，abasement，deference，heterosexuality. The lower one of the counselors were needs of aggression, exhibition，deference，abasement and heterosexuality，the high one were introspection，nurse and change．The most difference was achievement need. 4. There were significant differences in the needs of abasement and introspection between counselors and non-counselors. Male counselors and non-counselors had significant differences in the factor of abasement. Female counselors had higher tendency of succor needs. 5. The differences of childhood traumas and positive life events were not significant. The positive and negative life events themselves had no significant differences, but negative life events had marginal significant difference between the two groups. 6. The marks of counselors were lower than non-counselors in the factors of neuroticism. 7. Counselors and trainees had no significant differences among other needs、childhood traumas、life events、personality and coping styles except in the deference need. 8. The result of multiple estimation of EPQ , CTQ and EPPS were related．Many specific life events were related with the tendency of many needs. As shown in the research, children’s traumas, characteristic and life events may affect needs chiefly. 9. There were close relation between characteristic and childhood traumas in counselors. Especially the subjects with more childhood traumas had higher tendency of psychoticism, neuroticism and introvision. There were few persons with much high scores on the Childhood traumas in the subjects．Their personality characteristics indicate high extrovision and low psychoticism．Their childhood traumas may affect the shape of sound personality． Conclusion: 1. The most important tendency of needs were introspection，nurse and change． 2. The differences of childhood traumas and life events were not significant between counselors and non-counselors. The marks of counselors were higher than non-counselors in the factors of introspection, but lower in the factor of neuroticism． 3. The main influential factors in counselors of needs were childhood traumas、characteristic and life events.
