中国南方中、古生界古今油气藏形成演化控制因素及勘探方向

根据南方多期构造改造及油气演化复杂性的特点 ,将南方中、古生界古今油气藏分成原生、次生及再生烃油气藏 3类。原生及次生油气藏的分布主要受生烃凹陷邻近的古隆起及古斜坡控制 ,再生烃油气藏分布主要受“二次生烃”或晚期生烃中心控制。南方现存的中、古生界工业性油气藏特别是天然气藏的成藏期均较晚 ,以第三纪为主 ;南方中、古生界烃源岩存在早期—晚期的多期生烃、多期成藏 ,而勘探的重点应该是晚期生烃及晚期成藏的油气藏。晚侏罗世—早白垩世燕山运动对南方中、古生界原生油气藏的保存与破坏起到了决定性的作用 ,它控制了现今南方中、古生界主要油气藏成因类型———次生型及再生烃型油气藏的分布。上扬子地区主要考虑次生气藏的勘探 ,中、下扬子地区主要考虑再生烃油气藏的勘探。

PALAEOZOIC TECTONIC PALAEOGEOGRAPHY OF THE CATHAYSIA IN EASTERN ZHE JIANG AND NORTHERNFUJIAN, CHINA

Based on the data about sedimentary facies and palaeogeography, this paper proves the existence of the Cathaysia (the part in eastern Zhejiang and northern Fujian, the same hereinafter) and makes a survey about its palaeogeography since Sinian Period. It also discusses the evolution of the tectonic environment of this region during Phanerozoic Eon, according to the features such as the composition of sandstones derived from the old land and alkalinity of volcanic rocks and so on. Continuous uplifting was maintained in Cathaysia during Sinian Period and Paleozoic Era, typically with no significant tectono-magmatic activity being observed. Its northwestern margin belongs to the type of passive continental margin during the middle and late phase of Caledonian Cycle. It showed the characteristics of a steady continent in late Paleozoic era, but was turned quickly into an active continental margin after the middle Jurassic period.

Fossil biotas from Pakistan with focus on dinosaur distributions and discussion on paleobiogeographic evolution of Indo-Pak Peninsula

Recent geological and paleontological exploration in the Indus basin of Pakistan allowed the discoveries of numerous remains of non-marine reptiles( titanosaurian sauropod,abelisaurian and noasaurian theropod dinosaurs),and marine reptiles( crocodiles),flying reptiles( pterosaurs),marine and non-marine mammals,fishes,invertebrates,and plants,especially Pakistan is relatively rich in footprints / trackways in the Mesozoic.These vertebrates of Indo-Pakistan are very significant for paleobiogeographic study due to the present-day connection of this continent with Asia in Northern Hemisphere,whereas during past( Jurassic and pre-Jurassic) it was connected to the Gondwana. The Mesozoic vertebrates show close affinities with Gondwanan landmasses.The Cenozoic vertebrates show Eurasian affinity and migrated from Indo-Pak subcontinent to Eurasia or vice versa via Paleo Indus River systems along Western Indus Suture,after long journey of about 6 000 km the first collision of Indo-Pak subcontinent with Asia occurred at terminal Cretaceous.

Yogic Prescription for Corporate Wellness and Excellence

Yoga has been practiced as a complete way of life management and ecological harmony for time immemorial. Successful companies across the globe like Microsoft, IBM, and PepsiCo etc., have incorporated yoga or spirituality at their workplaces for employees＇ wellness and organizational excellence. In contemporary scenario, scientific researches on yoga that substantiate its positive impacts at bodily, psychic, societal, spiritual and organizational level have been made abundantly. However, there is a lack of an innovative yogic model that is holistic and supportive to boost corporate wellness （CW） and excellence （CE）. So the basic aim of this paper is to propose a yogic prescription CYP） for the corporate wellness and excellence that needs to be tested in future researches.

Biogeographic characteristics of Zhesi brachiopod fauna and reconstruction of tectonopaleogeography of Jiamusi-Mongolia Block

The Kungurian-Capitanian （Permian） Zhesi branchiopod fauna is mainly composed of cold-water typed taxa with high diversity and abundance. This fauna is similar with the coeval brachiopod faunas from Ti- man-Pechora, Svalbard, and Queen Elizabeth Islands of the Boreal Realm, with no real ＂warm-water＂ species. Zhesi brachiopod fauna is a cold-water fauna and should be assigned to the Boreal Realm. Considering the paleogeographic characteristics of this fauna and the basic rationale of paleobiogeographie provinces being controlled by latitude-temperate, and that the above areas were located at 50°N -70°N in the global paleoclimate reconstruction map compiled by Boucot et al. , the paleo-latitude of the southern margin of Jiamusi-Mongolia Block, where developed the Zhesi brachiopod fauna, is suggested ranging from 40°N to 60°N. Zhesi brachiopod fauna is an endemic fauna, containing more than 75% endemic species and self-grouped as a biogeographic province, termed Inner Mongolia Province. These characteristics indicate that this area was closed or semiclosed at that time. On the Jiamusi-Mongolia Block, the Herlen-Jiamusi Old-land as an obvious ＂continental barrier＂ hindered the northward migration of the Zhesi brachiopod fauna and the immigration of brachiopod species from other areas. The Tarim plate has collided with the Kazakhstan plate and the western part of South Tianshan-Beishan-Xar Moron Ocean has been closed. At the same time, the western margin of Jiamusi-Mongolia Block was joined with the Tarim plate. The Xar Moron Ocean in south of Jiamusi-Mongolia Block was wide e- nough and the ocean temperature rose gradually southward, so that it is not suitable for the cold-water brachiopods to survive and thrive on the northern margin of the North China plate. Thus, the ocean with large width and high temperature formed another natural barrier for the southward migration of the cold-water brachiopods.

An Assessment of Strategies for Cultural Heritage Management and Tourism Development in the Eyasi Basin, Northern Tanzania

This paper assesses the manner in which a local community has been incorporated into the management and utilization of cultural heritage resources in the lake Eyasi basin, northern Tanzania, in order to reduce poverty. One of the most important programs used to encourage rural developments is the outlay of cultural tourism. Lake Eyasi region is one of the few regions in Tanzania with brilliant cultural heritage resources including archaeological sites and distinctive indigenous cultural traits that cannot be seen in other places across Eastern Africa. Archaeological records of this region exhibit the earliest evidence for hominin morphological change from archaic to modem humans. It is also coherent key development traits including complex lithic technologies and artistic imaginations as it is the case for all living people. Ethnographic research in the region sheds light on the living standards of a modem foraging community that has consistently relied on wildlife resources for several decades. Both archaeological and ethnographical aspects have made this region an enduring attraction for tourists to seek a unique experience and gain an appreciation for the past. Even though there are positive impacts of tourism on rural development, there are potential challenges that need immediate attention.

Coevolution of brachiopod paleobiogeography and tectonopaleogeography during the late Paleozoic in Central Asia

Patterns of brachiopod paleobiogeographic regionalization in Central Asia reveal a coevolution between brachiopod paleobiogeography and tectonopaleogeography during the Early Devonian,Early Carboniferous,Late Carboniferous,Early Permian,and Middle Permian.The coevolutionary relationship reasonably accounts for the formation mechanisms of brachiopod paleobiogeography in this region,and also provides a basis for studies on the location and configuration of oceans and plates(blocks)during the late Paleozoic in Central Asia.

Heavy mineral assemblage characteristics and the Cenozoic paleogeographic evolution in southwestern Qaidam Basin

Based on the analysis of heavy mineral assemblages in Cenozoic southwestern Qaidam Basin, we found that different areas have variable heavy mineral assemblage characteristics, which suggested that there were two source areas--the Altyn Moun- tains and the Qimen Tagh-East Kunlun Mountains. In Ganchaigou-Shizigou-Huatugou （Area A）, which was mainly source from the Altyn Mountains, its heavy minerals were mainly composed of zircon, Ti-oxides, and wollastonite in the Paleocene- early Eocene and mainly of unstable minerals, especially amphibole, in the middle Eocene-Oligene. Since the late Oligocene- Miocene, the heavy minerals were still mainly unstable minerals, but the content of epidote increased and the content of am- phibole decreased. In Qigequan-Hongliuquan （Area B）, which was the mixed source from the Altyn Mountains and the Qimen Tagh-East Kunlun Mountains, its heavy minerals were mainly garnet, epidote, and amphibole. The source of Lticaotan- Dongchaishan-Kunbei （Area C） was mainly from the Qimen Tagh-East Kunlun Mountains, heavy minerals in the sediments in Area C were mainly zircon and Ti-oxides in Paleogene and garnet, epidote, and amphibole in Neogene. In Yuejin-Youshashan （Area D）, where the stable minerals and unstable minerals were present simultaneously, the heavy mineral assemblages was controlled by multi-direction source. The variation of heavy mineral assemblages in southwestern Qaidam Basin shows that Altyn Mountains was of low-lying topographic relief in Paleocene-early Eocene, and the rapid uplift of Altyn Mountains started from the middle Eocene. In Paleogene, the Altyn Tagh Fault had a slow strike-slip velocity, but the strike-slip velocity increased greatly since the late Oligocene, leading to a strike-slip displacement above 300 km since Neogene. Meanwhile, the Qimen Tagh-East Kunlun fault zone was under a stable tectonic stage in Paleogene with the Qimen Tagh Mountain being low- lying hills; since the late Oligocene, the fault zone started to activate and the Qimen Tagh Mountain began to uplift rapidly.
