位于大洋洲新几内亚岛的查亚峰的形成与中新世以来澳大利亚大陆北部被动边缘俯冲碰撞到Melanesian岛弧之下有关.2.8 Ma以来, 查亚峰岩石隆升幅度为7 000 m, 隆升速率为2.5 mm/a, 其剥蚀速率为0.7 mm/a.据查亚峰南坡石炭—二叠系测年得出, 自2.3 Ma以来, 岩石隆升幅度为6 500 m, 隆升速度为2.88 mm/a, 剥蚀速率为1.7 mm/a; 更南可能为前寒武纪的绿片岩分布区, 剥蚀速率更快, 已剥蚀深度达9 km, 是全岛剥露最深的地区.正是这种强烈的切割和剥蚀, 在均衡抬升作用强烈影响下使查亚峰成为大洋洲最高峰. 相似文献

Throughout the contemporary Pacific, relationships that indigeneity makes possible are emerging as celebrated resistance to post-colonial development anxieties. In the process, lived experience heightens the commitment to decolonize thinking, language and practice in teaching and research. Not only because these imperatives are highly personalized but also because they are gendered and heavy with generational trauma. These gendered dynamics circulate around popular culture and imaginaries of Pacific paradise but also problematically around the challenges of long-standing intolerances especially around gender and race. The paper asks how a gendered politics of positionality engages with emerging positionalities that uncritically allow for such intolerances. I touch on two ways in which colonial continuities of belittlement are often reinforced, but are also offering hopeful and careful decolonial scholarly futures. The first is the naming of the Pacific and the second is supervising women doctoral candidates from the Pacific. In this paper, the audacity of the ocean offers a metaphorical opportunity to carefully reconcile these tensions and provide trajectories for decolonial knowledge-making. However, it also offers a material way of understanding the on-going work with ‘tensions’ and disruptions in their ever present but changeable forms. Oceanic tropes and a feminist Oceanic audacity of embodied engagement in the Pacific offer dynamic and gendered intellectual agility which runs counter to the tropical imageries of languid indifference.

Is it possible that education in the Global South leads to emigration and is therefore detrimental to development prospects? For the Pacific Islands region, this issue is particularly pertinent, given the high rates of migration and the strong emphasis placed on education as a basis for development. Although our knowledge of the bilateral relations between, respectively, education and development, education and migration, and migration and development have advanced, we know very little of the complex interplay between the three. In this article, we suggest a new approach to the trilateral relationship among education, migration and development in the Pacific Islands which may have implications beyond that region. 相似文献

从太平洋4台的分析显示，APIA，GUAM和PAMATAI台Z分量的太阳黑子周变化与HONOLULU台的相位相反。可是，CANBERRA台的变化又和HONOLULU台同相。这种表现复杂的地方性差异，更反映出太阳黑子周变化源于外场之说的有问题的。 相似文献
