西藏高原西、中、东的分段性及其意义

经过近几十年的研究,人们已经普遍认为青藏高原是由几条近东西向的块体先后拼贴而成,大型的东西向构造是高原内部最明显的构造特征。然而根据最近所获得的有关西藏高原以及附近地区的重力场、地震层析成像、地震活动性、水平位移速度场以及地质等资料,发现整个西藏高原内部存在着明显的两条重要的南北向或近南北向构造和一些小型的南北向构造,它们将西藏高原划分为西、中、东三个有各自构造特点的部分;西侧的南北向构造沿84°～85°E延伸,东侧的近南北向构造位于92°～94°E之间。这两个构造带在上述的多种地球物理资料中均有良好的显示,是重要的重力异常变异带、重要的热结构边界带、重要的地震活动带,也是明显的地貌陡变带,等等。高原西部地形崎岖,剥蚀最深,布格重力异常最高,目前向北北西方向运动;中部地区地表平坦,发育众多的南北向地堑裂谷,东西向伸展活动最明显,海拔最高,集中分布了7座超过8000m的高峰,目前向北东东方向运动;而东部地区地形也比较崎岖,发育许多目前仍在强烈活动的走滑断层,在这些断层之间,地块相对转动,目前向北东甚至南东方向运动。造成西藏高原东西分段的原因现在还不清楚,笔者等倾向认为造成这种现象可能是由于与欧亚板块发生碰撞的印度板块在横向上也是西、中、东分段的,印度

论江苏若干矿产资源开发利用的新方向

江苏泥炭大多数为低有机质分解较强的低位泥炭，适于制作肥料或制成腐肥使用；江苏硅质原料丰富，一种以硅为主的化肥——硅肥正日益显示其重要性；湖泊淤泥具有颗粒微细、含砂量少、可塑性高、结合力强、干燥敏感性好和收缩率较大等特点，是生产空心砖的最佳原料；高家边组泥页岩和坟头组底部细粉砂质泥岩及泥质粉砂岩是良好的陶粒原料、砖瓦、陶瓷建材以及水泥用粘土质原料；利用矿泉水与茶的结合能够生产出高、中、低多效应的复合型新产品。上述尚未被利用或利用程度不够的矿产资源有着广泛的开发利用前景。     

Subsurface Occurrence of Natural Gas Hydrate in the Nankai Trough Area: Implication for Gas Hydrate Concentration

Abstract. The Nankai Trough runs along the Japanese Islands, where extensive BSRs have been recognized in its forearc basins. High resolution seismic surveys and site-survey wells undertaken by the MITI have revealed the gas hydrate distribution at a depth of about 290 mbsf. The MITI Nankai Trough wells were drilled in late 1999 and early 2000. The highlights were successful retrievals of abundant gas hydrate-bearing cores in a variety of sediments from the main hole and the post survey well-2, keeping the cored gas hydrate stable, and the obtaining of continuous well log data in the gas hydrate-dominant intervals from the main hole, the post survey well-1 and the post survey well-3. Gas-hydrate dominant layers were identified at the depth interval from 205 to 268 mbsf. Pore-space hydrate, very small in size, was recognized mostly filling intergranular pores of sandy sediments. Anomalous chloride contents in extracted pore water, core temperature depression, core observations as well as visible gas hydrates confirmed the presence of pore-space hydrates within moderate to thick sand layers. Gas hydrate-bearing sandy strata typically were 10 cm to a meter thick with porosities of about 40 %. Gas hydrate saturations in most hydrate-dominant layers were quite high, up to 90 % pore saturation.
All the gas hydrate-bearing cores were subjected to X-ray CT imagery measurements for observation of undisturbed sedimentary textures and gas-hydrate occurrences before being subjected to other analyses, such as (1) petrophysical properties, (2) biostratigraphy, (3) geochemistry, (4) microbiology and (5) gas hydrate characteristics.

海岸带临港工业、海运物流与全球化大生产的探讨

海岸带是世界人口密集、经济发达的地带，在全球经济一体化和全球化大生产中具有重要的地位。近半个世纪以来，海岸带临港工业迅速崛起并持续高速发展，依托海港建设、大型船舶运输发展起来的临港工业和海运物流，在跨国公司的运作下形成了现代意义上的全球化大生产。这种生产方式使资源贫乏的日本快速发展成发达国家；深圳赤湾临港工业区成为中国高效益工业的典范。本文着重讨论了海岸带经济建设中大力发展临港工业对地区、国家和全球经济的影响，指出中国21世纪应大力开发利用海岸带港湾资源、重点建设全球化大生产的大进大出的基地，建立若干个具有国际竞争力的海岸带产业中心，推动国民经济持续、快速发展。     

Place‐based action in Wollongong: the role of union–community alliances in constructing labour geographies of steel

Place‐based action (PBA) features prominently in labour geographies, particularly in restructuring politics, and is consistently employed as an enduring union tactic, yet it remains relatively undervalued in steel restructuring accounts, with common approaches emphasising the class instability and limitations of such action. In contrast, and to redress the apparent imbalance, this paper argues the merit of recognising PBA as a distinct movement‐based politic with specific forms of representation and empowerment. Such an approach should lead to greater recognition and appreciation of the impact that PBA has had historically. To illustrate this, a case study is presented of how local groups used place‐based action in Wollongong to shape steel restructuring politics and industry policy during the 1980s. Although powerful, the influence of PBA diminished at the policy writing stage. Rather than devaluing all benefits from PBA due to such limitations, it is suggested that the constraints on PBA at this point suggests the need for other forms of intervention. It is concluded that the approach suggested here highlights when other tactics are required, strengthening real‐world tactical analysis.
