应力事件与浊流沉积的时空关系

地球系统科学针对不同的地质、构造、生物和气候现象开展综合研究,分析其内在机理的联系.结合当前国际地学前缘的发展态势,认为应力场和浊流沉积的综合研究将在揭示灾难性地质现象的控制机理、阐明油气资源的成因与分布的同时,为探讨地壳构造变化提供区域性指标.这些指标不仅指示地壳活动的阶段性,还将有助于恢复地幔-地壳-地貌-水流的系统演化历史.特别是深海浊流沉积的综合研究,可望成为“走向深海大洋”、开展深海地学综合研究的另一突破口.

Temperospatial Relationship between Stress Events and Turbidite Deposition

The earth system science targets integrated research on different geological, structural, biological and climatic phenomena and analyzes their interrelationships. Judging from the current trend on international geoscience frontiers, we think an integrated approach for studying stress field and turbidity deposition will help discover the controlling mechanism of catastrophic geological events and illuminate the origin and distribution of oil and gas resources, and it may also provide some regional indices for investigating crustal and structural changes. These indices may not only reveal the stages in regional crustal activity, but also assist in reconstructing the evolutionary history of the mantle, crust, landscape and current systems. An integrated approach toward deep-sea turbidite research may likely become another breakthrough point in our earth system science maneuvers.
