Baltica was one of continents formed as a result of Rodinia break-up 850-550 Ma. It was separated from Amazonia(?) by the Tornquist Ocean, the opening of which was preceded by Neoproterozoic extension in a network of continental rifts. Some of these rifts were subsequently aborted whereas the Tornquist Rift gave rise to splitting of Rodinia and formation of the Tornquist Ocean. The results of 1-D subsidence analysis at the fossil passive margin of Baltica provided insight in the timing and kinematics of continental rifting that led to break-up of Rodinia. Rifting was associated with Neoproterozoic syn-rift subsidence accompanied by deposition of continental coarse-grained sediments and emplacement of continental *** from a syn-rift to post-rift phase in the latest Ediacaran to earliest early Cambrian was concomitant with deposition of continental conglomerates and arkoses, laterally passing into mudstones. An extensional scenario of the break-up of Rodinia along the Tornquist Rift is based on the character of tectonic subsidence curves, evolution of syn-rift and post-rift depocenters in time, as well as geochemistry and geochronology of the syn-rift volcanics. It is additionally reinforced by the high-quality deep seismic reflection data from SE Poland, located above the SW edge of the East European Craton. The seismic data allowed for identification of a deeply buried(11-18 km), well-preserved extensional half-graben, developed in the Palaeoproterozoic crystalline basement and filled with a Neoproterozoic syn-rift volcano-sedimentary succession. The results of depth-to-basement study based on integration of seismic and gravity data show the distribution of local NE-SW elongated Neoproterozoic depocenters within the SW slope of the East European Craton. Furthermore,they document the rapid south-eastwards thickness increase of the Neoproterozoic succession towards the NW-SE oriented craton margin. This provides evidence for extensive crustal thinning o

"赛里斯(Seres)"源自古罗马文献,与早期希腊语源有所关涉,用来指称"中国",或者"中国人",这种观点为学者乃至普通人广泛接受。但本领域专家学者,包括许多名动一时的汉学家,却从未停止对这一语词来源与传播等方面的探究,火花四溅的论争也因此彼伏此起。辩难和论战结果直接或间接地导致了长久以来定式观念的逐渐松动,包括被证伪或进一步坐实,可资信据的合理解释进入人们的视野。揭开重重迷障,推证赛里斯(Seres)与印度密切关联,而罗马人的赛里斯(Seres)-丝国非中国莫属。

水力压裂技术已经广泛应用于煤层气抽采以提高抽采效率。水力压裂产生裂缝的空间分布评价对于提高资源的利用率和降低潜在的瓦斯突出风险至关重要。在水力压裂过程中,裂缝的产生会伴随微地震的产生,因此微地震监测可以用于水力压裂效果的评价。目前煤层气水力压裂微地震监测主要是依赖微地震定位得到的空间分布,不能准确和全面评价储层的改造效果。为此,提出综合利用微地震定位和速度成像综合评价煤层气水力压裂改造效果。针对中国山西的两口煤层气水力压裂井地面微地震监测数据,利用双差地震成像算法确定了更精确的地震定位和目标煤层附近的速度异常分布。定位结果显示微地震主要分布在压裂井附近并且呈簇状分布,和传统定位相比双差成像给出了更精确的微地震空间分布。根据微地震的空间分布,估算了储层的压裂改造区域。双差地震速度成像显示微地震位于相对低的v P异常、高的v S异常和低的v P/v S异常区域。结合前人岩石物理实验结果,推测在微地震刻画的储层改造区,裂缝中的煤层气处于饱和状态,表明水力压裂有效释放了煤层气。因此综合通过微地震定位和速度成像可以更全面地刻画煤层的改造情况。
