1Late Cenozoic seismic stratigraphy of the Andaman Forearc Basin,Indian Ocean显示文摘Interpretation of new multichannel seismic reflection data from the Andaman Forearc Basin(AFB) in the northern Indian Ocean is presented here. The highquality multichannel seismic data from the Andaman Forearc region enable us to examine the seismic characters and to demarcate seismic sequences bounded by distinct unconformities. Ages of marked seismic horizons have been calibrated with available litholog data from nearby industry boreholes. Seismic interpretation of new data shows that the AFB is filled with * 4.5-s-two way travel time(TWT) thick Neogene to Recent sediments. The entire basin assemblage exhibits two distinct major sequences pertaining to the Neogene and Quaternary times. A large part of the basin is filled with intermittent mass transport deposits(MTD). We infer that the episodic uplift of the Invisible Bank, protuberance of the outerarc and regular deformation through reactivation of preexisting normal faults since the Pleistocene could be attributed as causal mechanisms for the MTDs. Strong bottom simulating reflectors are identified in the Late Miocene and younger sediments of the outerarc and AFB at a depth of * 0.6 s TWT and correspond to the presence of gas hydrates in this region. Our interpretations have significant implications for geodynamic as well as resource exploration in the AFB.Dhananjai K.Pandey Goli Anitha Ramesh Prerna Anju Pandey 2017Petroleum Science2017,14,4:3
2Structural Characteristics of the Andaman Forearc Inferred from Interpretation of Multichannel Seismic Reflection Data显示文摘安达曼群岛 Forearc 盆(AFB ) 在配置是不对称的并且用 ∼6 填满晚第三纪的 km 厚的堆积到最近的沉积(在双向旅行时间的 ∼4 s:TWT ) 与不同带状配列。它显示出与 1:30 的一个海床坡度的近东方结束的直到 ∼3 km (在 TWT 的 0.8 s ) 的渐渐的变瘦。Outerarc 的厚使变形的沉积 ∼2 s (TWT ) 与强烈指责被联系,偶尔的合拢由最近的 tectonics 引起了。在 upwarped 以内的一系列差错的开发渐新世顶到的沉积的列最近与旋转差错块被观察。这些特征是最近的火的侵入的表明,并且揭示温和 N-S 有压缩性的政体的存在。它 AFB 上的效果导致了进一步沉积高举,它现在能被看作不可见的银行。支持我们的地震解释的前面的严肃建模表明它从莫霍(∼9 km 深度) 与火的侵入被联系,并且也建议那个大陆人外壳位于 AFB 下面。象在在在海床下面的 0.6 s 的深度的 Outerarc 和 Forearc 盆的中新世的沉积的特征一样的强壮的底部模仿反射镜(BSR ) 在 AFB 建议煤气的水合物的推断的可能的出现。Anitha GOLI Dhananjai K.PANDEY 2014Acta Geologica Sinica(English Edition)2014,88,4:2
