Further north on the Lofoten margin, reverse modelling of post-breakup subsidence with a 尾 stretching factor of infinity predicts palaeo-bathymetries of 1500m to the west of the Utrst Ridge and fails to restore Lower Eocene sediments and flood basalt tops to sea level at 54Ma. If these ...
韦伯海槽,位于南班达海盆东侧,最大水深约7400 m,是世界上最深的非俯冲盆地之一。其形成时代应为晚上新世至更新世(Charlton et al., 1991),是弧前环境拉伸形成的最新盆地。Hinschbergeret al.(2005)推测韦伯海槽形成于3~1 Ma,是澳大利亚—班达弧的汇聚,班达弧弯曲导致弧后扩张的结果。 现在班达弧由火山内弧和...

The middle slope area along CDP3 line may have subsided as much as 3 km during the past 2 Ma at a rate of 1500 m.Ma-1. Estimates of the volume of material eroded from Peru margin can be derived from the amount of subsidence alon CDP1 and CDP3. Along CDP1 the estimated erosion ...
site: e = end or edge, m = middle, r = rim/overgrowth. CL image microstructure: osc = oscillatory zoning, h = homogeneous (d = dark or b = bright); sz = sector zoned. U-Pb data corrected for non-radiogenic Pb based on measured 204Pb and 900 Ma model Pb of Cumming and Richard...

Subsequent deformation, ca 1550 – 1500 Ma, resulted in upright to steeply inclined folding of the earlier fabrics and steeply east-dipping reverse faults. This orogenic phase was characterised by the growth of staurolite in aluminous schists, and its subsequent replacement by biotite, ...

This study has documented the sequence stratigraphic architecture of the Matemateaonga Formation, which is an approximately 1100 m-thick succession of strongly cyclothemic, unconformity bounded shelfal strata of late Miocene (late Messinian) to early Pliocene (early Zanclean) age (c. 5.5-4.7 Ma)...
