摘    要:从沙捞越盆地形成构造演化入手,分析了造成盆地东部北卢卡尼亚、中卢卡尼亚和巴林基安3个次盆构造差异性的原因,讨论了这种构造的差异性对盆地内沉积的控制作用。认为:婆罗洲逆时针旋转影响下卢卡尼亚陆块向婆罗洲的俯冲碰撞是导致盆地东部各次盆构造差异性的主要原因;受古地貌的影响,中中新世-晚中新世,中卢卡尼亚次盆以发育碳酸盐岩沉积为特征,而北卢卡尼亚和巴林基安2个次盆则主要为海相碎屑岩沉积;中中新世,中卢卡尼亚次盆稳定构造背景为盆地内碳酸盐岩建隆的生长创造了有利条件;中卢卡尼亚次盆内发育的早期断层控制了碳酸盐岩建隆的类型及其分布。

关 键 词:碳酸盐岩建隆    控制作用    构造差异性    沙捞越盆地    婆罗洲

Abstract:Based on the tectonic evolution of the Sarawak Basin, the tectonic differentiation among North Luconia, Central Luconia and Balingian provinces and its control on sedimentation are discussed in this paper. It shows that:1) the subduction and collision of Luconia to Borneo plate, dominated by Borneo's anti-clockwise movement, was the main factor that leads to the tectonic differentiation among North Luconia, Central Luconia and Balingian provinces; 2)sedimentation was controlled by the tectonic differentiation:a) From Middle Miocene to Upper Miocene, Paleotopography dominated the type of sediments. The Central Luconia province was dominated by carbonate sedimentation, while Marine clastics were deposited in the North Luconia and Blingian provinces; b) Despite the intensity of deformation in surrounding areas, the basin remained stable throughout the time of Tertiary to facilitate the carbonate deposition; c) From Oligocene to early Miocene, due to the extensional and strike-slip tectonics, this area formed the southwest to northeast trending graben and horst which dominated the type of carbonate buildups and their distribution
Keywords:carbonate buildups  controlling effect  tectonic differentiation  Sarawak Basin  Borneo
