【摘要】 河流沉积地层是古代陆相沉积和大陆边缘沉积的重要组成部分。河流沉积与气候和海平面升降之间的关系虽然研究较多 ,但是众多的研究集中于河流沉积与相对海平面之间的变化 ,而研究河流沉积与气候的关系则集中于对近 10 0 Ma年以来的河流沉积 ,而对古代河流沉积与气候之间的变化关系研究较少。本文拟对河流沉积与海平面变化和气候变化的响应进行一些讨论更多还原

【Abstract】 Fluvial deposits and strata represent an important component in most ancient continental interior and continental margin successions. Studies of fluvial deposits concerning both climate and sea level changes as well as sequence stratigraphy may become increasingly impotant in this millennium. A variety of explanatory models for fluvial sequence stratigraphy have been published that focus on linking fluvial and nearshore marine strata which have been recognized depositional sequence based on interbeded fluvial and marine strata. Fully nonmarine models have been proposed as well. Studies that link fluvial deposition to climate change in ancient record are relatively sparse when compared with the volume of literature on fluvial responses to sea level change. Modelling fluvial responses to climate change in the ancient record has not been common practice although a number of important efferts have been done. Fluvial systems are sensitive to climatically controlled changes in discharge and sediment load and response to climate change will vary spacially.更多还原
