Sedimentary basin - Wikipedia
网页Sedimentary basins are region-scale depressions of the Earth's crust where subsidence has occurred and a thick sequence of sediments have accumulated to form a large three-dimensional body of sedimentary rock. [1] [2] [3] They form when long-term subsidence creates a regional depression that provides accommodation space for accumulation of sediments. [4]Over millions or tens or hundreds of ...
网页Sedimentary basins range in size from as small as hundreds of meters to large parts of ocean basins. The essential element of the concept is tectonic creation of relief, to provide both a source of sediment and a relatively low place for the deposition of that sediment.
Sedimentary Basin - an overview | ScienceDirect Topics
网页A sedimentary basin is an area of the Earth’s crust that is underlain by a thick sequence of sedimentary rocks. Hydrocarbons commonly occur in sedimentary basins. Most basins cover tens of thousands of square kilometers and may contain more than 5 km of sedimentary fill.
Sedimentary Basins - SpringerLink
网页2019年12月11日 · Sedimentary basins are regions of prolonged subsidence of the Earth’s surface that provide the accommodation space for mineral and organic material (Allen and Allen 2013). These deposits – the sedimentary rocks – are the record of the past geological history including tectonic events, climatic conditions, changes in …
6.3: Depositional Environments and Sedimentary Basins
网页2024年4月24日 · Trench basins form where a subducting oceanic plate dips beneath the overriding continental or oceanic crust. They can be several kilometers deep, and in many cases, host thick sequences of sediments from eroding coastal mountains.
Geodynamic mechanism and classification of basins in the Earth system
网页2022年2月1日 · The sedimentary basin refers to a certain tectonic subsidence area on the Earth’s surface filled by sedimentary material and water loading. As one of the main units of global tectonics, the lifecycle of the sedimentary basin is controlled by global plate tectonics and its evolution.
Sedimentary Basin - an overview | ScienceDirect Topics
网页A sedimentary basin is an area of the earth's crust that is underlain by a thick sequence of sedimentary rocks. Hydrocarbons commonly occur in sedimentary basins and are absent from intervening areas of igneous and metamorphic rocks (North, 1971).
INTRODUCTION | The Dynamics of Sedimentary Basins | The …
网页Sedimentary basins are places where subsidence of Earth's crust has allowed sediment to accumulate on top of a basement of igneous and metamorphic rocks. Over geologic time these sediments and associated fluids are chemically and mechanically transformed through the compaction and heating associated with basin subsidence.

网页Giant and supergiant petroleum fields and significant petroleum-producing basins of sedimentary rock are closely associated. In some basins, huge amounts of petroleum apparently have been generated because perhaps only about 10 percent of the generated petroleum is trapped and preserved.

网页2024年8月22日 · Sedimentary Basins Are Needed to Collect Sediment; Sedimentary Records of Sea-Level Change. Eustatic or Relative? The setting in which sediments are accumulated is called a depositional environment. (Some of the more important of these environments are illustrated in Figure 9.19.)
