Sandstone depositional environment
Mar 3, 2023 · A depositional environment, which is also known as a sedimentary environment, is a physiographic setting, where sediments are deposited. A depositional environment can be presented by a river, a lake, a delta, a lagoon or an ocean. Each depositional environment imparts distinctive signatures to the sediments, which is typical of the processes ... Figure 6.3.1 Some of the important depositional environments for sediments and sedimentary rocks. Table 6.4 provides a summary of the processes and sediment types that pertain to the various depositional environments illustrated in Figure 6.3.1.

This paper presents the facies and depositional environment of the early Miocene Dam Formation, Eastern Arabian platform, Saudi Arabia. Deposition of Dam Formation (Fm.) was considered as a restricted shallow marine deposition. Few studies suggest the role of sea-level change in its deposition but were without decisive substantiation. Here, we describe the facies and high-resolution model of ...Stephen Ehrenberg. none.

The studied samples show Ce/Ce ...
