Varigrained, often coarse-grained textures of deposits, their sedimentary structures indicating the development of erosional surfaces and channels, lingoid subaqueous dunes and bars, the dominant current direction and channel orientation to the south, southeast and southwest, as well as the absence of tidal features (e.
These sediments are deposited in one depositional sequence with erosional sequence boundaries (SB1); The beginning of sequence belongs to clastic deposits, grading upward to salina evaporites and interbeds with shale and marl with no fossils (LST) and so transgressive marl belonging to open marine (TST) overlying by shallower limestone deposits (HST).
Classically, hypsometric analysis has been used to differentiate erosional landforms at different stages of their evolution (Strahler, 1952; Schumm, 1956).
137]Cs inventories from erosional to depositional areas; that is, SOC and TN increased with increasing [sup.
The beach elevations measured before (on the 17th and 18th of August 2001) and after (on the 20th) an erosional event show good agreement between the two different measuring methods.
In this group, both preservation biases from weathering and erosional processes have been recognized.
Erosional development of streams and their drainage basins: hydro physical approach to quantitative morphology: Geological Society of America Bulletin.
Among the topics are classic Precambrian geology of northeast Minnesota, layered intrusions of the Duluth Complex, a glacial record spanning the Pleistocene in southern Minnesota, and Holocene landscape evolution and erosional processes in the Le Sueur River in central Minnesota.
This new study supports an alternative hypothesis that persistent warm water was confined to the subsurface and many erosional features were carved during brief periods when liquid water was stable at the surface.
The name Leonard comes from Malott's reference to an erosional steephead with limestone springs (Malott,1952).
The size and rates of erosional downcutting of individual straths differ from one structural unit to another irrespective of climatic or lithologic controls, implying neotectonic influences (Starkel, 1994; Schumm, 1986; Blum and Tornqvist, 2000; Brocard and van der Beek, 2006).
Interpretation of the seismic data indicates that an erosional event occurred during the Upper Cretaceous age and caused the chalk to thin from 1,000 feet to 450 feet in some sections.
