A possible model for the formation of these features follows. The early Flood unleashed the mechanism of the Flood, which I think was caused by impacts. 9 The very early Flood should be the most catastrophic part of ... Data points are shown for cratonic peridotites, data fields for oceanic mantle (abyssal and ocean island peridotites) and modified cratonic mantle, for example, the eastern North China craton.

5 a - The unconformities that form the boundaries of cratonic sequences are considered the result of eustatic lowering of sea level because they are sequence - bounding conformities that are caused through change in sea level . If the unconformities were caused by an uplift it would 've had to occurred by all cratons uplifting and not just ...rude and Lithgow-Bertelloni, 2005]. Three, the cratonic profiles contain very high shear wave speed (4.7- 4.8 km/s) in the shallow mantle; any model describing the thermal and chemical structure of cratons must be consistent with these values. Four, the details of the magnitude and shape of cratonic shear-velocity pro-

A cratonic sequence refers to a very large-scale lithostratographic sequence that covers a complete marine transgressive-regressive cycle across a craton.They are also known as "megasequences", "stratigraphic sequences", "sloss sequence" or simply "sequences."

This simplified diagram explains how cratons might have formed. (a) Hot rock upwells from the deep Earth. (b) This material collides with existing lithosphere (surface rock) and melts it.cratonic sequence A large package of sedimentary rock, in some places 100s to 1000s of feet thick, which are bounded by regional unconformities; these sequences represent sedimentary deposits formed between great transgressions and regressions of the sea across the continents, including the North American continent.

Well-known difficulties in applying sequence stratigraphic concepts to deposits that accumulated across slowly subsiding cratonic interior regions have limited our ability to interpret the history of continental-scale tectonism, oceanographic dynamics of epeiric seas, and eustasy. We used a multi-disciplinary approach to construct a high-resolution stratigraphic framework for lower Paleozoic ...

Jan 1, 2008 · Definition of the cratonic sequences of North America by Sloss (1963) provided the foundation for much of the sequence stratigraphic model developed since (e.g. Vail et al., 1977).

A craton ( / ˈkreɪtɒn /, / ˈkrætɒn /, or / ˈkreɪtən /; [1] [2] [3] from Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere, which consists of Earth's two topmost layers, the crust and the uppermost mantle. The Sloss cratonic sequences record the history of this dynamic tectonic environment, in the form of episodes of transgression, varied deposition, regression, and erosion and nondeposition, occurring on a time scale of tens of millions of years. These sequences occur across the craton, on areas of platform, as well as in the four main ...The possible affinity of the Sauk sequence with this pattern of cratonic differentiation is less clear.

North America, for example, has four cratonic sequences dated to the Paleozoic. In each sequence, rocks indicate that the North American craton was covered by transgression of a shallow sea, which then regressed.
