What is the meaning of Tectonostratigraphic?
What is the meaning of Tectonostratigraphic?
From Wikipedia, the free encyclopedia. In geology, tectonostratigraphy is stratigraphy that refers either to rock sequences in which large-scale layering is caused by the stacking of thrust sheets, or nappes, in areas of thrust tectonics or to the effects of tectonics on lithostratigraphy.
What is a Synrift?
The syn-rift/post-rift transition represents a gradual change from extensive fault activity through localized faulting and passive infill to sporadic faulting during post-rift times. Areas in which the Transition Sequence is developed usually have an element of fault control, especially during the early stages.
What is syn in geology?
The term syn-sedimentary tends to be used rather loosely, as deformation that takes place during or soon after deposition; the ‘soon’ is the loose part of this broad definition. Sediment begins to compact almost immediately following deposition, where framework grains begin to move closer together.
What is syn rift and post-rift?
The syn-rift/post-rift transition represents a gradual change from. extensive fault activity through localized faulting and passive infiil to sporadic faulting. during post-rift times. This Transition Sequence is present in localized areas (sub-basins).
What stratigraphy involves?
Stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale. It provides a basis for historical geology, and its principles and methods have found application in such fields as petroleum geology and archaeology.
How are terranes formed?
In geology, a terrane (in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or “sutured” to crust lying on another plate. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation.
What causes rifting?
Rifting can be caused when hot material from a mantle plume reaches the base of a continental plate and causes the overlying lithosphere to heat up. In addition to this the uwards movement of the plume against the base of the plate results in extensional forces, which can cause rifting.
What is an ocean rift?
In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.
How does geology affect my life?
Geology in everyday life is not restricted to resources. It is also about hazards and risk associated with rock falls, radon, landslides, quick clay, landslides and earthquakes. Geology helps us understand climate change in the past, which may help us predict future scenarios.

How is a rift valley formed?
A rift valley is a lowland region formed by the interaction of Earth’s tectonic plates. A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.
What is collapse of rift?
A higher frequency of intrusive events along rift zones leads to elongated topographies of the affected edifices. The extensional character of these events can contribute to flank instability and mass wasting events where whole sections of the volcanic edifice can collapse along rift zone boundaries.
