Exam 10: Crustal Deformation and Mountain Building

Grabens are formed by what type of faulting?

The Tibetan plateau is high above sea level because ________.

A(n)________ fault forms when the hanging wall moves down relative to the footwall .

Was this mountain building process an Andean type mountain building event,a collisional event,or both; and what might have been subducted to produce the over-thickened oceanic crust that drove the orogeny?

In the figure below,which occurred first,the folding or the faulting? Briefly explain your answer.

Based on your knowledge of isostasy,would you expect thicker or thinner crust beneath the Caribbean Islands (e.g.,nearD)than the continental region of Venezuela to the south?

In the figure,which of the deformations appears most similar to what might be expected along a transform plate boundary?

Exhumed basins contain ________ rocks in the center of the structure and domes contain ________ rocks in the center.

A(n)________ is a thick accumulation of sediments and small tectonic blocks formed of material scraped off subducting oceanic lithosphere at a convergent margin.

Refer to the figure below,captured from Google Earth,for the following questions. -This mountain belt would be called ________.

In an overturned fold,the beds have rotated ________.

Island arc systems now on the Tibet plateau record subduction prior to the collision of India with Eurasia.Geologists would map these pre-collisional arc rocks as ________.

Most granitic batholiths represent ________.

________

Which letter in the figure corresponds to a "fault"?

In thrust faulting,________.

Refer to the figure below,captured from Google Earth,for the following questions. -At location B you might expect to find a ________ basin

What is the modern theory for orogenesis?

Terrane accretion generally occurs along a divergent boundary between a continental plate and an oceanic plate.

When the differential stress exceeds the strength of the material,the material will begin to undergo elastic strain.
