STRUCTURAL GEOLOGY HATCHER 16

Question 1

Any structure that can constitute a frabric that is expressed as a real or imaginart line

Answer 1

Lineation

Question 2

a topographic feature consisting of straight or aligned surficial features such as valleys and ridges

Answer 2

Lineament

Question 3

Lineations that are confined to isolated surfaces in a rock mass

Answer 3

Non Penetrative

Question 4

Most common mesoscale non penerative lineation which are direct result of frictional sliding and flexural slip

Answer 4

Slickenlines

Question 5

when a polished or grooved surface is covered with fibrous crystals of calcite, quartz, chlorite,hematite and their long axes oriented in the direction of the movement

Answer 5

Slinckenfiber

Question 6

Line formed where two surfaces intersects

Answer 6

Intersection lineation

Question 7

Consist of aligned ELONGATE mineral grains and grain aggregates including their pressure shadows

Answer 7

Mineral Lineation

Question 8

Penetrative lineation that form at boundaries between differing rock types and consist of corrugate or scalloped surfaces that results from the competence contrast from layer to layer

Answer 8

Mullions

Question 9

Penetrative lineation cosists of lenticular segmets of a layer that has been pulled apart and flattened in such a way that the layer is segmented. The layer beeing segmente is less ductile than the surrounding material

Answer 9

Boudinage

Question 10

Consists of segmented sausage shaped pieces of a single layer in which the lenticular segments parallel one another and results from extension in one direction

Answer 10

Ordinary Boudinage

Question 11

Formed when there’s two direction of extension and the resulting boudinage is a series of 3D blocks

Answer 11

Chocolate block or tablert boundinage
