Our goals

Learning how to describe the structures of rocks and

regions.

To understand the movements that accompanied

development of the structures.

To interpret structures and systems of structures in

relation to mechanics, tectonics, and geologic history.

What is geologic structure?

Geologic structure is a geometric feature in rock whose

shape, form, and distribution can be described.

Geologic Structure:

Primary Structure. Acquired in the genesis of a rock

mass.

Dike, Graded Bedding, Foliation, etc.

Secondary Structure. Result from later deformation of

the primary structures.

Faults, Fold, Joint, etc.

Structural Analysis

1. Descriptive analysis

Recognizing and describing structures and measuring

their locations, geometries, and orientations.

2. Kinematic analysis

The movement paths that rocks or parts of rocks have

taken during transformation from the undeformed to the

deformed state.

3. Strain analysis

The development of mathematical tools for quantifying

the strain in a rock. Distortion (changes in shape) and

Dilation (change in size).

Adhari, M.R., Teknik Geologi Unsyiah

4. Dynamic analysis

The development of stress and its relation to deformation

5. Mechanism analysis

The study of processes on the atomic scale to grain scale

that allow structures to develop.

6. Tectonic analysis

The study of the relationship between structures and

global tectonic processes.

Adhari, M.R., Teknik Geologi Unsyiah

Descriptive analysis

Strain analysis

Dynamic analysis

For the results of a structural analysis to be

interpretable, the scale of our analysis must be taken

into account.

For example, a bed of sandstone in a single outcrop in a

mountain may appear to be undeformed. But the outcrop

may display only a small part of a huge fold that cannot

be seen unless you map at the scale of the whole

mountain.

Scale of observation :

Microscale : features that are visible optically at the scale

of thin sections (electron microscope).

Mesoscale : features that are visible in a rock outcrop, but

cannot necessarily be traced from outcrop to outcrop.

Macroscale : features that can be traced over a region

encompassing several outcrops to whole mountain ranges.

Megascale : continental-scale deformational, such as the

movements of tectonic plates over time.

Adhari, M.R., Teknik Geologi Unsyiah

Each scale of observation has its own set of tools :

Microscale : Optical and electron microscopes are

used.

Mesoscale : recognition and description of rocks

requires a set of eyes, a hammer, a compass, and a

hand lens.

Macroscale, Megascale : Satellite imaging may be

used for observations.
