Engineering Geology Questions and Answers – Classification of Joints – 01

This set of Engineering Geology Multiple Choice Questions & Answers (MCQs) focuses on “Classification of Joints – 01”.

1. The classification which is not considered under study is ___________
a) Spatial relationship
b) Number of joints
c) Geometry
d) Genesis
View Answer

Answer: b
Explanation: Joints have been classified on the basis of spatial relationships, geometry and genesis.

2. The type of joint which can be measured and mapped easily is ___________
a) Systematic joints
b) Non-systematic joints
c) Irregular joints
d) Homogenous joints
View Answer

Answer: a
Explanation: Systematic joints show a distinct regularity in their occurrence which can be measured and mapped easily.

3. Example of systematic joints are ___________
a) Columnar joints
b) Mural joints
c) Sheet joints
d) Columnar and mural joints
View Answer

Answer: d
Explanation: Systematic joints occur in parallel or sub-parallel joint sets that are represented in the rocks at regular intervals. The columnar joints and the mural joints are examples of regular or systematic jointing.

4. How many groups are classified based on the presence of regularities?
a) 2
b) 3
c) 5
d) 4
View Answer

Answer: a
Explanation: All joints are divided into two main groups on the basis of presence or otherwise of some regularity in their occurrence.

5. Which type of rocks are classified based on geometry?
a) Pseudo-stratified
b) Stratified
c) Non-stratified
d) Anisotropic
View Answer

Answer: b
Explanation: In stratified rocks, joints are generally classified on the basis of the relationship of their attitude with that of the rocks in which they occur.

6. How many types are further classified based on geometry?
a) 2
b) 4
c) 3
d) 5
View Answer

Answer: c
Explanation: Under the classification based on geometry, three types are recognized: Strike joints, dip joints, oblique joints.

7. The type of joint not studied under the geometry as basis is ___________
a) Strike joints
b) Dip joints
c) Hade joints
d) Oblique joints
View Answer

Answer: c
Explanation: Only three types of joints are studied under the classification of joints on the basis of geometry; strike joints, dip joints and oblique joints. Hade joint is not a type of joint.

8. What is the other name for diagonal joints?
a) Dip joints
b) Strike joints
c) Sheet joints
d) Oblique joints
View Answer

Answer: d
Explanation: Oblique joints are those joints where the strike of the joints is at any angle between the dip and the strike of the layers. These layers are also called diagonal joints when they occur midway between the dip and strike of the layers.

9. Joints parallel to bedding planes are called ___________
a) Strike joints
b) Bedding joints
c) Dip joints
d) Oblique joints
View Answer

Answer: b
Explanation: In stratified rocks, some joints ma develop essentially parallel to the bedding planes. These are simply referred as bedding planes.

10. Non-systematic joints occur at random in the rocks.
a) True
b) False
View Answer

Answer: a
Explanation: Non-systematic or irregular joints appear at random in the rocks and may have incompletely defined surfaces. In many cases, these are related to the systematic joints in that these occur between them.
