INTRODUCTION
The geological history is an important area of interest for geologists. Geologists are
known to use various principles in order to find the sequence and origin of occurrence of events
(Harris, 2014). The report will explain the sequence and origination details of geological events
which occurred in the hypothetical landmass called Kelburnia. The report will use various
principles to determine the age and sequence of rocks and for identification of events.
PRINCIPLES OF GEOLOGY
For analysing the geological history of events at Kelburnia, the following principles are
used:
Original horizontality principle: According to this principle, sediments are deposited as
horizontal beds. The same principle is demonstrated in deposition of non-marine and marine
sediments as well.
Superposition principles: As per this principle, the sedimentary rocks can be considered as
vertical time line in which the layers below it is considered as older to it and the layers above it
are considered as younger than it.
Principle of Faunal succession: This principle states that the appearance and the structure of
fossils within sedimentary rocks can be used as the criterion to predict the age of the geological
component in which fossil is present (Richardson and et.al., 2015).
GEOLOGICAL HISTORY OF KELBURNIA
The geological sequence of the events in Kelburnia landmass occur in the following
sequence. The history of their occurrence is based on the principles of geology.
Metamorphic, granite and conglomerate rocks origin
Granite is an igneous rock and has a granular texture. The occurrence of Granite in
Kelburnia was caused when liquid rocks known as magma were pushed upwards from the
interior of the earth. This is the reason they are considered as the oldest rocks of Kelburnia.
When magma is pushed upwards then it undergoes into intrusion process which is followed by
cooling and hardening. When magma cools down then, it again undergoes a process called
fractional crystallization. This process enhances the constituent elements of Granite such as
