Durian Perangin is a place famous with its beautiful view and hence attracted a lot of tourists and some families to come here for a family day during weekends.
As for the geologists, it is also one of the interesting location to look for metamorphic and igneous rocks. There are two types of metamorphic rock which is foliated metamorphic rock and non-foliated metamorphic rock. The one that can be found here is a non-foliated one with name hornfel. The rocks undergo metamorphism under high pressure and temperature, therefore it is hard to break.
A few characteristics of metamorphic rock:
- Fine-grained
- Dark in color
- Massive (non-foliated)
- 'Chipping sound' when hitted which indicates its hardness
- Bad porosity and permeability
Drilling usually stops when hornfel is met. Hornfel is said to be the basement of a petroleum system where no oil and gas can be found.
