Geological Review of the Rafflesia Trail, Near Kampung Jedip, Lojing Highlands: Inputs for a Nature-Based Tourism Site in Kelantan, Malaysia

A geological review was performed in the Rafflesia Trail, near Kampung Jedip,
in Lojing Highlands, Kelantan, Malaysia. This area is famous for its Rafflesia
and has become one of tourism attractions in the state of Kelantan. However,
the recent rampant agricultural activities have significant effects to the area. The
objective of this study is to give substantial geological inputs in terms of
geomorphology, lithology, structural features, and geohazard potentials in the
study area. Desk study was conducted by reviewing some literatures related to
the topic and the study area. Field work was organized during a scientific
expedition in January 2014 to collect data, samples, and photographs.
Geomorphologically, the study area is mountainous area which mostly consists
of mountain ridges and mountain valleys. Some fluvial features occur in the
study area, such as waterfalls, cascades, rapids, runs, pools, potholes, lateral
bars, and point bars. This area is composed of granitic rocks, mostly porphyritic
granite, and covered by superficial Quaternary deposits. The geological
structure that is commonly found in the study area is joints, where they divide
the rock body into large, roughly angular blocks, which is called as brecciation.
The potential geohazard in the study area is landslides, where some of them are
composed of soil only and some others are mixtures of rock and soil. This study
recommends this area should be supported as a sustainable nature-based tourism
site in Lojing Highlands, Kelantan.
