The Meratus Mountains are not just a row of hills and valleys. It is a silent witness to long and complex geological journeys that have resulted in unique landscapes, abundant biodiversity, and cultural richness that are inextricably intertwined with nature. Understanding the geology of this area is key to appreciating the beauty and uniqueness of the mesmerizing Meratus landscape.
Meratus Mountains, a Destination Vacation with a Long and Winding Geological History
The formation of the Meratus Mountains is the result of a series of tectonic events that lasted for millions of years. The core of these mountains is thought to have formed in the Late Cretaceous to Early Tertiary Period, about 100 to 65 million years ago. At present, the collision between the Pacific Plate and the Eurasian Plate, which involves the subduction (infiltration) of the oceanic crust under the continental crust, triggers the uplift and deformation of ancient rocks.
The Meratus bedrock is dominated by metamorphic rocks such as schist, gneis, and phylate, which are sedimentary and igneous rocks that have undergone changes due to high pressure and temperature deep below the earth's surface. Intrusions of igneous rocks such as granite and diorite have also been found, signaling ancient magmatic activity that accompanied the process of mountain formation.
Over time, erosion and weathering by water, wind, and temperature changes gradually carved the landscape of Meratus into its present form. Winding rivers divide the mountains, forming steep valleys and deep canyons. The difference in rock resistance to erosion results in diverse topographic formations, ranging from sharp peaks to sloping slopes.
The Uniqueness of the Geological Structure of Meratus
One of the unique geologies of the Meratus Mountains is the existence of ophiolite paths. Ophiolite is a fragment of the oceanic crust and upper mantle that was exposed on land due to tectonic processes. At Meratus, this phyolite path stretches relatively long and consists of rocks typical of the oceanic crust such as ultramafic rocks (peridotite, serpentinite), gabbro, and pillow-coated basalt.
The presence of these ophiolites provides important information about the tectonic history of this region, showing that the Meratus region was once part of the ocean floor that was later lifted and became part of the continent. The ultramafic rocks in the phyolite also have a unique mineral content, which in turn affects the type of soil and vegetation that grows on it.

In addition to ophiolites, Meratus also holds significant potential mineral resources, including chromium, nickel, and gold ores that are often associated with ultramafic rocks. The existence of this resource has attracted mining activities in several mountainous areas, which on the one hand contribute to the economy but on the other hand also pose challenges related to environmental management.
Mesmerizing Landscape Morphology
The complex interplay between geological history, rock structure, and geomorphological processes has resulted in a highly diverse and stunning landscape of the Meratus Mountains. Some of the characteristic morphological features of this area include:
- Steep and Dense Peaks: The core of the mountains is often characterized by towering peaks with steep slopes, covered by dense tropical rainforest and high biodiversity. The highest peak in Meratus is Mount Halau-Halau.
- Deep and Winding Valleys: Millions of years of river erosion have carved deep and winding valleys between the mountains. These rivers are a natural transportation route and a source of water for the local community.
- Charming Waterfalls: The difference in height and resistance of the rocks results in many beautiful waterfalls in different parts of Meratus. This waterfall not only has aesthetic value but also becomes a habitat for various types of aquatic flora and fauna.
- Unique Rock Formations: In some places, selective erosion has formed unique and interesting rock formations, such as cliffs, small karst caves, and rocks with distinctive weathering patterns.
- Plateau and Plato: In some parts of the mountains, especially in the south, there are relatively flat plateaus and plateaus. This area is often used for agriculture and plantations.
The Influence of Geology on Biodiversity
The geology of the Meratus Mountains indirectly plays an important role in shaping the region's rich biodiversity. The type of rocks and minerals in the soil affects soil fertility and nutrient availability for plants. The presence of ultramafic rocks, for example, results in soils with a higher content of heavy metals, which affects the types of plants that can grow on them and in turn affects the types of animals that live in those ecosystems.
The topographic variations produced by geological processes also create a wide variety of microhabitats, from humid valleys to dry slopes, from lowland forests to highland forests. These habitat differences allow different types of plants and animals to adapt and multiply, thereby increasing overall biodiversity.
A Paradise of Flora Diversity
The forests of the Meratus Mountains are a storehouse of plant diversity. Various types of lowland and mountainous tropical trees thrive here, forming a vast green canopy. Giant trees such as ironwood (Eusideroxylon zwageri), meranti (Shorea spp.), and keruing (Dipterocarpus spp.) dominate the landscape, providing support for plant and other animal life.
In the lower layers of the forest, various types of epiphytic plants such as orchids, ferns, and mosses adorn the trunks and branches of trees. The diversity of orchids in Meratus is very high, with various endemic species that have charming colors and shapes. In addition, various types of traditional medicinal plants can also be found in the forests of Meratus, which have been used by the local indigenous people for centuries.
Not only trees and epiphytes, Meratus is also rich in various types of underplants such as herbs, shrubs, and lianas. Some of them have important economic value, such as rattan and bamboo, which are used for handicrafts and building materials. The existence of these various types of plants not only enriches the natural beauty of Meratus but also plays an important role in maintaining the balance of the ecosystem.
Endemic and Interesting Fauna
The biodiversity of the Meratus Mountains is not only limited to plants but is also reflected in the richness of its fauna. The region is home to a wide variety of mammals, birds, reptiles, amphibians, fish, and invertebrates, including many endemic species found nowhere else in the world.
Some of the charismatic mammals that inhabit Meratus include Bornean orangutans (Pongo pygmaeus morio), proboscis monkeys (Nasalis larvatus), Bornean gibbons (Hylobates muelleri), and various types of forest cats such as woodpecker (Neofelis nebulosa). The existence of these primates shows the importance of Meratus as a key habitat for endangered species.
The bird world in Meratus is also very rich and diverse. Various types of birds endemic to Borneo such as hornbills, hornbills, and various types of songbirds can be found in these mountain forests. The melodious sounds of these birds are an inseparable part of Meratus' natural symphony.
In addition to mammals and birds, Meratus also holds an interesting diversity of reptiles and amphibians. Different types of snakes, lizards, geckos, tree frogs, and toads inhabit various habitats in this region. Some of them have unique colors and patterns, becoming a special attraction for researchers and nature lovers.
The rivers and other bodies of water in Meratus are also home to a wide variety of freshwater fish, including several endemic species. The existence of these fish is important for the balance of aquatic ecosystems and also as a source of protein for the local community.
The Relationship of Geology to Human Life and Local Culture
The indigenous peoples who inhabit the Meratus Mountains have coexisted with nature for centuries. They have in-depth knowledge of their surrounding environment, including the sustainable use of natural resources. The geology of the region directly influences their lives and culture in various aspects:
