• 😀 The geopark is divided into two key areas: the geological nature reserve (Karangsambung) and the karst landscape (KBA Gombong Selatan).
• 😀 Karangsambung Karang Bolong is an important site for studying geological history, especially evidence of ancient subduction fossils between the Australian and Sunda Eurasian plates.
• 😀 The region features a wide range of rock types, including sedimentary, metamorphic, and igneous formations, each with distinct geological histories.
• 😀 Various rock types in the area serve as evidence for tectonic plate theories, particularly in understanding the process of plate tectonics.
• 😀 The region provides an opportunity to observe rock formations like breccia and basalt lava, which are key elements in the study of geological history.
• 😀 Researchers can find rock layers with distinct features, such as foliated metamorphic rocks, indicating pressure-induced changes from tectonic activity.
• 😀 Karangsambung is recognized for its geological significance, as it contains rocks that originated from oceanic crust, pointing to its history as a former seabed.
• 😀 The site is also home to significant fossil evidence, including radiolaria, and unique structures like pillow basalts formed from lava interacting with water.
• 😀 The Geopark is an ideal location for geology students and researchers, facilitating practical learning and exploration of Earth's tectonic processes.
• 😀 The Kebumen region, through its National Geopark, is aiming for UNESCO Global Geopark status, which would bring international recognition to its geological heritage.

Q & A

What is the main geological feature of Kabupaten Kebumen discussed in the script?

The main geological feature is the Karangsambung Karang Bolong National Geopark, which is known for its significant geological history, including evidence of ancient subduction between the Australian and Sunda-Eurasian plates.

What is the size and scope of the Karangsambung Karang Bolong Geopark?

The geopark covers an area of 543.599 km², spanning 118 villages and 12 sub-districts, divided into two main zones: the geological nature reserve area and the karst landscape area in Gombong Selatan.

Why is Karangsambung Karang Bolong significant for geological studies?

It is significant because it holds important geological evidence, such as ancient subduction fossils and various rock formations that illustrate the tectonic plate theory and the region's geological history.

What type of rock formations can be found in Karangsambung Karang Bolong?

The region features various rock formations, including sedimentary rocks, metamorphic rocks, and volcanic rocks, each offering insights into the area's tectonic history.

What does the presence of metamorphic rocks in Karangsambung Karang Bolong indicate?

The presence of metamorphic rocks suggests that the area was once part of the Earth's basement, formed under high pressure and temperature conditions, and offers evidence of deep geological processes.

What is the significance of the black, pillow-like lava structures found in the geopark?

These pillow-like lava structures form when lava erupts underwater, and they are important because they represent ancient underwater volcanic activity, providing evidence of past oceanic environments.

What role do the sedimentary rocks play in understanding the area's history?

The alternating layers of sedimentary rocks, such as red clay and limestone, indicate that the area was once submerged in shallow seas, offering a glimpse into the past marine environments.

How does Karangsambung Karang Bolong contribute to the study of plate tectonics?

The geopark serves as an ideal location for studying the plate tectonics theory, with its visible rock formations providing clear evidence of the movement and interaction of tectonic plates in the region.

What educational benefits does the geopark offer to students and researchers?

The geopark provides an excellent natural laboratory for geology students and researchers, offering hands-on learning opportunities about earth processes, plate tectonics, and geological formations.

What is the potential future recognition for Karangsambung Karang Bolong, and why is it important?

Karangsambung Karang Bolong is being proposed for UNESCO Global Geopark status, which would increase its international recognition and highlight Indonesia's rich geological history, potentially attracting global attention to the region.
