Jayawijaya Mountains is the name for the mountain range that extends lengthwise in the center of the province of West Papua (Indonesia) to East Papua (Papua New Guinea) in Papua Island. Rows of Mountains which have some of the highest peak in Indonesia was formed by the removal of the sea floor thousands of years ago. Even at the height of 4800 masl, fossilized sea shells, for example, can be found in limestone and clastic rocks that are in the Jayawijaya Mountains. Therefore, besides being a heaven for hikers, mountain paradise Jayawijaya also a world geological researchers. Jayawijaya Mountains are also the only mountain in Indonesia, which has a peak covered with eternal snow.
The history of the formation of Jayawijaya Mountains
According to geological theory, originally the world only have a continent named Pangea at 250 million years ago. Continent Pangaea split into two to form the continents Laurasia and the Eurasian continent. Eurasian continent burst back into Gonwana continent that later would become the mainland of South America, Africa, India, and Australia.
Precipitation is very intensive in the continent of Australia, plus the occurrence of plate collision between the Indo-Pacific plate with the Indo-Australian on the seabed. Plate collision resulted in the island arc, which also became the forerunner of the islands and mountains in Papua.
As a result of the appointment process is ongoing, sedimentation and tectonic events along under the sea, within a period of millions of years to produce high mountains as you can see today. Evidence that the high mountains of Papua Island and its never been part of the deep seafloor can be seen from the fossil remains in rocks Jayawijaya.
