Bohol Geography: Geologic Formation

The geological formation of Bohol dates back millions of years ago, during the Late Jurassic Period, around 160 to 145 million years ago. At that time, the majority of the island was still underwater, with only Mt. Malibalibod in Ubay and its nearby area in Alicia emerging above the sea.

Around 66 million years ago, during the end of the Cretaceous Period, the northern part of Bohol began to gradually rise.

Volcanic activity played a significant role during this time, leading to the deposition of multiple layers of volcanic rock across the region.

As landmass increased, Bohol's geology started to take shape during the Paleogene Period, around 60 million years ago. Diorite, an igneous rock, was introduced into the Talibon area during this period.

Between the Eocene and Oligocene epochs, Bohol's geological development paused for millions of years.

However, during the Miocene epoch, approximately 23 million years ago, the island's geologic evolution resumed.

Uplift and volcanic activity contributed to the deposition of limestone and the emergence of andesite, another volcanic rock. At this point, only the eastern half of the island was above water.

Around 5 million years ago, the southeastern portion of Bohol started to rise from the ocean, gradually revealing more of the island's landmass.

From the late Pliocene to the Pleistocene, approximately 3.6 to 1.8 million years ago, the remaining submerged areas of Bohol emerged, shaping the island into its present form.
