The northern part of the island is dominated by the Panian Coalfield, the largest of three coalfields on the island. Most of the coal is used for energy generation in the Philippines, with some exported to India and China. The Panian coalfield is being mined using open-pit methods. The rock and soil above the coal layers (or seams) is known as overburden. Overburden is removed from the pit and heaped into piles, several of which ring the northern half of the pit. Several of the dark coal seams are visible along the sunlit southern wall of the pit (these may be more visible in the larger image version). Plumes of sediment from the overburden piles enter the Sulu Sea along the northern and eastern coastline of the island. The Semirara coalfields formed from 12–23 million years ago along what was then a coastal plain—similar to the current geologic environment of the southeastern Gulf Coast of the United States. Organic materials were deposited in sequences of sandstone and mudstone, which were then covered by limestones as the environment became progressively more marine. Over geologic time, increased pressure from the overlying rocks changed the layers of organic material into coal. Download Packaged File.
