Basalt Rock Deposit In Philippines

Extrusive igneous rock, also known as volcanic rock, is formed by the cooling of molten magma on the earth's surface. The magma, which is brought to the surface through fissures or volcanic eruptions, rapidly solidifies.Hence such rocks are fine-grained or even glassy.Basalt is the most common extrusive igneous rock and forms lava flows, lava sheets and lava plateaus.

The alkaline rock series found in many rifting areas are very unusual, and far less common than the basalt - andesite - dacite suites found in other environments. We here discuss how some of these unusual magmas might have come into existence.

SMI selected open-pit mining as the only viable method due to the nature and geology of the deposit. Mining activities were planned to include preparation of the site, drilling and blasting of the ore and waste rock. Ore and waste rock was supposed to be extracted using large mechanical shovels, excavators and trucks.

- Stump of rock formed when magma which solidified inside a vent (plug) is exposed by denudation. • A volcano is first formed. • Lava on the sides of the volcano is eroded fast due to cooling fast. • The lava in the vent which is hard due to slow cooling is exposed forming a stump of rock e.g. Peaks of Mt. Kenya, Rangwa Hill and Tororo Rock.
