GEOLOGY

The Municipality of Iba is characterized by a coastal plain and a mountain range on the eastern region. The mountainous region is composed of ultramatic rock overlain by marine sedimentary deposits. In the lowland, recent alluvial deposits take place.

The litho-stratigraphy of the town corresponds to three different formations ranging from; Pre-tertiary rock, Santa Cruz shale to recent alluvial deposits.

The pre-tertiary rocks consist of a complex of intrusive ultramatic rock which form the basement complex. Gabro, dunite and saxonite are the main constituents of these rocks.

The Santa Cruz shale formation consists of sandstone and conglomeratic shale of Upper Miocene Age overlying the lower most slopes of the basement rocks. Its thickness may reach 200 meters below the alluvial deposits. This formation, according to the experts, have negligible water bearing characteristics.

The recent alluvial deposits mainly composed of sands and other alluvial sediments which cover the alluvial plain and coastal areas. These sand deposits have a thickness that ranges from 10 meters to 30 meters.

These alluvial deposits may be divided into two types; Swampy silty-clayey muds extending roughly north east of the town and the recent sand and gravel deposits taking place southwestward.
