Tertiary carbonate rocks

Tertiary carbonate rocks are sedimentary formations composed mainly of carbonate minerals like calcite and dolomite, formed during the Tertiary period (about 66 to 2.6 million years ago). They typically originate from the accumulation of biological materials such as coral, shell fragments, and marine organisms in warm, shallow seas. These rocks often form limestone or dolomite layers that can host important natural resources like groundwater and hydrocarbons. Their formation reflects historical environmental conditions of warm, tropical marine settings, making them significant for both geological study and resource exploration.
