Is this the correct way to cite a source using parenthetical documentation in my research paper?

Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits turn into coal. Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor. After millions of years the deposits end up in rock and sediment where oil is trapped in small places. Natural gas is a gaseous fossil fuel that is versatile and abundant. Like oil, it is formed from the remains of marine microorganisms. (Raum, 4-9)

In the parenthesis, I have put the author's name from the book,and the page numbers. Is this okay?

Thanks
