Felsic rocks are generally relatively low density\u2014for a rock\u2014and light in color because they are made from whitish minerals rich in silicon and aluminum. Half Dome in California is made of granite that is a felsic rock. Mafic rocks, in contrast, are relatively high in density and dark in color because they contain minerals rich in iron and magnesium; Giants Causeway in Northern Ireland is made of basalt, which is a mafic rock.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-06-earth-rock-solid-canada-australia-clues.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Earth&#8217;s rock-solid connections between Canada and Australia contain clues about the origin of life<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The rocks at the surface of the modern Earth are broadly divided into two types: felsic and mafic.
