Webgranite. All igneous rocks are made of the same major elements, but elemental ratios vary. The most significant variations are the amounts of silica (SiO 2) present (see table). Most igneous rocks contain between 45 and 70 wt% silica. They range from lower-silica basalt and gabbro to higher-silica rhyolite and granite.
