The most common mineral element in Earth's crust is Silica, in a  percentage of 27 point seven percent, the second most abundant  mineral is Aluminum, with an eight percent â¦ and third Iron, with a  five percent.Answered. In Earth Sciences.xygen and silicon are the two most common ELEMENTS in the Earth's crust. These two elements bond to create silicates, which are the most abundant GROUP OF MINERALS in the Ear â¦ th's crust.
This list of minerals and specific articles about each mineral species are all focused on minerals as they naturally occur within rocks and sediments. More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars (plagioclase (39%) and alkali feldspar (12%)). Other common silicate minerals are quartz (12%) pyroxenes (11%), amphiboles (5%), micas (5%), and clay minerals (5%). The rest of the silicate family comprises 3% of the crust.
