  “Earth’s mass is approximately 5.97×10^24 kg (5,970 Yg). It is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulphur (2.9%), nickel (1.8%), calcium (1.5%), and aluminum (1.4%), with the remaining 1.2% consisting of trace amounts of other elements.”
  
  That’s from Wikipedia.

  Apparently the most common mineral on Earth is Bridgmanite, which is “composed of magnesium, iron and silicon dioxide and it’s estimated to make up 38% of earth’s volume.” Have a look here: https://www.forbes.com/sites/davidbressan/2016/12/04/what-are-the-most-common-minerals-on-earth/#32c7f5bb615c
