Consider the following statements with reference to Feldspar mineral:
1. Half of the earth's crust is composed of feldspar
2. It has light cream to salmon pink colour
3. Magnesium is a common element in all types of feldspar
Which of the statements given above is/are correct?

Feldspar is the most abundant mineral group, making up about half of the Earth's crust. Thus, statement 1 is correct.

Feldspar minerals typically exhibit colours ranging from white and light cream to salmon pink. Thus, statement 2 is correct.

Feldspars are primarily aluminosilicates of potassium, sodium, and calcium. Magnesium is not a common element in feldspar. Thus, statement 3 is incorrect.

Therefore, only statements 1 and 2 are correct.

Answer: 1 and 2 only
