Question

Quizplus · Accepted Answer

For a mineral to cement rock grains together, it must be dissolved in water to be able to fill the pores and spaces between the grains and solidify to form a cementing material. The type of bonding between the cement mineral and the grains is not as important as the ability to fill in the gaps between the grains. Similarly, the similarity in type between the cement mineral and the grains is not a requirement for cementation to occur.
