In silicate minerals,tetrahedra may be coordinated to form ____________.
A) long one-dimensional chains
B) extensive two-dimensional sheets
C) massive three-dimensional frameworks
D) all of the above

Question

Quizplus · Accepted Answer

Silicate minerals can form long one-dimensional chains, extensive two-dimensional sheets, or massive three-dimensional frameworks depending on how their tetrahedra are coordinated. Examples of silicate minerals with these structures include chain silicates (such as pyroxenes), sheet silicates (such as micas), and framework silicates (such as feldspars).
