What makes metamorphic rocks like gneiss and quartzite especially valuable in the construction industry?

What determines a mineral’s crystal habit?

Volcanic islands that form in a line like the Hawaiian islands shown in the figure below have a pattern where the largest and most volcanically active island is at one end, while the islands become progressively smaller and older as you move farther away. What geologic setting does this pattern represent?  Source: U.S. Geological Survey (in the public domain)
