Does slate have foliation
WebA rock does not need a specific mineral composition to be called "schist." It only needs to contain enough platy metamorphic minerals in alignment to exhibit distinct foliation. This texture allows the rock to be broken into thin slabs along the alignment direction of the platy mineral grains. ... Slate is has a dull luster, it can be split ... WebSep 10, 2024 · There is one foliation type that is defined by the alignment of minerals that are too small to see, yet the foliation can still be visible. This type of foliation is only seen in the metamorphic rock called slate; slate forms by the low temperature and low-pressure alteration of a shale protolith.
