schist-gneiss
The mica minerals are sheet silicates with a three-layer sheet structure and with either K+ or Ca++ and Na++ between the layers. The micas are varied in color, with low harness and perfect basal cleavage. They are important minerals of metamorphic and igneous rocks. Both schist and gneiss are metamorphic rocks. Slate is a sedimentary metamorphic rock-but sandstone is sedimentary,limestone and sandstone are sedimentary, and shale-limestone are sedimentary.

Mica is a aluminium silicate group of minerals which include muscovite, biotite and fuchsite.
it is primarily found in igneous rocks near the granitic composition
so in answer to your question
schist and gneiss being metamorphic/deformed forms granitoids will contain mica. but in addition it is also a very risistant mineral and is found in sediments, so sandstone will also contain mica if from right province. slate being of metamorphic grade may also contain mica if close to the mica schist facies.
simply for a school answer though, gneiss -schist (the correct way round) seems to be your pair

Granite and rhyolite. SandStone(i know this is right) - slate i think
