Two different examples of the same thing

Questions:
1. What general mineral name would be given to these specimens? (i.e. if it is rose quartz then say quartz)
2. What is the name given to this special formation?
3. How might these specimens have formed?
4. Which property causes these formations? (there are multiple answers to this)

I might have butchered this lol: 1. Feldspar? (Potassium Feldspar?)
2. Perthite?
3. Exsolution. (A solid solution of a grain of alkali feldspar is cooled and is composed between K-Feldspar and Albite)?
4. Cation size?

1, 2, 3, are correct
for 4 I was looking more for miscibility but there are multiple answers so you got all correct :)
