@dalehileman,
The firt one is probably a granodiorite. (Granites have lrger feldspars and they are mostlly pink. This one hs more Ca than K in the feldspars. Granite is sort of a good term because its a grouping and granodiorite is a specific type of rock based upon crystal sizes, felldspar hemistry, prcent free quartz and evidence hether its volcanic or magmatic. The rock is special because, after it was emplaced, it was broken off its llens and then apparently rolled in a stream or dragged in a glcier. Its rounded pretty well. Glacially drug rocks usually have some flat "sanded sides" while stream rolled rocks are rounded more.
The second is definately a gneiss probably a hornblende gneiss.
Lota quartz and K Feldspar so its a fairly high egree of metamorphism
The third is definately a fossiliferous silty sandstone or sandy iltstone . Its not too cemented so it has undergone "partial hardening"The fossils are what we call a "Shell hash", which means its probably a death assemblage of dead shells that wre being tossed around and crunched in a moderate energy environment. There are Mercenaria (steamers) Lyropecten (Small scallops) and some other s I couldnt identify cause theyre mostly just chunks
Id say these were probably from Mid Cenozoic or later (Miocene to Pleistocene)
