Marble Like Pattern Rock with Mica Elements found near Bedrock in Southern New Hampshire

[Golfer]

Never found a rock with this type of pattern before.  Almost looks marble like. Has some mica elements.  Found in the dirt pile dug near bed rock on the same property I have listed other rocks.  Still have a lot of area to search. Near former farm land with streams and game trails.  Thank you for your help identifying it.  Don’t have a scale with me so I can’t weigh it but it is heavy for its size.

Yes seems like biotite mica, quartz and lots of potassium feldspar, so this is an alkali feldspar granite, I think.

Definitely has quartz particles with mica books. The marble like areas feel very smooth. Rest of rock is very jagged. Thank you for your replies
