Rock found in lake

0 votes

Hi. I found this rock in a lake and I would love to know what you think it is. The white looking part is like a shiny glass looking thing and its all over the rock when you shine light on it.  :)

The shiny bits are probably mica shards, or even small pieces of quartz crystals, the rocks themselves look like sedimentary rock like sandstone and limestone.
