Had some great input from a follower noting that she believes what I noted as granite (also said marble a couple times :) is “granitoid” and that she believes what I thought was weathered cement but noted it may be pudding stone is indeed weathered cement :). Love the input and love learning. Thanks! Granitoids are a larger family of rocks that includes granite, and they differ in a few ways: Composition Granitoids are made up of quartz and feldspar in varying proportions, and may also contain mica or amphibole. Granite is a type of granitoid that's rich in quartz and alkali feldspar. Origin Granitoids are formed by partial melting of the crust, while granite forms when magma cools below the Earth's surface and is then uplifted. Classification Granitoids are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (QAPF classification). Uses Granite is used in buildings, bridges, paving, monuments, and more, both indoors and outdoors. Granitoids are an important part of the Earth's continental crust and help us understand crustal growth and tectonic evolution. Granitoids are the most abundant rock type in the continental crust. However, there's no single classification scheme that's widely used because the same mineral assemblage can be achieved by different processes.

Looks like a great Wisconsin beach to rock hunt. Beautiful finds. Like the washed and close ups at the end. I also rock hunt in Wisconsin 😊
So many amazing beaches to explore. I love getting to go on adventure and hunt for treasures at the same time :). Happy hunting!
