Diorite?

Diorite is a type of igneous rock that forms when molten magma cools and solidifies deep within the Earth's crust. It's typically coarse-grained and has a speckled appearance, with a mix of light and dark minerals. The main components are plagioclase feldspar (usually white or light-colored) and darker minerals like hornblende or biotite. This gives diorite a salt-and-pepper look, distinguishing it from rocks like granite (which has more quartz) or gabbro (which is darker overall).
It’s pretty tough and durable, so it’s been used historically for construction and tools—think ancient Egyptian statues or Inca stonework. Geologically, it’s associated with subduction zones, where tectonic plates collide and magma gets cooking. If you’re into specifics, its silica content usually sits between 52-63%, making it "intermediate" between felsic rocks (like granite) and mafic ones (like basalt).
