Here's a breakdown:

* Felsic rocks are light-colored and rich in silica (SiO2). Examples include granite, rhyolite, and some types of gneiss.

* Intermediate rocks have a composition between felsic and mafic. Examples include diorite and andesite.

While these are the most abundant, you can also find some mafic rocks in the continental crust, which are dark-colored and rich in magnesium and iron. Examples include basalt and gabbro.

It's important to note that the continental crust is not uniform. It's a complex mosaic of different rocks formed over billions of years through various geological processes like:

* Volcanism: Eruptions of magma create igneous rocks.

* Metamorphism: Existing rocks are transformed by heat and pressure.

* Sedimentation: Erosion and weathering break down existing rocks, and these fragments are deposited and lithified into sedimentary rocks.

So, while felsic and intermediate rocks dominate, the continental crust is a diverse and fascinating patchwork of different rock types.
