not to many people know this but a rather rare metamorphic rock is found in California it is called Eclogite it is one of the most beautiful I've seen. it is rare because of how it is formed. It is called an extreme metamorphic rock from the mantle. Like on who escaped from hell back to the surface. While eclogite is rare at the Earth's surface, it is very common at depth and has an important role in plate tectonics. When oceanic plates are subducted, their great thicknesses of basalt and gabbro change to eclogite and gain nearly 10 percent in density. This change in density makes subducted plates even more eager to descend.
This eclogite specimen from Jenner, California, was part of a subducting plate during Jurassic times, about 170 million years ago, when it formed. Much more recently, during the last few million years, it was raised and mixed into younger subducted rocks of the Franciscan complex. The body of eclogite is no more than 100 meters across today. It consists of high-magnesium pyrope garnet, green omphacite (a high-sodium/aluminum pyroxene), and deep-blue glaucophane (a sodium-rich amphibole). This is a good subject for a geological coctail party ;-)
Turquoise is another one,

Gravel, sand, and crushed stone are HUGE exports in California, so they count as resources.

Here you go. Look at the bottom of this website where it lists many natural resources in California.
