Yosemite National Park
The first time I visited Yosemite national Park was during a family trip to visit my aunt in San Jose California. It was a magnificent place. These enormous light color rocks are "granite", that what I thought when I first saw them. But taking a closer look, just like the picture above, this rock is actually diorite. Diorite and granite are closely related. Granite is composed mainly of quartz and feldspar while diorite is mainly composed of feldspar and other dark-colored minerals. They are both igneous rocks and are a common example of an intrusive igneous rock. They are called intrusive because they cooled and solidified beneath the surface. When that happens, the process is slow, slow enough for crystals to form. That's why intrusive igneous rocks have larger visible crystals.
This is truly a fascinating place. I can't wait to visit again and perhaps learn a bit more about Geology and igneous rocks.
