GEOLOGY 3:LAB/FIELDASSIGNMENTBenitoite mine and Los GatosCreek in Coalinga, California.
Late October• It took quite some time for me to decide where I wanted to head out to so I could do this Lab/Field assignment. I finally decided on going just a few miles out of Coalinga to go to two different places. • The California State Gem Mine • Los Gatos Creek• The California State Gem Mine is luckily co-owned by one of my best friends so he walked me through some of the camp, the history of the mine and camp, and showed me rocks such as Shist (aka Crossite) , Neptunite, and lastly, Benitoite.• Los Gatos Creek is a recreational camp site roughly half an hour out of Coalinga. When I visited the camp site, the creek wasn’t as filled as it is at times, but there were quite as few trees that I was able to get pictures of.
Los Gatos Creek and Surrounding Areas• Los Gatos Creek in located in the Diablo Range just outside of Coalinga.• Although it was quite challenging to find geological history of the creek, I did manage to find out Los Gatos Creek/Canyon was originally named Arroyo Pasajero.• The Arroyo Pasajero was occupied by Native Americans called the Chane, and was later settled by Spanish and, then, Mexicans. Los Gatos Creek
Angus Scientific Classification • Kingdom: AnimaliaThe Livestock • Phylum: Chordata Coalinga and its outskirts is • Class: Mammalia known for having many • Order: Artiodactyla open spaces that is used for • Family: Bovidae either farming or livestock. • Subfamily: Bovinae These cows seem to be Angus considering their color, lack of horns, and habitat. Originally, this type of cattle came from Northern Scotland and have apparently existed there before recorded history. All cattle are believed to have evolved from Aurochs, an extinct breed which used to reside in Europe, the middle East, India, and North Africa.

Livestock continued• Going up to Los Gatos Creek (also referred to as the canyon for places before or past the creek) there are mainly cattle and horses roaming around, so next I stopped to take a couple pictures of the horses. Horse Scientific Classification• When researching what type of breed these • Kingdom: Animalia two horses could be, I came upon a difficult • Phylum: Chordata fact: there are many types of breeds which • Class: Mammalia • Order: Perissodactyla could be black in color—many of which only • Family: Equidae have slight differences. • Genus: Equus• The origins of the black breeds varies from Russia, France, Czech Republic, and Italy.• The earliest known horse is the Hyracotherium, which lived about 55 million years ago in the woodlands of the Northern Hemisphere.

Wild Tarantulas On an earlier date before I had began my lab, I was once again on the road out to the canyon when something caught my eye on the road.

The California State Gem MineThe California State Gem Mine was founded in 1907 byJames Couch, but R.W. Dallas reigned control over themine.During the years 1912-1920, the mine was no longer beingworked on.Over the next decades, the mine was leased out to manyowners until it was sold to Dave Schreiner in 2005.From then on, they mine one of they rarest gems,Benitoite, and other gems.CA State Gem Mine
Benitoite, Shist (aka Crossite) , and Neptunite.• Benitoite is one of the rarest and expensive gems, and is also the state gem. Sizes of the gem are usually small but are hexagonal. They are most common a sapphire blue or white, and very slimly pink. On the hardness scale the Benitoite is a 6-61/2. It’s fracture is Crossite conchoidal and glows underneath an UV light. Neptunite• The Benitoite is found within the rock Shist, but better known as Crossite. It’s a rock that is rough in texture and has many fractures in which the Benitoite and Neptunite are found. Benitoite• Neptunite is black in color and opaque. It is brittle and the fracture is also conchoidal.
