2.  Site Location
 Coalinga Oil Fields History
 Geological History
 Rock Samples
 Geological Features
 Plant Samples
 References

3.  Near Coalinga, CA
 Took dirt road to a dirt
lot, walked up a path
full of weeds and rocks,
led to big hills, walked
throughout the fields

4.  In 1865-Interest in oil inspired an oil rush
 The interest started die out because of shipping
problems
 In 1890-second oil rush happened because coal mines
had little value
 Coalinga was the third largest shipping point for
railroads in California-mostly all connected to oil
production
(“History of Coalinga, 2011”)

5.  On May 2,1983 there was a
earthquake with a
magnitude of 6.4
 This earthquake was
triggered by an 0.5-meter
uplift of Anticline Ridge
northeast of Coalinga
 Triggered rock falls and
rockslides
 Pumping units, storage
tanks and pipelines from oil
fields were destroyed
(“California Earthquake Map
Collection, 2005”)

6.  I believe this rock is a
Mudstone-made of
hardened mud
 The rock was found in a
creek, which was made
from water and mud,
known as a sedimentary
rock
 I thought it was a
claystone, but the stone
was not fully made by  The rock is grey, hard to
clay break, solid, hard to scratch and
(“MUDSTONE, 1995”) is surrounded by other pieces of
mudstones

7.  This a type of
sedimentary rock because
it was found in a mud
area along a small creek
 It’s a claystone- rock
made from clay, turns
hard, doesn’t get soft
when touched by water
(“Claystone, 2011”)
 I thought it was a  Rock is orange with white,
shows cracks, piece of outer
siltstone, but doesn’t layer is broken off, hard clay
show layers rock

8.  Sandstone forms where
sand is laid down and
buried
(“Sandstone, 2011”)
 The sandstone is known
to be a sedimentary rock
(“Sandstone, 2011”)
 The sandstone is very
similar to the Quartzite
stone- which is a  Found the stone in the dirt, the
metamorphic rock surface is covered in dirt,
(” Quartzite, 2011”) cracks all over the side, color
pink, stone has different
angles.

9.  As you can see from the
image, life is hard to
find during this season
 It is like a desert climate
 Animals don’t come
out, plants are dead or
almost dead
 You have to walk all
over the hills to find any
form of plant

10.  The Yellow Coneflower is also
known as the Ratibida Pinnata
 Grows best in full sun to
partial shade-medium to dry-
medium soil conditions
 They have stiff and rough
feeling coarse leaves, yellow
flowers that have droopy soft
yellow rays
 The cone-like green centers
eventually change dark brown
 Insects like butterflies and
bees are attracted to this  Some of these flowers are half
flower dead-exposed to too much
heat, and some are alive, the
(“Ratibida pinnata, 2011”) stems are a mixture of brown
and green

11.  The Coneflower is called Echinacea
 The Echinacea is self evolutionary, it blends into its
environments , several different kinds of Echinacea
 Types of Echinacea
◦ After Midnight: Purple-Red, bloom July-August
◦ Bright Star: Purplish-Pink, bloom July-August
◦ Coconut Lime: White, bloom July-August
◦ Coral Reef: Orange, bloom mid-late summer
◦ Doubledecker: Pink, bloom during summer
◦ Fancy Frills: Pink, bloom during summer
◦ Fatal Attraction: Purplish-Pink, bloom during summer
◦ Firebird: Red-Orange, bloom Mid-Late summer
◦ Flame Thrower: Orange-Yellow, bloom Mid-Late summer
(“Echinacea, Coneflower, 2009”)

12.  This tree is hardy and thrives
in warm, wet winters and dry
summers
 It’s a diverse tree with more
than 700 species
 Grow from 30 to 200 feet
 They could produce white,
pink, red and yellow flowers
 It’s leaves produce a waxy oil
that prevents water loss in hot
weather
 It is used to reduce
inflammation and fever
 Some of the leaves are dying,
(“Eucalyptus Tree, 2011”)
pieces of the tree are falling off
and there was a lot of bugs flying
around it.

13.  The Eucalyptus tree could be found in regions of
South America, South Africa and India
(“Eucalyptus Tree, 2011”)
 It is one of the oldest trees on earth that dates
back to about 50 million years
(“Eucalyptus Tree, 2011”)
 Evolved from rainforest precursors because of
changes in landscape, soils and climate
(“About Eucalypts,2011”)
 They are native to Australia
(“Eucalyptus Tree, 2011”)
 The essential oil can be toxic in large amount
(“About Eucalypts,2011”)

14.  Most have yellow, red or
purple flowers
 All have flat, fleshy pads
that look like large leaves
 Pads are modified
branches or stems
 Stems serve as water
storage, flower
production and
photosynthesis
 It is found in North
America  The Cactus were small, had red
(“Prickly Pear Cactus, 1996”) flowers, were squeezed together
and had long spines

15.  Represents about a dozen species of the Opuntia
(“Prickly Pear Cactus, 1996”)
 There has been medical interest in this Cactus
 Pectin contained in the pulp lowers levels of bad cholesterol
 Fibrous pectin in fruit may lower diabetics’ need for insulin
 Both fruits and pads of this cactus are rich in slowly absorbed
soluble fibers that help keep blood sugar stable
(“Prickly Pear Cactus, 1996”)
 The cactus can be cooked into jams and preserved down
into a syrup as a base for jelly
(“Prickly Pear Cactus,1992”)
 The sap from the pads can be used in first aid similar to the
Aloe Vera plant
(“Prickly Pear Cactus,1992”)
