  • 1. Field Assignment: Part 1 By: Margarita Estrada
  • 2. Tranquillity, California <ul><li>Tranquillity is a census designated place that lies north of Fresno, in Fresno County. </li></ul><ul><li>“ According to the United States Census Bureau, the CDP has a total area of 0.6 square miles (1.6 km2), all of it land” with an elevation of 164 feet. </li></ul><ul><li>With a population of 799 this little town still managed to be on the U.S. Geological Survey Map. </li></ul><ul><li>&quot;Tranquillity, California.&quot; Wikipedia, the Free Encyclopedia . 4 Oct. 2011. Web. 20 Nov. 2011. <http://en.wikipedia.org/wiki/Tranquillity,_California>. </li></ul>
  • 3. What's an Igneous Rock? <ul><li>Igneous rocks are one of the oldest types of rock. The word “igneous” comes from the Greek word Fire . </li></ul><ul><li>Why fire? Simple. When temperature deep inside the earth starts to rise magma also starts to rise and as it reaches the surface its starts to cool and turns into the igneous rock. </li></ul><ul><li>&quot;Igneous Rocks.&quot; Oracle ThinkQuest . ThinkQuest Junior, Mar. 2000. Web. 20 Nov. 2011. <http://library.thinkquest.org/J002289/igneous.html>. </li></ul><ul><li>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>. </li></ul>
  • 4. <ul><li>I picked this rock up a little past Tranquillity, (near my home town San Joaquin) by a little stream. It seems to me that this rock is a Diorite. </li></ul><ul><li>Diorite is an intrusive Igneous Rock. Its coarse-grained to the touch and it contains a mixture of feldspar, pyroxene, hornblende, and sometimes quartz. </li></ul>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>.
  • 5. So Long <ul><li>“ Interstate 5 (I-5) is the primary north-south freeway in the state of California. It runs from the Mexican border to the Oregon border and passes through the major metropolitan areas of San Diego, Los Angeles and Sacramento”. </li></ul><ul><li>Along the way a city that we passed was Santa Clarita Valley. This city is geologically diverse, Fossils, howlite, and oil have been found here. During the 1800’s there was even a gold rush. </li></ul><ul><li>“ Most of the valley is composed of sedimentary rocks ranging from 30 million years old to about 1.8 million years old” . </li></ul><ul><li>Foster, B. D. &quot;Landslides in the Interstate 5.&quot; Special Report 188 . Department of Conservation, 2003. Web. 17 Oct. 2011. <http://www.consrv.ca.gov/cgs/rghm/landslides/SR_188/Documents/CT005laREPORT.pdf>. </li></ul><ul><li>Ballard, Michael. &quot;Brief Explanation of the Geology of the Santa Clarita Valley.&quot; Welcome To the Los Angeles Rocks N' Roads Page . 2009. Web. 01 Dec. 2011. <http://www.scvresources.com/geology/scv_geology.htm>. </li></ul>
  • 6. Sedimentary Rocks <ul><li>Sedimentary rocks are formed by rocks that have been broken up into smaller pieces by weathering. Theses pieces flow along different places such as rivers or streams and once they settle into a new place they begin to pile up and form flat layers. After a long time these pieces become pressed together until solid. Your result is a Sedimentary rock. </li></ul><ul><li>&quot;Sedimentary Rocks.&quot; Oracle ThinkQuest . ThinkQuest Junior, Mar. 2000. Web. 20 Nov. 2011. <http://library.thinkquest.org/J002289/sed.html>. </li></ul><ul><li>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>. </li></ul>
  • 7. <ul><li>I found this rock on my way to Los Angeles on I-5. I believe it’s a Conglomerate . </li></ul><ul><li>A conglomerate contains large round pieces. The space between these “pebbles” is filled with smaller particles and/or chemical cement that binds rock together. </li></ul>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>.
  • 8. <ul><li>Also found on I-5, this sample is Shale another form of a sedimentary rock. </li></ul><ul><li>Shale is made up of clay size weathering debris that typically breaks into thin flat pieces. </li></ul>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>.
  • 9. Metamorphic Rocks <ul><li>“ Metamorphic rocks form deep in the earth where high temperature, a great amount of pressure and chemical reactions cause one type of rock to change into another type of rock”. </li></ul><ul><li>&quot; Metamorphic Rocks.&quot; Oracle ThinkQuest . ThinkQuest Junior, Mar. 2000. Web. 20 Nov. 2011. <http://library.thinkquest.org/J002289/meta.html>. </li></ul><ul><li>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>. </li></ul>
  • 10. I believe this sample is a Hornfels, picked up on I-5 as well. <ul><li>Hornfels are fine-grained nonfoliated rocks with no specific composition. It is produced by contact metamorphism. </li></ul>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science . Geology.com, 2011. Web. 17 Oct. 2011. <http://geology.com/rocks/>.
  • 11. <ul><li>This is my last sample, this was picked up in Tranquillity as well by some railroad tracks. This sample seems to be basalt . </li></ul><ul><li>Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals . </li></ul>&quot;Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.&quot; Geology.com: News and Information for Geology & Earth Science .
