Stonehenge Vs. Pantheon

Stonehenge: * New geological research is currently being carried out to identify the sites of origin more accurately. How the stones were transported for over 250km (156 miles) to Stonehenge remains unknown, but it is probable that a combination of transport via water networks and hauling over land brought them to the site. The larger sarsen stones are a type of sandstone, a stone found scattered across southern England. Most archaeologists believe that these stones were brought from the Marlborough…

Environmental Geology

In 2006, seismic researchers can predict the location and direction of earthquakes by merely 10 to 20 minutes before it happens. Researchers use ultrasounds to assess earthquakes faster. Precise ultrasound images were recorded from the fault which is ruptured and the direction the rupture goes (American Institute of Physics [AIP], 2006). In 2008, seismic researchers can now predict earthquakes with much more preciseness and earlier than other previous equipments. A researcher from Rice University named Fenglin Nui and some of…

Rock Cycle for Kids

As all the students flooded into the classroom and started to unpack, the teacher, Mrs.Bentley, said, “Today you are going on a mini field trip to a park with Mrs.Crystal, who studies rocks and minerals! What you’re about to learn is a surprise!” The students cheered, wondering why they were going there. They gladly followed Mrs.Crystal out of the room and to the park nearby. Mrs. Crystal asked, “Do you know what inside a volcano?” Many hands shot up. She…

Lab Report_ Point Load Test

Aim: To determine the strength characteristics of a rock using the point load test and visual judgement. Materials Loading device Loading frame Pump Ram Platens Rock Caliper Method (Standard, 2007) 1. Measure the dimensions of the rock which includes the diameter and length 2. Find the length to diameter ratio to determine which test will be used. If the ratio is greater than 1 use diametrical test. But if the ratio is between 0.6 and 1 use axial test 3….

_how the Earth Was Formed_ Video Notes

Theory: -sun was surrounded by a cloud of dust and gas -as cloud cooled little grains of minerals started forming -grains of minerals started bumping into each other (Problem was nobody could explain how these microscopic minerals formed a planet) Then in 2003 astronaut Don Pettit performed an experiment onboard the international space station. He put some salt in a plastic bag and found that almost immediately the grains started gathering together into little clumps held together by static charge….

Principle of Earth Science

The three stages according from the oldest to the youngest formation are granite, basalt and lastly andesite formation. This will discuss about the formation, composition, type of intrusion and cooling history of each stages. The granite formation is the oldest stage since granite is formed usually beneath the crust about 1. 5 km up to 50 km depth. Primarily, granite is composed of silicon and alumina about 72. 04% and 14. 42%, respectively. The formation of granite occurs through extreme…

Geology and Technology

The field of geology helps us understand our surroundings on earth. The benefits of geology include how to protect our environment and supplies us with natural resources. Geology helps assist us in avoiding geologic hazards and is based on the scientific method. One of the great contributions to human understanding made by geology is the concept of the vastness of geologic time. None of these benefits could have ever been discovered or even thought of if science did not collide…

Ophiolite Complexes

Ophiolite complexes are the suite of rocks that became the product of the spreading centers of plate boundaries. Ophiolites or “snake stones” are originally coined by Alexandre Brongniart in 1813 mainly because of its green rocks comprising of serpentine and diabase. Initially, geologists and paleontologists of the 1950s and 1960s hypothesized that oceanic crust emplacements and seafloor spreading might be the cause of ophiolite complexes. According to Kearey and Vine (1996, 24), earlier propositions on ophiolite complexes are associated with…

Landslide and Debris Flow

A. A landslide is when a mass of soil, rocks and other debris moves down a slope, powered by the force of gravity. Sometimes, this movement is so sudden and rapid that it causes devastating loss of life and structural damage. (http://www.health24.com/medical/Condition_centres/777-792-1461-2097,34702.asp) B. A landslide or landslip is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments….

Fossils Nurse

A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground, the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from…

Field Trip Report

Excursion at the Montauban mine (September 21st, 2014) Montauban is a Zn-rich VMS deposit that has been exploited from 1910 to the 1960s including several gold-rich zones. The deposit is hosted in highly deformed volcanic rocks metamorphosed to the upper amphibolite grade. Part of the deposit is observable on outcrops and a section from the altered footwall to unaltered basalts in the hanging wall has been visited by a group of six student from the Université Laval and the INRS-ETE….

The Shocking Truth About Impact Metamorphism

Sometimes I happen to stop for a while, think and then wonder about the truth that lies beyond the things I see around me. Some questions even come to my mind.   Why does this volcano look like that?  Or how come there is a lake in that area?  What makes the tropical regions more diverse than temperate regions?  And many more questions.   Many of them are really hard to answer without further research. But through studying and researching about certain…

The Philippines’ Landslide

Mass wasting is defined as the down slope movement of rock and regolith near the Earth’s surface mainly due to the force of gravity. Rock slides and debris slides result when rocks or debris slide down a pre-existing surface, such as a bedding plane, foliation surface, or joint surface. On February 17, 2006 the Philippines was hit by landslides. In Southern Leyte mudslides destroyed the mountain village (Barangay) Guinsaugon. During schooltime between 9 a.m. and 10 a.m., an elementary school…

Geological Forces That Shape the Earth

Diastrophism Defined: •Comes from the Greek word meaning a “twisting” deformation of the Earth’s crust. All processes that move, or elevate or build up portions of the Earth’s crust comes under this. •Diastrophism covers movement of solid (plastic) material, as opposed to movement of molten material which is covered by volcanism. •The most obvious evidence of diastrophic movement can be seen where sedimentary rocks have been bent, broken or tilted. Types of Earth Movement: a.Uplift •Is the movement of the…
