Due to the discovery of shock metamorphism rocks (suevite breccia) and melted original rocks scattering in the southern area of Bukit Bunuh‚ it was suspected that the area had the possibility of being impacted by meteorite. The founded boulders made the archaeologists from the Centre for Global Archaeological Research (CGAR) of Universiti Sains Malaysia (USM) to propose of the possibility of Bukit Bunuh as a meteorite impact site. This proposal was led to intense research in the area by utilizing

Photographer’s Choice RF/ Getty Images The Earth’s crust is an extremely thin layer of rock‚ like the skin of an apple in relative terms. It amounts to less than half of 1 percent of the planet. But the crust is exceptionally important‚ and not just because we live on it. The crust can be thicker than 80 kilometers in some spots‚ less than one kilometer in others. Underneath it is the mantle‚ a layer of rock some 2700 kilometers thick that accounts for the bulk of the Earth. The crust is primarily

starts 1.7 billion years ago with the Idaho Springs gneiss found at the upper parking lot of Red Rocks Amphitheater. This rock is made up of potassium feldspar and quartz predominantly‚ which makes the rock appear mostly white in color‚ however‚ hematite stains the outside to give it a red color. The Idaho Springs gneiss was created by two geological events‚ both the growing of the North American basement rock and the formation of super continent Columbia. This can be seen because the Idaho Springs gneiss

clumps held together by static charge. -These mineral grains grew into small pieces of rock orbiting the sun -over the next few million years some of these rocks collided and grew bigger -when a rock grew to become around half a mile across‚ its gravitational pull became strong enough to pull objects towards it. (The bigger the rock was the faster it grew because it had higher gravitational pull) -so that biggest rock eventually grew to become ‘the fledgling earth’ -soon this small planet grew to attract

The Great Smoky Mountains The Great Smoky Mountains landform is mostly sedimentary rocks that were formed by the accumulation of sand‚ clay‚ silt‚ sand‚ gravel‚ and minor amounts of calcium carbonate in flat-lying layers. According to The Great Smoky Mountain’s website‚ about 545 million years ago the sediments were formed and large amounts of those sediments were washed down into lowland basins from adjacent highlands. The colliding between the edge of the North American tectonic plate and the

They found another tunnel‚ but it had rocks in front of it so they blew it up. The rocks fell in the sea and it caused the sea to make a wave which pushed them in the tunnel. Suddenly‚ they were falling down until water shot up and caused the raft to head into a different passage. The passage ended up being a volcano

The asymmetric and symmetric stretching bands of CH2 are observed in the range from 2900 to 2700 cm-1 and this stretching band is mainly coupled with the CH3 stretching vibration. Mirtazapine has only one CH3 group. The C-H stretching vibrations of methyl are observed between 3000 and 2900 cm-1. A methyl group

They produce a topographical- geological map of the oasis and discuss the stratigraphy of the rock exposed. They distinguished three topographic features; the bounding escarpments; the conical hills within the depression and the oasis floor. They notice that the southern scarp is steeper than the northern scarp. The eastern scarp has smooth outline
