Abstract Porphyry copper deposits are important for economic value and resources. Some of the common metals found in porphyry copper deposits are gold, silver, and molybdenite. Most porphyry copper deposits can be found along the Pacific Rim and formed during the Tertiary and Quaternary periods. Porphyry copper deposits form through a series of subducting tectonic events, having a copper bearing source, and convection of hydrothermal fluids acting on an igneous intrusion. Introduction…

Neptune the ninth planet for a few years. Of course, that was when Pluto was still considered a planet. Due to Neptune being so far away it is extremely cold. The planet gets 900 times less sunlight than we do here on Earth. It is so cold that the mantle consists of frozen water, methane, and ammonia. Even the core is made up of ice and rock! You could only be in the upper atmosphere and it still be a whopping -360 degrees Fahrenheit. A very noticeable feature of the gas giant was a large storm…

Anatomy and Structure Most training centres will have a chart on the wall with an illustration of a dog’s anatomy as well as skeletal structure. You’ll need to memorise the terms because your instructor will refer to these constantly. But you’ll also gain an appreciation for differences in structure between dogs and how this makes for variation, for example, in the drop of the coat. Planning your grooming How you plan your grooming is critical to workplace safety and your productivity.…

temperate rainforests of the Olympic Peninsula on the west coast of North America. Their habitat lies on the Eastern side of the Olympic mountain range, adjacent to Hood Canal. These solitary cephalopods reach an average size (measured from arm-tip to mantle-tip,) of 30-33 cm. Unlike most other cephalopods, tree octopuses are amphibious, spending only their early life and the period of their mating season in their ancestral aquatic environment. Because of the moistness of the rainforests and…

New crust is generated as plates pull away from each other and can either cause sea floor spreading or new land to be created. An example of a continental rift valley is the Eastern African Rift Valley which is being formed as the Eastern African plate is moving away from the main Africa plate in a north-easterly direction. Plates move apart due to convection currents in the lithosphere. As the crusts move away from each other the crust thins, tension in the lithosphere causes the plate to…

GEOTHERMAL ENERGY 1.1 INTRODUCTION AND DEFINITION Geothermal energy is the utilization of heat present in the deep earth for the purpose of power generation or other direct use application. In general terms, geothermal energy consists of the thermal energy present in the Earth’s crust. Thermal energy in the earth is distributed between the constituent host rock and the natural fluid that is contained in its fractures and pores at temperatures above ambient levels. Globally, the most commonly…
