Highlands underwent high-grade metamorphism‚ and at a series of locations different intrusions occurred during the Grenville Orogeny. Certain evidences to help back up this claim are the presence of gneissic rock and index minerals such as Siliminite and Garnet. Since the mineral composition indicates granulite facies‚ then its protolithic content is pelitic‚ meaning shale/mudrock. Also‚ a series of magmatic intrusions were shown the form of Lamprophyre‚ Granite‚ Pegmatite‚ and Diorite. Introduction

1. Introduction The term asbestos is used to describe a group of six different fibrous minerals that occur naturally in the environment (Leake‚ et al.‚ 1997). Asbestos minerals consist of thin‚ separable fibers that have a parallel arrangement (Ross & Nolan‚ 2003) and are widespread in the environment as they can occur as large natural deposits or as contaminants in other minerals (Kamp & Weitzman‚ 1999). Asbestos fibers are nonvolatile and insoluble‚ so their natural tendency is to settle out of

Geology a science that examines the earth‚ its form and composition‚ and the changes it has undergone and is undergoing involves the knowledge of what happened before and the events occurring within the atmosphere requires not only a study of the materials found on earth but an understanding of the various geologic processes aims to develop an understanding of the earth’s materials and how these materials were changed and modified through the action of natural forces over a period of time Geology

resources are emerged in Australia. One of the most important industries is mining. Australia has the world’s largest reserves of several mineral commodities in both minerals and energy resources. The Mining sector includes all units mainly engaged in mining‚ including the mineral exploration‚ and the provision of a wide variety of services supporting mining and mineral exploration. The discovery of the gold in New South Wales and Victoria has forced Australia into the group leader in mining countries

Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and they can then be moved within the plant to the cells that need them. Plants obtain water from the soil through their roots. The roots are adapted to absorb large volumes of water by having many tiny root hairs‚ which

Igneous Textures Cooling rates influence igneous rock textures. Rapid cooling at the earth’s surface results in tiny mineral crystals that can only be seen under a microscope. The resulting extrusive igneous rocks have an aphanitic texture. Rocks that form as magma cools slowly underground (intrusive igneous rocks) develop phaneritic textures‚ in which individual mineral crystals can be seen without a microscope. Some igneous rocks exhibit visible crystals (phenocrysts) in a matrix of tiny

HOW DOES ICELAND UTILIZE VOLCANIC ACTIVITY TO ITS ADVANTAGE? Geothermal energy. The first reason why Iceland utilizes its volcanic activity to its advantage is by using geothermal energy. Geothermal energy production works by the radioactive decay f several types of rocks containing radioactive substances (such as uranium) releasing heat energy. In the volcanic areas in Iceland‚ the rocks heat the water so that it then rises to the surface (naturally) as hot water and steam. The steam can then
