Branches Of Geology

1. Mineralogy-

Mineralogy defined as the offshoot of geology dealing with the scientific analysis of the minerals, including chemistry, structure, physical and optical properties and its artifacts.

2. Structural Geology-

The branch of geology dealing with the three-dimensional distribution of the rock and its deformational history.

3. Oceanography-

The discipline of geology dealing with the studies of oceans and seas including their framework, physical and chemical properties, origin and its ancient history and current direction.

4. Petrology-

Petrology is systematic studies of rocks, their origin, structure, composition and much focus on igneous, metamorphic and sedimentary rocks.

5. Geomorphology-

It deals with the physical features of the surface i.e its land forms, process and sediments and their relation with geological structures.

6. Paleontology-

"Paleo" means "Past" and "ontology" means "Life History" , so it is the study of pre-historic life of the earth. The record of pre-historic life forms are found within rocks as fossils.

7. Stratigraphy-

Stratigraphy deals with the sequential arrangement of layered rocks according to the time of their formation on the surface of the Earth.

8. Economic Geology-

It deals with the study of minerals, ore and fossil fuels of economic importance.

9. Hydrology-

It is the science that encompasses the occurence, distribution, movement and properties of waters of the Earth and their relationships within each phase of hydrological cycle.

10. Historical Geology-

Historical Geology is a science which deals with historical development of the earth. It aims at reconstruction of the earth's evolutionary history and formulation of general laws governing the evolution.

HOW TO MAKE A GEOLOGICAL REPORT?

What is a GEOLOGICAL REPORT? Geological reports are concise, informative and well documented reports used to present, analyse and summarise field data for both industry and research purposes. They should be accompanied by geological maps, figures, stratigraphic columns, tables, graphs etc. PREPARATION First plan the layout, section by section; then draft each section using all your notes, maps, laboratory results and references gathered from other sources. Then list the illustrations needed to support the text. Finally, lay sections out in your choosen order, before gathering them together to edit them. Does not spare the paper, allow plenty of room between the lines and at the margins for corrections, alterations and additions. REVISION AND EDITING First, a rough draft gets the essential facts and information in order. The next stage is to revise it and re-edit. The order of some paragraphs may need changing, spelling mistakes corrected, grammar improved. Indicate where illustratio

The 10 Most Toxic Minerals

1. Cinnabar- Cinnabar is the main ore of mercury, the most toxic mineral on Earth. The name itself means dragons bloods. Form near volcanoes and sulphur deposits, the bright red colour signals danger. Copyright: Courtesy of Ted Boente; John H. Gerard/Encyclopedia Brittanica, Inc. 2. Orpiment- Originate from Latin auri , " golden "; pigmentum , " paint ". Composed of Arsenic Sulfide, the lethal and chemically reactive orpiment crystals are found growing below the surface in mineral formations, often near hydrothermal veins. It may crumble into dangerous powder when exposed to light. Holding crystals in your hands may release carcinogenic , neurotoxic powder. Copyright: U.S. Geological Survey 3. Stibnite- Antimony Sulphide, the principle ore of antimony. It is used in manufacturing of matches and fireworks. Mines near Oksaku, Japan produce the best stibnite crystals in the world.

Silicates

Introduction: Silicates are a fascinating and diverse group of minerals that form the foundation of the Earth's crust. They are composed of silicon and oxygen, the two most abundant elements in the Earth's crust. Silicates exhibit a wide range of chemical compositions and crystal structures, making them crucial components of rocks, soils, and various industrial applications. The fundamental unit in the building of silicate minerals is the SiO 4 -4 tetrahedron in which the silicon atom is situated at the centre of tetrahedron where corners are occupied by four oxygen atoms. The radius ratio of Si +4 to O -2 requires that Si +4 be coordinated by 4 O -2 ions in tetrahedral coordination. In order to neutralize the +4 charge on the Si cation, one negative charge from each of the Oxygen will reach the Si cation. Thus each Oxygen will be left with a net charge of -1, resulting in a SiO 4 -4 tetrahedral group that can be bond to other cations. It is this SiO 4 - tetrahedron th
