Sedimentology is defined as the study of Sediments and the process of their formation that took place in the prehistoric times. More than 75% of the earth surface is covered by Sediments and Sedimentary rocks. These studies are of great importance for investigating the availability of resources such as coal, gas,oil, groundwater and geothermal energy. Furthermore they avail raw materials for monument stone, chemical industry and bulk materials for building purposes.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
