what is geology?

The Graphical representation of purpose specific geological information or data obtained from field (after site investigation) which can be quantified (in numbers), with reference to north at certain scale is known as Engineering Geological Map.It includes lithology (distribution of rock types), soil types (alluval,colluvial,residual etc.), geomorphology (river,stream,slope aspect ,inclination,slope instabilities like mass movements i.e, landslides,debris flow,slope failure etc.). In others words,an engineering geological map is a type of geological map which provides a generalized representation of all those components of a geological environment of significance in landuse planning, and in design, construction and maintenance as applied to civil and mining engineering. Engineering Geological Maps are prepared on a scale of 1:10000 or smaller.
