Geological characters that have a direct bearing on a tunnel project will differ almost in all details in these categories. Only a brief account is given below: Consolidated Rocks: This group includes the massive igneous, sedimentary and […]

Here is a list of top twelve stratigraphical systems developed in India. 1. The Archean Groups: Broadly speaking, all those rocks that are the oldest, have absolutely no evidence of existence of life (in terms of fossils) and undoubtedly form the basic, foundation rocks for all the subsequent formations in Indian stratigraphy are grouped together […]
