Engineering Geology Lab

It helps in understanding the natural crystalline structure of rocks and minerals and gives an idea of the faults and folds which occur. And also find the detailed structure with the help of microscope. This lab familiarizes the students will introduce some basic geologic principles, starting off with basic identification of geologic materials, map use and deformation of rock analogs. Then they will head outdoors to explore geologic and geophysical mapping techniques; and illustrate environmental, geologic and engineering topics through visits to local field sites. Also learn to describe rocks and rock masses in a quantitative manner to be supplemented by normal geological descriptions. Empowering them to understand the state of stress of an element of rock to devise a testing program for the characterization of rock materials and rock masses. Using methodologies they will be capable of carrying out suitable stability analyses for surface and underground structures such as tunneling, mining operations and large dams.
