Litholog Cuddapah Basin- Generalised Litholog of Cuddapah Basin.pdf
The document provides a detailed overview of the stratigraphy of the Cuddapah Supergroup, including various formations such as srisailam quartzite, cumbum formation, and the papaghni group, with their respective components. It also mentions significant igneous events and age constraints, particularly highlighting components like dolerite, basalt flows, and lamproites. The information is modified from previous studies, emphasizing geological history and formations dating back to over 1900 million years.
