A 3D photogrammetric approach in mapping meso-scale folds and shears in structurally controlled syngenetic Mn-mineralised zones of Shivrajpur Region, Eastern Gujarat, India

The term mapping means an illustration of an entity/entities present within a same/different domains to acknowledge its association with each other. This representation in the past few decades has given a broad spectrum in terms of its utility and applicability. The present article offers a simplified text to apply an unorthodox way of mapping the terrain using a 3D photogrammetric approach. This technique has emerged though less than a decade has an ability to solve many geological problems concerned with outcrop accessibility as well as its interpretations. Here, this method has been used in an abandoned mine section to map the folded outcrop enriched with manganese mineralisation from the Shivrajpur Formation, Champaner Group, a part of Upper Aravalli Supergroup. The former segment of the chapter depicts the overall framework of rocks that belong to the area under investigation and analogous structures developed within them, while the latter explicit the use of 3D photogrammetry in meso-scale mapping as well as its interpretations.
