4. WARDIERE INC. 2022 Company Explanation My hometown is in Vizianagaram District, Andhrapradesh . There are many reservoirs and beautiful national highways in our district. First boundary of the district need to created in the Google Earth Pro. All of the paths and areas were digitalized and shown in the above map. Thatipudi , Andra , Vattigedda , Tadipudi , Peddagadda etc are the reservoirs lies in the Vizianagaram district. There are six rivers draining the district, viz. Nagavali , Gosthani , Suvarnamukhi , Champavati , Vegavathi , and Gomukhi . They originate in the Eastern Ghats and after flowing through the district, finally join Bay of Bengal. The National Highways are represented by the black path lines. We can create the forested areas as a polygon. The forest cover in the district based on the interpretation of IRS R2 LISS III data (2015-16) is 1097.81 sq. km which is 16.79 % of the total geographical area (TGA) of the district. Hills are mentioned in brown colour . The district is endowed with mineral deposits of Manganese, Graphite, Mica, Clay, Quartzite, Molybdenite , Sillimanite , Iron ore and Kankar . The main activity in Major Mineral is Manganese and Quartzite mining and the others are Moulding Sand, Lime Kankar , Feldspar, Mica, Graphite, and Semi Precious stones. Minor Minerals occurring in this district are Road Metal, Building Stone, Gravel and Colour Granite. Geologically, the district constitutes a part of Eastern Ghats Mobile Belt of Archaean age. It includes rocks of Khondalite Group, Charnockite Group and Migmatite complex. Sediments of Upper Gondwana , Cainozoic laterite and Quaternary deposits overlie the Archaeans . The lithological units of Khondalite Group include quartzite, talc- granulite and talc-silicate rock with bands and pockets of crystalline limestone +- scapolite +- wollastonite and garnetiferous quartzofeldspathic gneiss with Sillimanite +- graphite. Khondalite is at places sheared and silicified with thin bands of chert . The various units of Charnockite Group include pyroxene granulite (basic Charnockite ) and charnockite (acid/intermediate). The Migmatite complex includes porphyroblastic hypersthene-biotite gneiss, hypersthene-quartz-feldspar augen gneiss, cordierite-hypersthene gneiss +- biotite, and at places, granitoid gneiss. Gneissosity in the granite gneiss is more pronounced in the vicinity of Khondalite . Thick veins of pegmatite traverse these rocks in the north-western part of the area. Upper Gondwana sandstone (containing plant fossils viz Hausmania sp. And Cladophlebis sp. And indeterminate bark impressions occur close to the coast, in the southeast. Extensive capping of aluminous laterite is seen over Khondalite Group. Quarternary formations, including brown, residual soil, and fluvial and marine sediments, occur along the river courses and coast, respectively.
