District Profile

Topography

The undulating black cotton soil strips, cut by numerous nalas, characterise the region of the Dharwar schists, which is now practically denuded of trees and presents a monotonous landscape, while the gneissic region is generally more or less broken and covered with a thin mantle of red loamy soil. Gneissic hills, Sedimentary formations, which cover a small belt of the region adjoining the confluence of the Krishna and the Tungabhadra rivers, occupy more or less flat plateaus.

Regionally viewed, the hills in the area present some structural features which are of interest in relation to the geology of the area: 1) Taking the most south westerly group, the hills of Karigudda, Manvi and Rabhinakal show a continuity along roughly north-west south-east directions: 2) from Sirwar and Yermasagar, running in a roughly south-east direction, may be recognised the hill of Madhugiri, Neermanvi, Gorkal, Kurvi and the one two miles west of Kamalahatti; 3) between Masarakal and Gabbur, a number of gneissic hills are seen at Kakargal. Jinnapur, Hungundabad. Ramdurga, Jagatkal, Khardigud, Maladkal and Gabbur . The hills around Uttanur are seen to be in line with the south-western group of hillocks in the above areaas also the hill-clusters around Kalmala and Kallur, are seen to be situated in the same north-west and South-east disposition as that of the group of gneissic hills enumerated above; and 4) the hills around Raichur, which constitute a prominent landmark in the area, may also be seen roughly to display north-west and south-east trends.
