GEOLOGY AND MINERAL RESOURCES OF KHAMMAM DISTRICT

INTRODUCTION:

Khammam District derived its name from the head quarters town, which is 200 Km east of Hyderabad. The District lies between Lat. 16 Dag. 45 Min. and 18 Deg. 35 min and Long 79 Deg. 47 Min. and 80 Deg. 47 Min. It is bounded on the north by Madhya Pradesh and Orissa States, on the south by Krishna District, on the east by East Godavari and West Godavari District and on the West by Nalgonda and Warangal Districts. The District extends over an area of 16.029 Sq.Km. comprising of 46 Mandals.

PHYSIOGRAPHY:

There are minor isolated hills traversing through north, Central and Southern parts of the District. The eastern end of the District is occupied by a group of hills stretching upto Papikondalu in the South . Some of the prominent hills in the District are located near by Yellandu R.F., Usirikayalapalli, Cheemalapadu R.F., Yerragutta, Wali-Sugreva hills are some of the important hills in the District.

DRAINAGE:

The most important river flowing through the District is the Godavari. The River flows in the West to Eastern direction in the District. The mighty seasonal river is joined by the Sabari, the other river Kinnerasani. The other rivers like Munner, Pealer, Akher and Wyra join Krishna river. River Godavari has the deepest gorge in the Papikonda Hill. This river is navigable from Badrachalam Temple town upto Rajahmundry in East Godavari District.

GEOLOGY OF THE DISTRICT

The District forms a part of the Indian Peninsular shield, which has remained stable since the formation of the crust. They are exposed in the Western and Eastern part of the District. During the Archean Era, parts of the District was occupied by two vast geo-synclines which got deposition of sediments in them. Later, they were subjected to diastrophic movements resulting in folding, faulting and uplifting and subjected to metamorphism. These gave rise to Khondalite and dharwarian suit of rocks. These suit of rocks have occupied in the extreme Eastern, South and central parts of the District. The South and Eastern parts of the District are covered by narrow bands of charnokites. During the late Archaean Era, igneous intrusions of alkaline rocks in Ashwaraopet-Kunavaram belt, basic to ultrabasic rocks and a number of swarm of basic dykes around Khammam, Pegmaties and quartz veins are formed in many parts of the District. At the end of the Archaean Era, there was an invasion of sea covering parts of Khammam, Warangal, Karimnagar, Adilabad and Maharashtra and where argillaceous, calcareous and arenaceious sediments were deposited which were later subjected to folding, faulting and partly metamorphosed during subsequent periods. In the District, These deposits have been refered Pakhals, Albakas and Sultavais and they have occupied the northern and North-Western parts of the District.

After the Proterozoic sedimentation, there was a lull the depositional history of the District for about 300 m.y.i.e., from Cambrian to Permian. By this time a supercontinent Pangea comprising of 5 continents including India was in existence and referred geologically as Gondwana land. The Gondawana period began with the deposition of glacial beds followed by feldspathic sandstones, clays and ferrugeneuous sand stones. There was a luxuriant vegetation during this period which got drifted and deposited by river waters in lakes and inland seas. On burial, these were transformed into coal in course of time. During the late Mesoziac era, there was break up of Gondwana land as a result of which the Pranhit-Godavari basin was uplifted which gave rise to river alluvium on the banks of the Godavari and soil cappings.

ARCHAEANS:

The Archaean rocks comprises of peninsular gneissic complex, Khondalite suit of rocks, charnokites, anorthosites, hornblende/biotite chlorite quartz schists, acidic, alkaline, basic intrusives and veins of quartz and pegmatites.

The Peninsular gneisses consists of hornblende gneisses and biotite gneisses having the foliation tending NNW-SEE with steep dips towards east. They are medium grained, grey in colour and intruded by basic ultra basic and alkaline syenites rocks such as dolerites pyroxehites, gabbros, anorthosites and pegmatites and quartz veins.

The Khondalite suit of rocks represent the earliest sedimentary rocks deposited in a major geosyncline of early Archaean era. They were metamorphosed under (the granulitic facies) high temperature and pressure conditions. They are represented by garnet-sillimanite-graphite gneisses, felspathic gneisses, graphits schists, calc – granulites and quartzites in the district. These rocks are found in Chandrugonda , Julurpad, Kukunur, Chintur, V.R.Puram, Velair & Ashwaraopet Mandals.

The Charnockites and Pyroxene granulites occur mostly as bands in the Khondalite suit of rocks and are characterizes by the presence of minerals such as diopside, hypersthene etc., The Charnockites range in composition from acidic to basic and ultrabasic. These rocks occur in Chandrugonda, Julurpad, Enkur, Chintur, V.R.Puram, velain, Ashwaraopet and Madhira Mandals.

The Dharwars comprises of banded magnetite quartzite, ferruginous quartzites, quartz – chlorite schists, mica schists, amphibolites and calc-schists. These rocks are exposed partly in Yerrupalem, Madhira, Kallur, Talada, Mangur, Aswapuram, Burgampahad, Konjerla, Tekulapalli & Paloncha.

The alkaline rocks like nepheline-corundum syentite and zircon-syenite are intrusives into the Khondalites in a 32 Km long narrow beld in Kunavaram-Vinayakapuram area.

Pegmatites, quartz veins, and swarms of dolerites have cut through Archaean suit of rocks.

PAKHAL SUPER GROUP:

The Pakhal Super group comprises of Mallampalli, Mulug and Albaka Group in the order of super position. These rocks rest non-conformably over the Archaean basement. They consists of variable proportions of calcareous argillaceous, and arenaceous sediments. The lower part of the Super Group is Mallampalli Group is dominated by dolomite. The middle part by Mulug Group, consists of Somandewara quartzite and Tippapuram shale. The Albaka Group is restricted to the Eastern part of the District and is represented by homogenous sequence of sandstone and limestone. The Pakhal have a regional strike of NW-SE to the N-S direction, and are exposed in Bonakal, chintakani, Khammam (U), Kamepali, Garla, Bayyaram, Gundala, Singareni, Yellandu, Tekulapalli and Palvoncha Mandals.

GONDWANA SUPER GROUP:

The Gondwana rocks in the District forms a part of Pranhita Godavari basin of fossiliferous fluviatile sediments of Dermain to Jusassic age. The Gondwana Super Group sediments occurring in the District are divisible into the lower Gondwana Group and the upper Gondwana Group. The lower Gondwana Group comprises of Talchirs, Barkars Barren measure and Kamthi formations where as the upper Gondwana Group is represented by Kota formation. The Talchirs consist of glacioal boulder beds, sandstones and shales. The boulder bed is of glacial origin and consists of boulders, cobbles and pebbles of Archaeans and Pakhals embedded in argillaceous matrix. The sandstones are brown in colour, medium to coarse grained and felspathic. The shales are pale green in colour and are moderately compact. These outcrops are exposed near Cherla-Ammagaripalli, south of Morampalle near Bhurgampahad, Gouridevipeta, NW of Yellandu, NW of Kallur NE of Manbotgudem (17 deg. 51 Min. 45 Sec. : 80 Deg. 43 Min. 20 Sec), NE of Chinthakunta (17 Deg. 46 Min. 40 sec : 80 deg. 34 Min. 20 Sec.)

Khammam District is one of the important district in the context of occurrences of black granite.  A number dyke swarms (black granite) traverse the Archean Peninsular gneissic complex around Khammam town, they run at places for over a length of 3 or 4 kilometers with a width of 100 to 150 metres

The major deposits of black granite in the district are found within a radius of about 20 KM around Khammam town.  The dykes are dolerites with coloured ranging from medium grey to jet black.  The rocks are medium to coarse grained.  Good quality black granites, some with greenish black colour are seen in and around Edulapuram, Polapalli and Arempula villages and are extensively quarried.  So also are the prospects near Khanapur and Pandreguppalli Villages in Mudigonda Mandal.  Black granites of Nelakondapalli exhibit greenish tinges due to predominance of augitic in the rock.

However, many occurrences in Khammam district are highly jointed and thus cannot yield big blocks; also some of them have benefits such as the blotches and flowers of plagioclase feldspar traversed by and thin veins of epidote, thus rendering the rock commercially less attractive.
