3.1.1 Regional Geology
The Chittoor District forms with part of Indian Peninsular Gneiss, which has remained stable since formation of the crust. They are exposed in the most of the district. The region of the subject area is belonging to Peninsular Gneiss of Archean group. The Peninsular Gnessic Complex comprising migmatite gneiss, grey granodiorite, porphyritic granite and intruded by dolerite and aplite veins.
7
The Peninsular Gneissic Complex comprises of gneiss – migmatite – granite suite of rocks. They are highly variable in mineralogical composition appearance structure and relative ages. The individual members have not been distinguished in a major part of the area. However, granite and migmatite gneiss occupy a large part of the area while bands of relatively younger coarse – grained gneissic granite occur in the north eastern part. The Chittoor belt located along the Peninsular Gneissic Complex comprises a complex assemblage of gneissic variants and granitic rocks which occupy almost the entire lease area the Peninsular Gneissic Complex in the area is representing mostly by Biotite hornblende gneiss granite and migmatite in north eastern part of the lease area and made up of rocks of high grade metamorphism, migmatisation and intense deformation. These granites, which are often porphyritic, are intrusive into the gneissic terrain and contain alkali feldspar space. The later in parts the colour to the granite which ranges from light to deep pink because of the massive nature of these intrusive they are amenable for producing sizeable road metal (aggregates), due to the wide spaced joint pattern in hearted to them. The granite deposits are mostly confined to the belt between Kadapa and Chittoor.
Geology of the Area
Entire quarry lease area is covered with Road Metal & Building Stone which is rising up to 10 M above ground level trending SW – NE, the strike length of the body measured 212 M in the area with an average width of 124 M.
4.0 QUARRYING CARRIED OUT

5.0 RESERVES
Geological traverses in the quarry and the study exposures in the vicinity of quarries facilitated to access the shape and size of the deposit in the area. It is a hill deposit rising 10 M above ground level within the quarry lease area (The lowest contour is 35 M and highest contour is 45 M). The surface of sheet rock is wavy and irregular.
8
5.1 Method of Estimation of Reserves The deposit is found to be irregular in shape. Hence cross sectional method adopted for Estimation of Geological Reserves. 3 Sections A-A1 to C-C1 were drawn at equal distance perpendicular to the strike direction of the formation to estimate the reserves. The cross sections were drawn perpendicular to the strike direction, the cross sectional area of the individual sections are calculated to arrive at sectional area, the area thus arrived is multiplied by the sectional influence of 30 M (Average) to arrive the volume of road metal and building stone.

The haulage, machinery and the drilling of drill holes generate noise. However, the probable noise level will be within the permissible limits with in 100 d B (A) and will not cause harm.
The machinery will be maintained properly to reduce the noise
The protective noise reducing gear like earmuffs, the company will provide earplugs.
Proper maintenance of equipment 11) Vibration Levels
It is proposed to use low explosives and less quantity to minimise the effects so that the vibration generated will be feeble within 8 Hz.
12) Socio Economic Environment
The main occupation of villagers is agriculture and sheep raring. The commencement of quarrying activity in this area improved the socio-economic status of the local people by creation of employment and paying taxes to gram panchayath.
13) Occupation Health and Safety
The quarrying in this area does not involve any hazardous methods. The quarrying is simple and open cast mining method. In this, the possibilities of small injuries is anticipated. The lessee is providing First Aid facilities at quarry site.
8.3 Management Plan 1. Soil Conservation Methods
The fertile soil available will be used for plantation around site services on dumps and all along the road. Soil mixed with boulders is unfertile which will be used for laying roads.
2. Proposed for reclamation of land affected by quarrying activity during and at
the end of mining
19
The pits that will be developed will be converted into water harvesting structure. Hence, no reclamation proposals are made.
3. In case of forest programme for phased compensatory afforestation
The quarry lease area will not come under forest zone.
4. Measures for Dust Suppression
The quarry operations will involve dust rising methods. The dust anticipated during dry seasons, due to haulage will be suppressed by sprinkling water. For this purpose, tractor mounted sprinkler will be deployed. The dust generated during the drilling will be suppressed by covering the drill rods by gunny cloth and dust extractors will also deployed.
5. Measures to minimum use vibrations due to blasting and check noise
pollution The blasting will be taken up in short depths ranging between 1.5 – 3.0 m in staggered pattern of 2 x 3 M spacing and burden using delayed detonators. The noise generated by compressors, drilling & machinery like proclain / excavators and tippers will be high. The workers in the quarry area will be provided suitable headgear and noise reducing protective gear (Like Cotton Mufflers etc.). The machinery will be maintained properly for minimizing the noise.
6. Treatment and disposal of water from the quarry at beneficiation plant
Road Metal & Building Stone mines does not require beneficiation.
7. Measures for minimising adverse effect on water regime
The quarrying is confined to elevated place. Therefore no adverse effect is anticipated to water regime.
8. Plantation Programme
The quarry lease area is not suitable for plantation as entire area is rocky. The proposals are being made to grow the plantation along the boundary (Refer : Reclamation Plan).
9. Preparation of dumping ground for stacking toxic mineral substance
No toxic minerals are present.
