Geological Report on Limestone Exploration Of Bhatvadiya B Block Of Kalyanpur Taluka, Devbhumi Dwarka District, Gujarat EXECUTIVE SUMMARY Prepared for: Gujarat Mineral Research & Development Society Government of Gujarat Prepared By: Vinayak Engimech Pvt. Ltd. Bellevue Compound, Opp. Gandhigram Station, Near SBI, Ahmedabad 380009 Gujarat.
Executive Summary Bhatvadiya B Block is a part of Kalyanpur Limestone Drilling Scheme in Kalyanpur Taluka of Devbhumi Dwarka District, Gujarat. It is irregular polygonal block with an area of 169.959 hectare having approximate dimension of 2.2 km in length and 2.2 km in width. This block named as Bhatvadiya B Block was explored by Gujarat Mineral Research and Development Society (GMRDS), Industries and Mines Department, Gandhinagar through outsourcing. Drilling agency Vinayak Engimech Pvt. Ltd has carried out drilling in this Bhatvadiya B block during 2013-2015. The area cover mainly cement grade limestone and marl deposits of tertiary period. The mineralized zone belongs to Gaj formation and Dwarka Formation ranging in age from Lower Miocene to Pliocene. At few places, limestone encounter directly at surface and sometimes overburden of soil of 0.5 m to 1 m is there. Bhatvadiya B block has a relief of 21 m. Highest and lowest elevation points in this block area are 28 m and 7 m respectively as per data given by Soham Ferro Menganease Pvt. Ltd. Overall topography of area is flat with slight undulation and gently rolling. The block area falls under survey of India toposheet no. 41 F/4 of Kalyanpur Taluka of Devbhumi Dwarka District. Dwarka is very important pilgrimage appx 40 km away from block area. And area is accessible throughout the year. Soham Ferro Menganease Pvt. Ltd. has organized the Topographic survey using Total Station Theodolites and DGPS survey to determine the boundary of the block. And classified the block area as government and private land. In Bhatvadiya
B block out of 169.959 hectare block area, around 115.388 hectare area is government land and 54.571hectare area is private/ agricultural land. 58 diamond core drillholes, totaling 4543.80 meterage have been drilled within Bhatvadiya B block in 200 m grid. Around 644 no of half splitted core samples have been sent to Petrography and Mineral Chemistry Laboratory, Gandhinagar for assay. Element suit determined at Petrography and Mineral Chemistry Laboratory, Gandhinagar include SiO 2, Al 2 O 3, Fe 2 O 3, CaO, MgO, Na 2 O, K 2 O, P 2 O 5, TiO 2, MnO, SO 3 and loss along with specific gravity data. Vinayak Engimech Pvt. Ltd. has prepared geological report by considering drilling data and analysis provided by Petrography and Mineral Chemistry Laboratory, Gandhinagar. For resource estimation analysis data, grade of limestone, area of influence method used. The main mineralized body of limestone belonging to Gaj and Dwarka formation. In Bhatvadiya B block exploration carried out is of G-1 stage (i.e. detailed exploration) & G-2 stage (i.e. general exploration). The geological resources of limestone in the block has been classified based on Mineral (Evidence of Mineral Contents) Rules, 2015 notified by Ministry of Mines. Total geological resource in Bhatvadiya B block is 52.51 Mt. of indicated mineral resource (332 category). The following table summarizes the grade wise indicated geological resource (332) of Bhatvadiya B Block.
