ABSTRACT Gujarat Government has come up with new mining rules having auction policy which is fair, transparent, non-discriminatory and in line with the Supreme Court and high court orders for the allocation of natural resources. According to New rules of Gujarat Minor Mineral Concession rules 2017 the potential area of quarry lease shall be identified and demarcated using DGPS and shall have a topographic and geological map prepared using total station. Also as per part-A geological study report is required in which evidence of mineral resources shall have been established for the block to be auctioned. So this study is required for the auction purpose of a blacktrap block at village Sonpari. Exploration of the said project was done on October 2017 for the estimation of the reserves. After carrying out G2 stage (General Exploration) exploration a total 23, 62, 880 metric tons reserves of blacktrap has been estimated assuming total 20 mtr thickness of the deposit. The deposit of blacktrap is huge and as it is nearer to the proximity of city like Bhavnagar and Rajkot where transportation cost is less and demand is more so it is good block for auction. 3 | Page Vill: - Sonpari , Tal. – Palitana , Dist.: Bhavnagar . BLACK TRAP BLOCK – D AREA: - 04.16.00 hect. CHAPTER I INTRODUCTION Bhavnagar district is one of the most developed districts of Saurashtra region of Gujarat State. Its district headquarter is located in Bhavnagar city. Bhavnagar was founded by Bhavsinhji Gohil (1703-64 AD) in 1723 AD near the Gulf of Khambhat, on a carefully chosen strategic location having potential of maritime trade. Bhavnagar district has the area of 9980.9 Sq km and is located in southern part of the Saurashtra Region of Gujarat State. It lies between north latitude 210 18’ and 22018’ and east longitudes 710 15’ and 720 18’. It falls in the Survey of India (SOI) degree sheets 41 O and 46 C. District Bhavnagar is bounded by Surendranagar and Ahmedabad districts of Gujarat in the north, Rajkot and Amreli districts of Gujarat in the west, Arabian Sea and part of Amreli district in the south and the Gulf of Cambay (Gulf of Kambhat) in the east. Bhavnagar District is divided into ten talukas: Bhavnagar, Sihor, Umarala, Gariyadhar, Palitana, Mahuva, Talaja, Ghogha, Jesar and Vallbhipur. [4] There are close to 800 villages in this district. The Minerals found in the district are Gravel, Ordinary sand, clay, Blacktrap, Lignite, Laterite, ,which are commonly used in the construction of residential buildings and industrial houses and business complexes or huge Shopping Centers and other infrastructure projects. Blacktrap has long been used as aggregate for construction of roads and building. Today, the demand for these materials continues to rise. Gujarat Government has come up with new mining rules having auction policy which is fair, transparent, non- discriminatory and in line with the Supreme Court and high court orders for the allocation of natural resources. According to New rules of Gujarat Minor Mineral Concession rules 2017 the potential area of quarry lease shall be identified and demarcated using DGPS and shall have a topographic and geological map prepared using total station. Also as per part-A geological study report is required in which evidence of mineral resources shall have been established for the block to be auctioned. So this study is required for the auction purpose of a blacktrap block at village Sonpari. 4 | Page Vill: - Sonpari , Tal. – Palitana , Dist.: Bhavnagar . BLACK TRAP BLOCK – D AREA: - 04.16.00 hect.

BLACK TRAP BLOCK – D AREA: - 04.16.00 hect. PREVIOUS WORK a) Exploration if done Exploration of the area was not done previously. Bhavnagar district is majorly covered with Blacktrap deposits. Department had carried out regional geological mapping for the area. Regional geological map prepared by CGM is attached as Plate no. III. b) Mining if carried out The area under exploration is a virgin area. Previously no mining were carried out in this area. PRESENT WORK a) Objective of present work Present work includes topographical survey, DGPS survey and geological exploration in proposed block area to assess the blacktrap resource potentiality in the block for auction purpose. The exploration work was carried out in October, 2017. Topographic survey was carried out in 5m* 5m grid pattern. Boundary corners were determined using DGPS. Surface Samples was collected from Block area for laboratory analysis. Entire exploration work was completed in 1 week period. 8 | Page Vill: - Sonpari , Tal. – Palitana , Dist.: Bhavnagar . BLACK TRAP BLOCK – D AREA: - 04.16.00 hect. CHAPTER II GEOLOGY a) Brief descriptions of Regional Geology with reference to location of lease/applied area:- The physiography of the district varies from place to place. It ranges from the coastal marshes and sandy areas fringing the Gulf of Cambay (Khambhat) to the hilly areas of Palitana and Sihor in the south and southeast and Botad and Gadhada in the northwest. In the north-western parts of the district, hilly upland area ranges between 100 and 296 m above mean sea level (amsl) and the regional slope of the district is towards east in this parts. The height of the hill ranges in the south and southwest covering Palitana and Sihor talukas generally range from 305 and 457 m amsl.
