Análise das principais rochas ornamentais produzidas no estado do Ceará de acordo com o potencial de mercado e características geológicas

Abstract

Ceará has a geological conditioning and a great geodiversity that favor the presence of rocks for ornamental and cladding purposes. In recent years, due to the diversity of types of rocks with different typologies existing in Ceará, the state has stood out as one of the main mining centers and the third largest exporter of ornamental rocks in Brazil. However, there is a lack of information regarding the materials that are produced in the state and their individual characteristics. In this sense, it is necessary to know its characteristics and properties for possible studies and projects that contribute to the development of the sector. In view of this, the present research aims to analyze the main dimension stones produced in Ceará in accordance with the market potential and geological characteristics. Therefore, the work was developed in three stages, the first consisted of selecting the main companies producing dimension stones in Ceará, the second analyzing the market share of these companies and, finally, identifying and describing the main materials sold by these companies. . It was verified, through the mineral production yearbooks of Ceará, between the years 2014 to 2018, that the main companies producing dimension stones were: Vermont Mineração, Granistone, Vulcano Export, Quartzblue Mineração and Mineração Agreste. Among these companies, Vermont Mineração is the one that recorded the largest share in the commercialization value of mineral production in Ceará, occupying more than 50% of the ornamental stone market in the state. The main materials produced and marketed are the Taj Mahal (Vermont Mineração), Perla Venata (Quartzblue Mineração) and Perla Santana (Mineração Agreste), both rocks geologically classified as quartzites.
