Small industries are among the things that society needs to employ young people looking for work, especially new graduates from engineering institutes and colleges, and from these industries that do not need a large capital, it is polishing rocks with special natural characteristics as colour, lustre, hardness ... and other, especially these materials available locally Emphasis was placed on the most important rocks with the required natural properties and their locations in the formations close to the surface or exposed on the ground, which can be exploited without high cost, Limestone and dolomite are the common rock types and usually occur in thick beds in the area of Jabil Nafusa Several samples tested for nodules type of chert to determine general physical characteristics and their relative quantities. The results reveal that although the secondarily re-deposited nodules provide a usable and easily accessible source, the quality and quantity of the chert nodules varies greatly and the test design must be thoughtful to determine the quality and quantity. As well as Geodes, which found in carbonates rock with different size, which generally occur in limestone, a calcium carbonate, or in dolomite, a calcium-magnesium carbonate. Emphasis was placed on the Nafusa Mountains (Jabal Nafusah) area (Nalut and Al Aziza Formations). |
