PHYSICAL AND INDEX PROPERTIES OF LATE PRECAMBRIAN AND CAMBRIAN SALT RANGE ROCKS OF PUNJAB
Abstract
Thirteen rock types including Sandstone, Siltstone, Dolomite, Shale, Gypsum and Rock Salt collected from five different formations of Salt Range area of Pakistan were tested to assess their physical and index properties. Specific gravity, dry and wet unit weights, moisture contents, porosity, water absorption and slake durability index were determined. Results indicate that most of the rocks have their specific gravity and unit weight values in the standard range. Higher durability indices and low water absorption values of sandstones and dolomite make them suitable for construction materials. While higher porosity of Baghanwala sandstone, lower and upper Khewra sandstone indicates their potential as hydrocarbon bearing reservoir and at the same time make them an ideal candidate for greenhouse gases sequestration in the subsurface.
