Calcirudite is a type of limestone that is composed predominantly, more than 50 percent, of carbonate grains that are larger in size than sand (2 mm in diameter). The grains can consist of either fragments of fossils, fragments of older limestones and dolomites, other carbonate grains, or some combination of these.Jan 1, 2003 · The fundamental name is based on the four grain types and the relative abundances of grains (allochems), matrix, and cement or pore space. Eleven basic terms are generated (top diagram on facing page), including ones for pure mud rocks (micrites), muddy rocks with spar patches (dismicrites) and organically-bound rocks (biolithites). In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed.Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere.

Using this method for all calcarenite types, the saturation degree (Sr) was equal to 100% (Andriani and Walsh, in press). Complete saturation demonstrates that pores in the rock particle systems are interconnected and continuous.
