Geologists use three main categories to classify rocks at the most basic level: igneous rocks, metamorphic rocks, and sedimentary rocks. Igneous rocks are formed as molten material (lava/magma) cools and solidifies. How long it takes this material to cool, along with the chemical composition of the melt, will determine the properties of the rock.Medium grey (N5). very hard tillite Medium dark grey (N4). very hard tillite Brownish grey (5YR 411), very hard quartzitic tillite Light to medium light grey (N6-N7), hard tillite. which disintegrates rap­ idly on exposure to the atmosphere Similar to 6681 but does not disinte­ grate as rapidly Medium grey (N5), very hard tilliteSedimentary rock types Conglomerates and breccias. Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix.Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts.
