WebA sandstone with more than 15% silt or clay is called a wacke (pronounced wackie). The terms quartz wacke, lithic wacke, and feldspathic wacke are used. Another name for a lithic wacke is greywacke. Some examples of sandstones, magnified in thin section are shown in Figure 6.7. (A thin section is rock sliced thin enough so that light can shine ...

Weblithic arenite, sandstone ( i.e., sedimentary rock composed of grains 0.06–2 mm [0.0024–0.08 inch] in diameter) containing over 50 percent rock fragments. Lithic arenites most often are of gray or salt-and-pepper colour because of the inclusion of dark rock fragments, mainly slate, phyllite, or schist but also andesite or basalt. WebThe developed algorithm has been efficiently applied for thin section analysis of sandstone. It has showed not only high agreement with manually processed thin sections and tremendous working time optimization, but more consistent results of segmentation as well.
