Create a realistic photograph depicting lignite found in a dry geological stratum. Lignite, also known as brown coal, is a low-grade coal formed from compressed peat. For this image, depict a dry geological environment with layers of sedimentary rock, shale, or sandstone. Within these layers, showcase deposits of lignite, emphasizing its brown coloration and organic composition. Use lighting and shading to accentuate the texture and appearance of the lignite, highlighting its unique features such as its fibrous structure and uneven surface. Aim to create a photograph that accurately represents lignite as it appears in dry geological strata, while maintaining a high level of realism. --s 250
