Create a realistic depiction of torbanite found in a dry geological stratum. Torbanite, a precursor to coal, forms in waterlogged forests but can also be found in dry geological layers. For this image, depict a dry geological environment with layers of sedimentary rock, shale, or sandstone. Showcase torbanite deposits within these layers, emphasizing the compressed and organic nature of the material. Use lighting and shading to accentuate the texture and appearance of the torbanite, highlighting its unique features such as its dark coloration and organic composition. Aim to create a photograph that accurately represents torbanite as it appears in dry geological strata, while maintaining a high level of realism. --s 250
