This romantic relationship tends to make the review of clays very vital for petroleum geologists. As well as this vital economic consideration, clays present important economic means for a wide variety of other industries.
After we perform with clay, we’re not only shaping a cloth; we’re connecting with the earth’s historical past. Each piece of clay carries the memory of volcanic eruptions, flowing rivers, as well as the slow passage of time.
