Hence, it would have been a valuable resource for a long time. Softness may be the result of a special geology. Dutch geologists have suggested that this is a deposit not derived from alteration of ultramafic rocks, which is by far most common mode of formation in Norway. Rather, it may derive from alteration of dolomitic limestone. There is only on other known soapstone deposit in Norway with such an origin. Here’s an account of this exciting quarry, also including a discussion of whether soapstone vessels from the quarry were exported to Denmark in the 9th century CE. Continue reading →
