Type of structure Local
Structure description The Structual Control That Influenced The Deposition Of Asbestos At This Extreme Distance From Diabase Has Not Been Definitely Determined, As No Dikes Or Crosscutting Features Are Indicated. These Are Numerous More-Or-Less Parallel, East-West, Pre-Mineral Fractures Showing Slight Horizontal Movement, Which May Be Related To The Ore Deposition
