Barite nodules in Devonian shale and mudstone of western Virginia. Bulletin

Technical Report ·
OSTI ID:7016282
;
The objectives of the study were to locate and describe the barite occurrences in shale and mudstone of western Virginia and to find out whether the geochemistry of the shale and mudstone, together with the physical features of the nodules and enclosing rocks, would help determine if the nodules had been formed by submarine spring activity in the area or if they had originated in some other way. The report describes the barite nodules, presents the results of chemical analyses of the enclosing shales, and describes the depositional environments in which the barite nodules formed. The report evaluates the features of the nodules and enclosing rocks and suggests a feasible model for the origin of the observed features.
