Since that time, however, reliable statistics do indicate that 3.1 billion short tons of limestone having a present value of about $17.5 billion have been mined in Missouri from 1920 to present.Limestone and dolostone are collectively referred to as carbonates because these two sedimentary rock types consist mainly of the minerals calcite (CaCO3 ), aragonite …MARBLE, LIMESTONE, and DOLOSTONE (See also FOSSILIFEROUS ROCKS TRAVERTINE entries.)

Black and white marble from Spain.Similarly, fractured dolostone with karst showed lower compressive strength values compared to fossiliferous dolostone. Not much variation was found in shale. Also, the JRC values for fractures observed in shale were very low as the fractures were planar without any appreciable roughnesses.

Answer to Question 11 pts Sedimentary Rock #1 isThe C3 orebody occurs close to the top of the fossiliferous dolostone unit and is laterally less continuous and thinner than the other two, but is otherwise very similar in appearance. Most of the manganese ores occur in a variable succession of poorly consolidated clastic sediments. The latter include laminated or massive clays, crossbedded ...View Lab 5 Introduction 2020.pdf from GLGY 471 at University of Calgary.
