Advice wanted For Marble Area Description

I want to Know that is there any relation  of silica content in massiveness of Marble Deposits ?
i have a large land (http://maplered.com) in which there is a deposite found of dolomite with high silica % of 10-12 % and (http://maplered.com) on the topsurface sand (http://maplered.com) is there and (http://maplered.com) benith the sand (http://maplered.com) the deposite occur .
on the initial surface it is cherty and (http://maplered.com) as we go  deep  it is not that much cherty, there are natural cracks showing in the upper surface cherty Material (http://g654.org) . the area is plane land (http://maplered.com) not any hills . its on ground plane land (http://maplered.com) . and (http://maplered.com) after polishing the Material (http://g654.org) is taking ONYX like polish with some olive lining.
so please tell me that what is the general trend of massiveness of Marble (http://www.lightemprador.com) is it possible to get blocks with no natural cracks? is there any relation of silica with massiveness? this area is 1200 Meters in width and (http://maplered.com) 1600 Meters in length.
