1 . Geology Description <br /> .:_ 1 . Description of geolog_r of the area to be aff cted <br /> over the life o= the mine <br /> a. General statement <br /> The coal deposits mined by �_id-Continent ' s - <br /> Coal Basin operations occur in the Mesay.erde formation. <br /> dating . from the Cretaceous period of the Mesozoic era . Two <br /> seams are mined , the "B" bed and the ",fiddle" bed . Two <br /> other coal seams in the 114asaverde formation have also beer- <br /> evaluated and are considered uneconomic to mine utilizing <br /> current mining methods . They are the "A" and "Plac:ita" <br /> beds . <br /> Mid-Continent operates a complex of give <br /> mines in the two developed seams or beds . dines No . 1 , 3) , 4 <br /> and 5 are in the B bed and nine No . 2 _s in the fiddle bed . <br /> The B bed is lower . It, lies approximately 450 ' beneath the <br /> diddle bed . <br /> b . Geologic structure (See Geology Map at <br /> Exhibit III-C-1) <br /> Mid-Continent ' s Coal_ Basin operations are <br /> situated in a northwest-trending , eliptical anticline of <br /> some 26 square miles in size , *,which is rimmed 'by outcrops of <br /> ti:e coal-bearing Mesaverae =ormation . The ii?ne portals are <br /> located on the :Jest and southwest- sides of the basin , :with <br /> the coal procassing plant beside Coal Creec:, in the approximate <br /> center oL the basin. <br /> ifining during the life of _h` operation ?gill <br /> i C:ilvT.w the B and 2-fiddle beds beneath the divide of the <br /> w <br />
