A Study Of The Subsurface Stratigraphy Of The Upper Cambrian In Western Missouri, Joseph L. Thacker Jr.
A Study Of The Subsurface Stratigraphy Of The Upper Cambrian In Western Missouri, Joseph L. Thacker Jr.
Masters Theses
"Megascopic examination of diamond-drill cores supplemented by insoluble residue data provides a usable means of studying the lithologic characteristic of Upper Cambrian strata in the subsurface of western Missouri.
The stratigraphic relationships within each Cambrian formation and the relationships of each Cambrian unit to formations above and below are discussed.
The relationship of Upper Cambrian strata to the Precambrian surface in western Missouri and easternmost Kansas is illustrated. The Lamotte Sandstone is overlapped by the Reagan Sandstone against Precambrian topographic highs and the Bonneterre and lower Davis are replaced by sandstones similar to the Reagan in southwest Missouri and southeast …
Mercury Distribution In A Massive Sulfide Ore Deposit At Balmat, New York, David Ray Jessey
Mercury Distribution In A Massive Sulfide Ore Deposit At Balmat, New York, David Ray Jessey
Masters Theses
"Ore samples consisting of diamond drill core and mine samples, collected from several Balmat ore bodies, were analyzed for their mercury content. The average contents in these ore bodies were found, in ppb, to be: Upper Gleason, 829; Middle and Lower Gleason, 504; Loomis, 546; Fowler, 195; No. 1 Zone, 37; Sylvia Lake, 59; No. 2 Mine, 5. If all of the mercury in these pyrite-sphalerite-galena ores occurs in the sphalerite, then the average sphalerite mercury contents, in ppb, are the following: Upper Gleason, 2490; Middle and Lower Gleason, 2516; Loomis, 2701; Fowler, 1376; No.1 Zone, 384; Sylvia Lake, 408; …

Interpretation Of Imagery Lineations, Logan Creek Area, Southeast Missouri, Gregory Paul Smith
Masters Theses
"Depletion of ore in Missouri's old lead districts and the opening of the state's new lead district adds impetus to understanding and delineating geologic structure in and adjacent to the new lead district. Image and geomorphic analysis, hydrologic data, and subsurface structural contour mapping are used in interpretation of geologic structure in Dent, Shannon, Reynolds, and Carter counties, Missouri. Unlike the time consuming surface geologic mapping, the modes of investigation used in this study enabled the writer to make a larger, regional-scale study with results comparable to those attainable by surface mapping. The area is covered by thick residual soils …
