This area is naturally divided into three districts, which, from the important centers of manufacture, are named : The northern or Blue Rapids area in Marshall county ; the central or Gypsum City area in Dickinson and Saline counties, and the southern or Medicine Lodge area in Barber and Comanche counties.
Seite 62 - I have traced this gypsum belt from the Canadian river in a southwest direction to near the Rio Grande in New Mexico.
Seite 96 - County, near Gunnison; in the eastern part of Washington County (?), between Duck Lake and Rockville, and at other places. Recently enormous deposits of gypsum have been reported from Iron County, at points so far from lines of transportation, however, as to render their exploitation impracticable for the present.
Seite 49 - From an examination of a map of west central United States, with the gypsum deposits indicated thereon, it will be seen that if the northeast line of the Kansas deposits is extended it will strike the Fort Dodge area in Iowa, and if it is continued to the southwest it will strike the extensive deposits of the Canadian river in Indian territory and those of Texas. TOPOGRAPHY. NORTHERN AREA. The phrase " low monotonous prairies of Kansas " has no application to the gypsum belt, for there this feature...

They are all of the rock-gypsum type, except the one near Fillmore, which is in the secondary form of unconsolidated crystalline and granular gypsum blown up from dry lakes into dunes.
Seite 99 - In places veins of satin spar, as thin as a sheet of note paper, or even an inch in thickness, can be traced for many hundreds of yards upon the surface of the ground in uninterrupted course, except for intersecting planes of the same material. On the walls of the ravines and canyons places are seen where spar veins cross and recross each other with bewildering profusion. * * * Gypsum in all varieties may be found within a short radius.

Seite 93 - ... gypsum are here exposed and the marls are alkaline and saline. We have therefore local proof, as well as the most conclusive evidence from the environs, that the whole of the plain is in or near the horizon of gypsum and salt that separates the lower from the middle member of the red or saline series. In the salt flats the ribs of gypsum rise in successive ridges, and the action of the elements soon breaks up the exposed crystals into small grains which are carried by the winds hither and yon....
Seite 50 - In 1894 the company abandoned this quarry, and sank a shaft a quarter mile west of the quarry, 80 feet in depth, to the lower stratum, which is nearly 14 feet thick. The rock is white, though much of it is traversed by wavy dark lines which lie close together, giving an appearance somewhat like granite or gneiss, so that plaster made from it is called by the company
Seite 34 - State, says: At various other points gypsum is found in the outcrops of the formation, and notably in the vicinity of Sylvania, Lucas County, while in the deep wells recently drilled through northern and central Ohio it is the exception to miss deposits of gypsum in the samples of drillings. The last case reported is 3 feet of pure fibrous gypsum from a depth of 150 feet at Upper Sandusky.
