Exterior door trim The light gray, faintly mottled limestone that frames the door contains whole fossils, fossil fragments, and pellets. It was originally a shellsand deposit like the Salem Limestone. Unlike the Salem, this limestone is not visibly porous; calcite cement has filled all the spaces between grains. Consequently, it takes a polish.

 · Salem Limestone. Grain Shape: Subrounded. Rounded. Grain Sorting: PoorlySorted. Grain Size: Medium. Petrographic Description: Specimen . This is a fossiliferous limestone. The limestone is grain supported and has a sparite cement matrix, much of from syntaxial overgrowth. Allochems constitute about 85 percent of slide area. These criteria identify the limestone as a .

CALCISPHAERA FROM THE SALEM LIMESTONE 1155 plays a hexagonal peripheral outline. A fairly common form is one formed by alternating layers of microcrystalline calcite and translucent, radially oriented calcite. Orifices.Most Calcisphaera from the Salem appear to lack any type of orifice in thinsection. Plate 144, figure 13, however,

In cores and well records, the Salem Limestone was found to consist of coarsely crystalline, oolitic limestone with fragmented fossils and saccharoidal dolomite, dolomitic limestone, and chert. The distinctive salmonpink, semiopaque, and darkgray chert commonly found in the Salem in the subsurface of eastcentral Kansas (Lee, 1956) was found only sparingly in samples from wells in .

Several aspects of Salem Limestone combined to make everyone from Odd Fellows to opera fans incorporate the stone in their structures. Stone masons can cut, plane, flute, and carve the Salem easily and in all directions and once shaped, Salem hardens over time. It splits evenly, and in any direction. When rock had to bear the weight of a building, Salem excelled because of its low ...

SEDIMENTOLOGY OF THE SALEM LIMESTONE IN INDIANA NED M. SMITH Department of Engineering Geology, Purdue University, Lafayette, Ind. ABSTRACT The Mississippian Salem Limestone, from which dimension stone is quarried in Indiana, is principally a calcarenitic rock formed of fossil bryozoans, echinoderms, and specimens of Endothyra. Numerical associations of the fossils, .

Minor lithologies in the Salem include biocalcilutite, biocalcirudite, sucrosic dolomite, dolomitic limestone, finegrained limestone, fossiliferous crystalline limestone, sandstone, chert, and the evaporites anhydrite and gypsum. Some finegrained, silty, dolomitic beds weather yellow and form reentrants on the weathered faces. The Salem differs from the underlying Ullin by having a greater ...

formed white sand on the ocean bottom. Waves and storms agitated this sand; clay and other mudsized material was removed, and larger shells were broken up into smaller fragments. The sand also swept up into bars that stacked atop each other over time. Once cemented into rock, the result was the Salem Limestone, an exceptionally pure, finegrained, and very uniform limestone. The uniformity ...

Indiana Limestone (geologically known as the Salem Limestone) is essentially a monomineralic rock consisting of the calcium carbonate (CaCO 3) mineral named calcite. The calcite comes from the skeletal material (about 75 percent) that form the framework grains and from the cementing material (about 20 percent) that binds the grains together. Porosity (about 5 percent) and small amounts of ...

 · Known the Salem Limestone, this geological formation is a uniform outcrop of pale stone that lies directly beneath the surface of much of southern Indiana; in some places, it reaches thirty meters in depth (Ambers 246). The shape of this limestone formation, together with that of the siltstone that intermingles with it, is responsible for the unpredictable landscape of my home. Bloomington ...

Salem Limestone "dwarfed" fauna (Mississippian, Meramecian) of central Indiana. Most valves are of Pterochiton parvus (Stevens); this littleknown species is redescribed, illustrated for the first time, and neotype specimens are designated. One new species, Pterochiton elevatus, is also present in small numbers; it appears to be closely related to P. parvus. The ratios of head, intermediate ...

 · Salem limestone, like all limestone, is a rock primarily formed of calcium carbonate. The limestone was deposited over millions of years as marine fossils decomposed at the bottom of a shallow inland sea which covered most of the presentday Midwestern United States during the Early Carboniferous or Mississippian Period which lasted for 40 million years, from 359 to 318 million years .

The Salem Limestone (Cumings, 1901, p. 233) is named for Salem, Washington County, Indiana, where it is extensively quarried for Indiana building stone. It was called "Spergen Hill" or "Spergen" limestone in early reports. Type Section. No type section was designated, but a quarry mile east of Salem is considered the principal reference section (Shaver et al., 1970). Extent and Thickness ...

Sinkholes are formed when largecircular caves in the limestone collapse. The small group of sinkholes in NE LowerMichigan is only part of a larger karst system extending eastward to Lake Huron. Karstrefers to a limestone region with many sinkholes, abrupt ridges, caverns, and disappearingand underground streams. Some sinks, like Shoepac Lake, are filled with water while othersare dry. The ...

Indiana Limestone The Salem Limestone, or "the Salem," is the stone referred to as Indiana's most famous limestone. The Salem limestone is "exposed in a narrow area that extends from the southern tip of Harrison County on the Ohio River northward to near Greencastle in Putnam County. Most of the stone suitable for use as dimension stone and for building purposes is found in Owen ...

Bedford Limestone: This sedimentary rock is formally known as the Salem Limestone, but also simply as Indiana Limestone. It is quarried in south central Indiana between Bloomington and Bedford. It was originally deposited in a warm shallow marine environment during Mississippian time (320360 million years ago). The fine oolitic texture would suggest the sediments were subjected to wave action ...

It is more finegrained and more closely cemented than the Salem Limestone. Some of the beds are shaly and some contain nodules of chert, a hard flinty material. Among the fossils that are abundant in some beds are colonial corals, such as Lithostrotionella. Observe but please don't collect specimens in the park.
