Pipe Creek Jr. Reef, Pipe Creek Jr. quarry, Grant County (Silurian of the United States)

Also known as Reef 1431

Where: Grant County, Indiana (40.4° N, 85.8° W: paleocoordinates 26.3° S, 51.6° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Silurian (443.7 - 416.0 Ma)

• time subdivision given as Niagaran-Cayugan, or Wenlock-upper Ludlow

• formation-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; shelly/skeletal, gray, argillaceous grainstone and packstone

• fossils were collected from the flank beds of the reef; five lithologies were recognized: limestone, swirly limestone, dolomite and dolomitic limestone, silty mudstone, and interreef siltstone. 97% of the beds in the measured sections were limestone or swirly limestone. limestone described as white to gray, coarse-grained, and highly fossiliferous. swirly limestone described as argillaceous, characterized by milky while sparry calcite mixed with stringers and blobs of green silt to clay sized particles, medium to coarse-grained gray limestone and echinodermal debris

Collection methods: surface (in situ), chemical, peel or thin section,

• while not explicitly stated, it appears that fossils reported are those collected during field work in the quarry, not from state survey drill cores that were studied; fossils were collected in situ whenever possible, but the majority came from rock blasted from the SNW end of the quarry. This work was completed about one year after the quarry opened for business
