JimB88 Posted November 20, 2011 Share Posted November 20, 2011 Thats neat Steve..That looks to be an active quarry/mine; do they allow the public in? Over here many places no longer allow it do to liability. Link to comment Share on other sites More sharing options...
Terry Dactyll Posted November 21, 2011 Share Posted November 21, 2011 Jim... They have just filled it in now and are currently putting the subsoil back on... They did let the odd geology group in now and again but usually its no access for the same reasons you suggest... although I got straight in and me and a friend have had the place to ourselves for 3 years...

glacialerratic Posted March 30, 2012 Share Posted March 30, 2012 Those shots of the quarries in the SE., wow! I took a trip to the closest limestone outcrop to me, in NW. Lower Peninsula, MI., which is the type locality for the Whiskey Creek Fm. It is about 80 miles to my north, in Charlevoix Co., near Norwood. I did not find much in the way of fossils, just a couple of pieces of favosites. It is a MI. State Park, so this was a "see some bedrock" trip, which is a rare treat in my neck of the woods. This is a U of MI. Ann Arbor field trip stop, and is listed in the Devonian Strata of Emmet and Charlevoix Counties, MI. -- http://hdl.handle.net/2027.42/48608 The main outcrop (a series of 3 small bluffs) is right on the beach, and contains pretty cool chert beds. Showing the chert bed in dolomitic limestone: A colorful chert nodule: There are fossiliferous beds, but I could not locate them. The field trip guide was done in 1974, so a lot has changed in that time. There are several houses in spots that correlate with a locality stop.

glacialerratic Posted March 30, 2012 Share Posted March 30, 2012 (edited) Up from the beach, a very rough 2-track parallels Lake Michigan. In one large "puddle" there is an outcrop of the black Norwood Shale. It was kind of funny finding an exposure in the road, it was only about 2' high. There was a lot of loose shale pulled up by vehicle traffic, so I grabbed a few of those. No pics of the mud puddle. Along the road are the upper beds of the Whiskey Creek Fm., except they were all broken and weathered. We found a small stream bed, and took some shots: There were a lot of limestone blocks showing (oscillation) ripple marks, and seems to correspond with unit 51D in the strata guide: All in all, a very interesting area. I was amazed by the amount of surface water moving to the lake. Below the limestone is the Jordan River Shale, that extends into the lake. It is a very hard shale and must keep the water from perking through. Edited March 30, 2012 by michigantim Link to comment Share on other sites More sharing options...

Missourian Posted March 30, 2012 Author Share Posted March 30, 2012 The Pennsylvanian strata at I-435 and Holliday Drive are well known to Kansas City area collectors. The exposures are quite imposing: From bottom to top, Raytown Limestone, Liberty Memorial Shale, and Argentine Limestone: The Liberty Memorial here has produced some excellent crinoids, including many crowns. Unfortunately, overburden from above has covered most of the productive level. From bottom to top, Frisbie Limestone, Quindaro Shale (both just above the talus), Argentine Limestone, Island Creek Shale, Farley Limestone (limestone pair in middle top), Bonner Springs Shale (nearly hidden from view), and Spring Hill Limestone: The Argentine, a little closer: This unit is about 20 to 25 feet here. The prominent bed at top contains many brachiopods. You have to wait for chunks to fall down to get at them: Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted April 1, 2012 Author Share Posted April 1, 2012 Winterset Limestone, Pennsylvanian Clay County, Missouri The lower part of the unit is made up of thick beds. Plant root molds are commonly present in the upper part: The upper beds are thin to medium-bedded limestones alternating with shale partings. The upper beds are usually barren, though Cordaites leaves can be found: In other spots, a mollusk-bearing oolitic limestone occurs in the upper part. Context is critical.

Missourian Posted April 22, 2012 Author Share Posted April 22, 2012 Bethany Falls Limestone through lower Winterset Limestone, Pennsylvanian Near downtown Kansas City, Missouri I've seen this exposure hundreds of times from the nearby interstate, but I hadn't checked it out until now. It consists of the upper Bethany Falls Limestone, Galesburg Shale, Stark Shale, and lower Winterset Limestone. The shales are mostly covered. There aren't too any fossils to find in this exposure, but it does serve to show the character of these beds far from their usual outcrop area. Very old quarry: Full quarry wall: These three thick beds are characteristic of the lower Winterset: The exposure is behind the hundred-year-old Imperial Brewery building: The stratigraphy of this outcrop is described in "The Geology of Jackson County" (1917).
