Went out for a little drive today and took the digital camera...



This is a road cut located immediately to the south of Louisville very near Bardstown, Kentucky. <Geology Lesson> In the background, you will notice several laminations of a very fossiliferous limestone interbedded with some layers of heavily weathered shale. The fossil hunting in this area was nothing short of spectacular as I brought home several brachiopods and some other bivalves. The plant fauna was generally not present at this road cut which indicates a very nutrient rich, shallow sea that formed this sedimentary structure. Most likely of the Mississippian Era.



Same road cut; different perspective. In this photo you see a few of the larger, more prodominant sedimentary structures. Also, if you'll look closely, you can see where the vadose/phreatic zones converge (water table). Notice the 'wet look' immediately below one of the layers of stratigraphy. Oh yeah... there's also a pretty truck in there...



Again, same road cut; different vantage point. Please note the incredible 2001 F-150 King Ranch Edition Supercrew in the foreground. The background shows a little different view of the vadose/phreatic zone conversion. Also, in this photo, you'll notice the youngest rocks (top) are generally weathered where dissolution has proven to be the dominant form of errosion before and after the rock was blasted.

Just thought I'd share a little bit of a geology lesson along with showing off a few pictures of the truck. If you have any questions/comments, don't hesitate to post or email!

nice truck...a little bored were we

Joe

 

LMAO..... I was hoping no one would notice how bored I was... HAHA! The road cut was pretty cool... lots of nice fossils but, yup, you hit the nail on the head... I was bored.

LOL!!

But, I do have a lot of new photos in my galleries thus, go check them out!

Link in sig line!

Thats a nice change in the signature also Rockpick, the other one was pretty cool also, but this one is awesome too.

 

Thanks Greenbuck...

 

Looks nice!!!!



I remember when I took Geology a few semesters ago we went and looked at different things in the arbuckle mountians. It was cool it identify all the features. Forgot most of the names, but still recognize some of them if I see them.

 

Yeah, it's a pretty cool science. I don't use much of my 'rock geology' though in my line of work. It's more soil classifications and such as we are rarely coring rock or drilling rock wells around Kentucky.

Environmental contamination typical originates from an underground tank or a surface spill and thus, doesn't typically affect underlying rock aquifers however; some do...

I do have a dry cleaner site that is pretty interesting in that the contamination there is what's known as "DNAPL" (dense non-aqueous phase liquid) and is generally dry cleaning fluid (PCE/TCE). Long story short, the contamination has migrated into a rock aquifer and now the 'powers that be' want the site remediated. There are few techniques available to deal with this type of contamination thus, we're having to be creative in dealing with the problem.

I think the chosen method is going to be to oxidize the material in place and thus, make it inert. This involves the injection of a peroxide material along with a catylist of Fe III ions. I hope it works... it's not cheap.

all of the Geologists in Oklahoma are all concerned with Oil and gas wells for the most part. I did get to ride in one of the large sizemograph (sp?) machines. The opperator said it was one of the 4 of the largest in the world. Put a large platform on the ground and shook a bit, and went on. I was small so it was awesome.

 

Yeah, definately the oil and gas to have there but, I assure you that there are a hefty amount of geologists out there chasing environmental contamination too... The money is in the Oil & Gas... the pee-on geologists chase the oil after it has leaked out of a tank... *shrugs* Call me a pee-on.

I just can't seem to ever get bored looking at picture of the babies!

 

This is great......you can't quite see the licence plate on your truck so as far as my own collection of pictures that I occasionally show to friends goes..... MY truck has just been to a whole lot of new places !!!!

Thanks very much....keep 'em coming.

I'll save a whole bunch on petrol (sorry....gas) the next time I come over !

 

Lenny,

Note one very unique difference... you have a 4X4 and, as Skagel would call it, I have a wussy 4X2. LOL!

RP

 

OK, RP, my question is, wouldn't "north of Louisville" be in Southern IN? And if I recall correctly, Bardstown is south of Louisville. Just curious, as I was in Louisville last Thursday and Friday. As for the fossil things, you can keep those. I like looking at them but that's about as far as I go.

 

LMAO.... whoooooooooooooooooops...


That is correct 6, it would be directly south of Louisville.

Nevermind that I was working on beer #4 at the time of that post...


I'm a bonehead.

Rockpicks made a mistaaa...ake !

I have a wussy 4x2 also.

Whereja get the idea I had a 4x4 ?
