Trip to Northern Poland – Goths and Oil

Hello! I hope you are enjoying your holiday time.

This year I decided to stay in Poland and travel North to the Baltic Sea area. That was fully recreational trip and I wanted to share with you with couple of views from that region.

Although Baltic Sea region is known in Poland from its unpredictable weather and people rather perfer to go to Croatia or other more sunny places it is really great place to visit.

I was traveling from Warsaw to the Baltic shore and then came back through the region called Kaszuby (Kashubia). This is another area which is worth seeing when you are tired from the crowds and atmosphere of more popular vacation locations. There are lots of lakes and forests. Sometimes this region is called Kashubian Switzerland.

Probably that would be very long story to write about all the places worth seeing in the Baltic region and Kashubian region so I will focus on Geology:)

 

Region of Kaszuby is rather known from the post glacial relief and surface forms typical for Pleistocene. You can’t spot any outcrops of the basement rocks, everywhere are sands and clays but also very beautiful post-glacial lakes and hills. One example of ‘hard rocks’ are granites carried by the glacier from the North 20.000 years ago. You can see those rocks everywhere in the crops and forests. People used those stones for many purposes but one of them was especially fascinating.

In the village called Węsiory situated close to Kościerzyna and Kartuzy towns you can find strange rings and graves made of stones hidden deep in the forest. Stone rings have around 5-8 meters in diameter and graves are about 0.5 meter high domes. There are couple of rings (around 5) and much more graves (probably about 100).

Most likely that was the place where Goth tribes celebrated their religious rites around 2000 years ago! There are couple of rings in the forest reflecting one of the constellations. It is amazing how people were able to observe stars and understand astronomy 2000 years ago.

On the trees around you can notice warnings giving examples that taking one of the stones home as a souvenir or destroying the rings will bring you bad luck and turn the energy against you. Those are really scary stories:)

So…that was more archeaological story then geology but still there are rocks in it.

Another place which is much more related to geology is Żarnowiec. Small village in the North but very famous in Poland. In 80’s that was the place where first Polish nuclear power plant was planned to be built. Construction begun and was in progress and then Chernobyl disaster happened in 1986. As Żarnowiec power plant was planned to be the same type construction was stopped and later abandoned. Now there is construction site left and you can see it at your own risk (1. there is security, 2. probably it is dangerous as every not finished and not secured construction site). Another thing, much less known, is that Żarnowiec is a place where small oilfield was discovered in 70’s and oil and gas are produced until now. Dębki, Żarnowiec and Białogóra villages are the places where the only small Cambrian onshore oilfields were found in the Baltic region. Much more fields were discovered later offshore in the Baltic but in the same formations (Cambrian) and most likely on the same Łeba block. In many publications there are much more structures/traps visible offshore so you can imagine what potential is still there.

Couple of years ago I was trying to model the burial history of this area. Not sure if it was done right but on the image you can see the Łeba block (black arrow) and very deep burial zone close to the T-T zone on the left (West) with often cooked organic matter and very stable crystalline craton on the right (East) with generally immature sediments.

Payzone is quite deep, around 2700-3000m in Cambrian sandstones interbedded with siltstones. Today totally 8 wells produce around 5 tonnes of oil daily (~40 bbl/d) from those formations. Those are not huge resources but since production started approximately 46.000 tonnes (363.000 bbl) of oil and 38.000.000 cubic meters (~1.3 Bcf) of gas were produced not harming the environment with industrial landscape but also assuring local people work places for many years.

Now in Żarnowiec village you can see the monument comemorating the fact of the oil discovery: pump jack and information plate.

As you can see wherever you will go on vacation geology will assist you and also looking at small oil and gas discoveries made in 70’s and 80’s you can think of the potential of those basins which is still not fully discovered.

P.S.

On my way back huge storm invaded the region so there were even more attractions caused by the nature:)
