Hello this is the blogger antimonite. Ive decided to start blogging on geology in English again. But not here, since blogsome screws up so much. You can fins my new blog at sandbian.wordpress.com - Its newly started and will be about mostly geology from Sweden. Hope to see old and new readers!

From now on I will write all posts on geology on my blog Terra Incognita. And they will be in English. Please join me there and change or update your bookmarks or links to http://terraincognita.blogsome.com/. This blog is hereby closed for ever.

I noticed these strange formations on my vacation to the island of Gotland this summer and they baffle me. The stone is Silurian limestone. Anyone knows what they are? They are just too common to be random weathering. A trace fossil?

Oh you crazy Americans…:)

Im not sure what the correct English term is for it, but this is what I do for my final paper on bachelor level in geology. A petrological and mineralogical study av so called Battle axes (also know as Boat axes or axes from Corded ware culture, around 2900-2300 BC). The geological value of this is of study is limited to me learning a lot of methods for mineral and petrological identification - on a level usually more often found on a masters degree. The archaeological value of this study is to helt determine possible connections between different parts of the neolithical Europe based on what type of rock these axes are made of.I wanna learn all there is to know about petrological and mineralogical studies, so this is as good as anything else + the cool archaeological part.

Most typical axes of this type are made of diabase or basalt, found in many places in Sweden. But the ones Im going to examine (with thin sections and so on) are made of dacite, a dacite not found here. So if theres anyone out there with knowledge of European dacite locations, please let me know.

One typical battle axe, made of diabase (I think - the white spots seems to be dusty/eroded dents and cavities, difficult to say for sure). And no, of course we dont do thin sections of nice whole samples like this, but rather of broken up parts.

Take a look at these fairly new incredible photos from ISS. Link

Well, I didnt get around writing much yet about Swedish geology, and now there is that lovely Swedish version of the pagan ritual of midsummers eve coming up this Friday where Im probably going to get ridiculusly drunk and go of killing christians like a good old viking. But when I get back I will write some about my bachelor-project. Its to do with doing a petrographic study of a boat axe from the neolithic stone age. Stay cool and stay tuned! Happy midsummer - Glad midsommar!

I just recently came back from a week long trip to the province of Blekinge here in Sweden. Its an awsome province with beautiful deep forests and I can recommend a trip to it to anyone who loves nature. But be sure to bring something against mosquitos and ticks. The humid climate near the Baltic sea makes it a paradise for ticks.

It was a course in making maps of the bedrock, the petrology and structures. Mostly we found intrusive granites and more or less gneiss and granite-gneiss with pegmatite intrusions - the most common types of bedrock in here south east of Sweden. But one unusual loose rock caught our attention.

The theory my professor gave us was that it probably was a piece of diabas with (from the intrusion loosened) megacrysts of pegmatites in it (microcline and red quartz). The area is rich in pegmatites and diabase intrusions so the theory of origin made sence, however he had never seen anything like it before and had to base this on a qualified assumption. I presume its an unusal find or has someone found anything similar? No, its not my finger…

Just wondering if I still have any followers to the blog? I was thinking about starting up the blog with topics on Swedish geology for the summer. Mostly because of the severe drought in the Swedish bloggosphere during the summer time.

Let me know if Im still visible in the geoblog community!

Any experts on Cretaceous fossils from Ignaberga in Sweden out there that can help me? At that time, around 80 Ma it was a archipelago-like enviroment, rich on belemnites, brachiopods and shark) Ive got two small remains that I want to know what they could be.
