May 10 and bit slow start to fieldwork in Finland ๐ซ๐ฎ โฆ
But we need a photo from the field: #FridayFieldPhoto 2/2024!
One more pick from Cabo Verde ๐จ๐ป!
Columnar basalts are so cool ๐๐๐คฉ!

The #EGU24 is here and I present a poster of our studies at Kopparnรคs site Please drop a visit at the poster if you are interested in site characterization of a fault zone.
Poster | Wednesday, 17 Apr, 16:15โ18:00 (CEST), Display time Wednesday, 17 Apr, 14:00โ18:00 Hall X4, X4.127
Conglomerates at beach.
Layer of conglomerates in sandstone.
March 1 and we are finally back with a #FridayFieldPhoto 1/2024!
Fieldseason is approaching fast and first up some spectacular structures from Cabo Verde ๐จ๐ป! The conglomerates are really something ๐คฉ!

The Nordic Geological Winter Meeting 2024 was a success with around 350 scientists on site!
I had the opportunity to present our recent study of fractures & faults with associated alteration in the almost 2 km deep drill hole.
The meeting was a perfect venue to discuss hot topics in Geology!

Hi Dani,
The Research Gate profile page has probably the most comprehensive record of my papers and research:
www.researchgate.net/profile/Jon-...
The shift from X towards the more blue horizon happens next year. Will be posting more here less there
If you are interested for face to face discussions concerning all aspects in structural geology keep your eyes open for the following conferences NGWM24 and EGU24.
First some tranquility ๐๐ฅณ๐พ๐บ!

It was a great pleasure today to have a talk about our projects FLOP and Deep-HEAT at the Norwegian Geological Survey! Great discussion and extremely important to share knowledge and experience to enhance understanding and research.

Friday Feeling comes with Friday Field Photo. This photo comes ftom one of the nicest outcrops in ๐ซ๐ฎ the Kopparnรคs site in S Finland.
Follow my posts for more geological posts and especially structural geology.
This photo shows a shear zone with prominent mylonites.
