Soon we will leave the Seve Nappe rocks behind us ...
This core run might contain the first rocks from below the Seve Nappe.

Soon we will leave the Seve Nappe rocks behind us - that’s at least what we hope after studying the last couple of core runs. First signs of less strained and less metamorphosed sediments appear, after drilling almost 150 m through mylonites/mylonite zones - what we think is the central part of the thrust zone below the Seve Nappe. Looking backwards (or upwards), we can state that the thrust zone most likely already began somewhere between 2000 and 2050 m - i.e. has a thickness of about 300 m until now and we are not through it yet! That’s the conclusion from the drill site - the real work to define, study and characterise the thrust zone in detail will of course follow off-site. At present we really have the thrill to drill - what will we find below? Särv oder Jämtlandian Nappe(s) rocks?
