Drilling the Ivrea-Verbano zonE

Project Acronym: DIVE | State: Operational Phase | Expedition ID: 5071

Preparing a full drilling of the continental lower crust into the Moho transition zone in the Ivrea-Verbano Zone (IVZ) in the Southern Alps in Italy. The IVZ provides a unique and continuous set of geochemical, structural, and geophysical data on the nature of the continental lower crust and the crust-mantle transition, the construction and organisation of a deep crustal magmatic system, and the physical conditions (i.e. magma fluxes, magma/country rock rheology, density, seismic velocities). Drilling will additionally investigate heat production and distribution of heat producing elements across a continuous, finely banded sequence of lower crustal rocks, major pre-Alpine and Alpine crustal shear zones, present-day alteration processes, fluid compositions, and its relationships to the major orogenic fault structure of the Alps, the Insubric Line.

Keywords: Europe, Italy, continental crust, Moho transition zone, seismic structure, rock physics

MoD: DIVE has completed logging and cleared the science part of site 5071_1B by Sunday December 18th. It then required a local heavyweight roadshow to pick up a single GFZ-container today. The entertainment was free of charge for innocent observers. The borehole will be properly sealed for the coming weeks, until site restoration early next year.

Logging and blogging. These are the remaining two activities at site 5071_1_B. The borehole is now fully accessible and logging has started, with the plan to finish all the program by Sunday, with active participation of GFZ/OSG, MU Leoben, Uni Lausanne, and several other university partners.

DIVE finished drilling first borehole

10 Dec 2022

Today the DIVE drilling target 5071_1_B in Ornavasso has finished the drilling activities, and the borehole has reached 578.7 metres depth below surface. The final images of the day show the bottom of the last core!

New Rig Arrives at Drill Site

MoD 28 Nov 2022

The day plan included a rapid change of rigs, which ended up taking the whole day. Nevertheless, the new, strong and blue PSM-16GT rig became operational in the late evening, and a night-shift crew left from the side of their beds to pick up work and hopefully new cores, restarting from 465.4 m depth.

Night Shift

MoD - 26 Nov 2022

Reaching 465.4 m depth by tonight, the day was spent with efficient core processing and packing. Plans: change of crew tomorrow, change of rig the day after. There is less and less light, and more visible stars ( photo: Luca P.)

Reached 200 m

31 Oct 2022

We have broken 200m and settling into a consistent drilling pattern. A happy team of Drillers and Scientists (31 Oct 2022)
