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

DIVE has completed logging
19 Dec 2022
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.
Last Logging Campaign at Drillsite 1B
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.
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.
