Recent technologi-cal shifts and the depletion of mineral resources put pressure on the mineral exploration industry which is experiencing a boom in activity over the past decade. This boom is also asso-ciated with breakthroughs in mineral exploration which build on new fundamental results in geophysics, geochemistry, and geodynamics. Significant efforts are being put forward internationally and nationally, e.g. at the scales of national geological sur-veys, to bridge mineral exploration and the academic com-munity. However, the results of the academic research are not used at full by the mining industry. On the other side, a significant part of the fundamental research does not target practical application of the results by the mineral exploration community and the step between the academic result and its possible application is often missing. New ILP Task ForceThe objective of the new ILP Task Force (2019-2024) is to provide a new framework for mineral exploration target-ing. This requires detailed knowledge on the lithosphere-scale structure, including detailed knowledge of the crust, together with the improved and enhanced understanding of the impact of various plate tectonics and mantle dynamics processes on the lithosphere composition and architecture. The new ILP Task Force will focus primarily on magmatic ore deposits on continents, which are mostly associated with large igneous provinces, continental collisional orogens, Pre-cambrian cratons, and paleo-subduction systems. Other tec-tonic settings, such as the Arctic shelf, may also be included as a sub-task of the new Task Force.Magmatic ore deposits are formed during crystallization of a magma. They are linked to magmatic processes associ-ated with either plate tectonic settings (collisional orogens and subduction systems), or with mantle hotspots and plumes (large igneous provinces); some may also be associated with large-scale impacts that cause intensive lithosphere heating and melting. All these processes create and modify the struc-ture and composition of the crust and the lithosphere mantle, and therefore can be recognized by high-resolution geophysi-cal models. Geological data combined with geochemical stud-ies provides constraints on geodynamic processes responsible for formation and deposition of ore deposits. These processes can be tested by numerical modeling which provides impor-tant constraints on the details of magmatic processes and their impact on the lithosphere structure and composition.ConclusionsThe goal of the new Task Force fits the mission of the ILP in:• addressing the connections between the deep Earth ore-forming processes, lithosphere structure and mineral de-posits at the near-surface;• building on interdisciplinary research which includes collaboration between geology, geophysics and geo-chemistry;• building on the integration of geophysical imaging of the crustal and upper mantle structure with tectonic re-construction of processes that form and modify the litho-sphere and with geodynamic modeling of these processes.We invite a broad international geoscience community to join us in the new ILP Task Force !NEW ILP TASK FORCE (2019-2024): LITHOSPHERIC STRUCTURE AND MINERAL RESOURCES Artemieva I.
