The objective of the proposed ILP Task Force is to provide a new framework for mineral exploration targeting. 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 first major aim of this proposed Task Force is to extend the WSM database with a quality ranked compilation of stress magnitude data. In addition, the current WSM database only compiles the stress data for the upper 40 km of the Earth’s crust to represent the crustal stress. However, most of the global scale geodynamic models need to be calibrated with stress data on the deeper part of the Earth’s lithosphere. Therefore, as the second major aim of this proposed Task Force, we will systematically compile the lithospheric stress data.
The objective of the proposed ILP Task Force is to coordinate the Global Heat Flow Data Assessment Project in order to provide a quality controlled, authenticated global database of heat flow values and other thermal data. This project supports the International Heat Flow Commission (IHFC) whose mission includes promoting geothermal research and maintaining and disseminating the Global Heat Flow Database to the global community of Earth Scientists. To this end, screening, assessing and updating of each data entry compiled in the Global Heat Flow Database since 1939 is required. All project collaborators contribute with the revision of selected papers in this process.
The main scientific objective of the proposed ILP Task Force is to collect and assess quantitative data on the first two-billion years of well-preserved geological records from the North China, and Pilbara Cratons, the ancient section of the Kaapvaal (Barberton and Ancient Gneiss Complex), and the few scattered Eoarchean crustal fragments, to place quantitative constraints on the timing and mechanism of the initiation of plate tectonics. This study will provide new insights into how the planet responded to a decrease in heat production, loss of heat from accretion, and decreasing energy from orbital dynamics.
