About Paper:

Continents and rocks provide critical insights into Earth's geological history. Through targeted drilling, we investigate fundamental geological processes preserved in the historical record. The COSC project focuses on studying the mid-Paleozoic Caledonide Orogeny in Scandinavia to enhance understanding of mountain- building dynamics across both historical and modern active mountain ranges. Our research involves analyzing 30 samples recovered from COSC-2, which reached a depth of 2276 meters. Our objectives include evaluating their physical properties under pressures ranging from 5 to 200 MPa in a pressure vessel to determine P-wave and S-wave velocities. Additionally, UCS testing will be conducted to ascertain stress orientations, quantify stress magnitudes, and correlate findings with plate tectonics, fault systems, isostatic rebound, seismic hazard assessment, and other geophysical parameters. The ultimate aim is to extrapolate these insights to develop a comprehensive borehole strength model. Methodologies include borehole breakout mapping, core characterization, UCS testing for rock strength determination, and seismic velocity measurements to establish Vp and Vs correlations with rock properties.
