Identification of cores and core logging

To calculate RQD.(ROCK QUALITY DESIGNATION)

Objectives

  • To explain a factual, accurate, and concise record of the important geological and physical characteristics of engineering significance of rocks

  • To determine the lithology (rock types), mineralogy, potential geological history, structure and alteration zones through a tiny piece of cylindrical rock drilled and removed from a potential mineral deposit.

  • To measure and record information of the rock type.

  • To determine grade, size and mineability of a potential mineral deposit drill cores are relied on.
