16. THE SONIC OR ACOUSTIC LOG 16.1 Introduction

2014-5-21 · 16.1 Introduction The sonic or acoustic log measures the travel time of an elastic wave through the formation. This information can also be used to derive the velocity of elastic waves through the formation. Its main use is to provide information to support and calibrate seismic data and to derive the porosity of a formation. The main uses are:

Metals from Ores: An Introduction

2019-8-24 · While dolomite, (Mg,Ca)CO 3, is used for producing metallic magnesium and to some extent as a refractory, magnetite, MgCO 3, is used mainly as a refractory: hence it is classified as a non-metallic mineral. One reason for that is that MgO prepared from magnetite has a higher melting point than (Mg, Ca)O prepared from dolomite
