F THEORY THEORY OF HEAT One of the theories of or the origin of oil is that it was produced by bythe tie the action of intense heat working on certain rocks s and other substances sub sub- stances beneath the surface of or the ground At certain temperatures these substances placed in the micro-furnace micro hav have been found to change their nature and structure inS as ak observed under the microscope Certain elements of the same substance sub sub- substance stance will change at different temperatures Through the microscope the geologist can observe the changes and note the temperatures that produce pro pro- duce them In this way it is hoped that some hint of how oil came tobe to tobe be formed may be obtained GERMS OF The microscope unlocks another secret of the rocks when applied to the germs or to be found in the strata far tar below the surf sur sur- f face ce These germs are in reality tiny sea animals that died of years rears ago go and whose bodies are arenow arenow now nou embedded in the rock Each ge geological age had bad its Us own particular lar Jar which appear to be small sea shells when placed under the the microscope The geologist can determine the age of any rock and at what depth In the earth it should b be found by studying these bugs I Discussions on this subject which f is ig one of the very latest in petroleum petroleum petroleum petro petro- leum geology will occupy much of the program According to G. G Dallas Hanna of ofSan ofSan San n Francisco E. E Call CalI Brown of California C was the first to discover the practical application of the Mr 11 Hanna is to read a paper on the subject More 1 than seven hundred geologists geologists from all parts of the United States tates are here for the convention |
