Geological Eras
Geological Eras When H. P. Blavatsky was writing about the age of the earth in
The Secret Doctrine she compared the teachings of the scientists of that time and found nothing but confusion and uncertainty as to geological figures. However, Professor Lefevre in his
Philosophy adopted an original method of interpreting the data available. Instead of trying to reach exact figures in regard to the length of the entire fossil-bearing period of sedimentation from the Laurentian period to the present day, or of its subdivisions, he worked out the
relative durations of the sedimentary deposits. With this for a background the actual duration of the eras and periods could easily be calculated when reliable evidence was found. Lefevre's studies were based on the erosion of rocks and the deposition of sediments, and his conclusions have stood with little modification till now. H. P. Blavatsky noticed that his estimates of the
relative duration of the geological ages agreed fairly well with the 'esoteric' information in her possession, and so by adapting her knowledge of the real figures to Lefevre's proportional scale she constructed a time table which, she says, approximates the truth "in almost every particular." Her total of "320,000,000 years of sedimentation" is much less than that of modern geologists, even though she includes the Laurentian period in her table, which they omit. Her "Esoteric" table (Sd 2:710) is as follows:
