Geological sample preparation is a vital stage in the analytical process, given the highly variable nature of mineral samples. The purpose of sample preparation is the production of homogeneous sub-sample, representative of the material submitted to the laboratory.3.2 Geologic Time. Since 4.54 byr is a large chunk of time, geologists have divided it into more manageable chunks by creating a time scale. The commonly accepted time scale comes from the International Commission on Stratigraphy (Figure 3.1). It is continually revised as new research fine-tunes numbers between time scale divisions.Writing a recognition speech can be a daunting task.
