Could Sherlock Holmes Have Been a Good Geologist?/Summary
The efficiency of a field geologist depends of his/her capacity of observation. The correct observation of a phenomenon contributes to its better understanding and allows a more rational and effective orientation of the investigation. That is why is so important to master the steps that guarantee a correct observation of any phenomenon. These steps are: (1) the perception of the object, (2) the primary observation (first impressions) and (3) the elaboration of a plan for the description of the phenomenon. Here we included the statistical pre elaboration of the data, and a model for the codification of the information during lithogeochemical sampling.
