With the Microsoft Teams as the virtual platform, the Mines and Geosciences Bureau-Central Office (MGB-CO) organized a five-day virtual training on basic mineragraphic techniques from 2021. October 18 to 22. This was participated by select participants from the MGB-CO and MGB Regional Offices.
The objectives of the training include: to learn proper sample collection and preparation techniques for ore minerals; to understand the functions of a reflected light microscope; to identify ore minerals in polished sections based on their optical’ properties; to recognize textures and interpret their implications on ore mineral formation; and to derive a paragenetic sequence from the textures and ore mineral relationships.
The training lectures were given by Dr. Jillian Aira S. Gabo-Ratio of the University of the Philippines – National Institute of Geological Sciences (UP-NIGS). Multiple exercises, using megascopic pictures and photomicrographs of ore minerals, were done by the participants to apply the topics discussed by the resource speaker.
Mineragraphy proves to be vital in understanding how the ore minerals formed and the sequence to which these materials deposited. This is crucial when dealing with mineral deposits under exploration stages as this implies critical information to the mode of deposition of the commodity under investigation. The five-day virtual training amplified this importance and made sure that the participants were equipped with newly acquired knowledge for this field of expertise.
