Geologist

About Me

My name is Andrei Ionut APOPEI, I’m 33 years old, and as my website suggests, I’m a geologist. What I love about #Geology is that it helps us find the "truth about Earth" and offers a constant feeling of discovery; looking at the simplest mineral on a molecular level is like describing a whole new world.

My interests in #Geology and informational techniques, applied to a wide range of problems in the field of geoscience, had finally been refined enough that I knew that one or two major topics are not enough for me. Currently, Mineralogy, Ore Geology, Vibrational spectrometry are the scientific fields that best fit my interests.

These domains share a strong link, allowing people to understand Earth’s evolution and for me, to share my knowledge and practical work to others (especially for my students).

Currently, I’m looking for a research grant in the field of 3D technologies applied in Geoscience and Cultural Heritage.

Outside my </working hours>, I dedicate my free time to: software and game development, web design, photography (especially micro- and macro-), video editing and some electronics.

Iridescence

This short film aims to bring to light the aesthetic qualities and iridescent properties of labradorite. For both students and geology enthusiasts of any age, iridescence (or Schiller effect) is an optical effect that 'attracts' them to deepen the field of Mineralogy. As a former geology student, the lessons on the optical properties of minerals were some of the most fascinating lessons that made me love mineralogy even more.

Film selected for the finals @ On the Rocks - Geological Film Festival (2021 edition) - in the experimental film category.

Museum of Mineralogy and Petrography

First geological museum in Romania, with more than 25000 samples of minerals, gemstones and rocks from all over the world. The museum has more than 25000 samples from all over the world. The oldest samples belong to the Krantz collection, purchased by Prof. Grigore Cobălcescu in 1888 from Dr. F. Krantz, Rheinisches Mineralien-Kontor, Bonn, Germany.

Virtual Microscope - Minerals

The Virtual Microscope - Minerals is a professional and interactive virtual petrographic microscope that allows geologists to examine and explore minerals and their microscopic features (this app contains only minerals in thin sections using transmitted light - non-opaque minerals).

The Virtual Microscope - Minerals makes Optical Mineralogy easier to examine a thin section and to understand the characteristic properties of each mineral without a petrographic microscope, which is known to be very expensive. It is mainly addressed to geoscience students/geologists as a guide in individual or supervised laboratory work.
